Adds a new GitHub issue template for reporting documentation-related suggestions, inconsistencies, or improvements.
This template helps contributors provide clear, categorized feedback on docs, making it easier to track and prioritize structural or content-related issues separately from codebase bugs or feature requests.
Includes fields for:
- Affected document/section
- Description of the issue
- Proposed solution
- Type of documentation issue
- Optional implementation offer
Helps improve overall clarity, uniformity, and contributor experience with documentation.
This patch improves the resilience of the guess_icon function by sanitizing mac, vendor, and name fields to avoid crashes caused by unexpected data types (e.g., numeric hostnames).
Specifically:
mac is now cast to a string before being uppercased, with a newly added fallback to "00:00:00:00:00:00" if empty or invalid.
vendor is sanitized to a string before lowercasing, still defaulting to "unknown".
name is cast to a string before lowercasing, still falling back to "(unknown)" when empty.
This change not only resolves the error caused by numeric-only hostnames (which triggered an AttributeError due to calling .lower() on an int), but also proactively prevents similar crashes from malformed or unexpected input in the future.
References: Fixes issue #1088 and also let's me sleep a little easier tonight.
1/ Fix {} arround user_notifications.json file => if there is just one file, this create a file named "{user_notifications.json} ;)
2/ Fix group for the above file
This wasn't working for EMQX due to callback trigger delays it never connected. Also added a reconnect feature and a client id so it looks better in the EMQX connection dashboard. No confirmed to be working with Mosquitto and EMQX
Removed DEFER from ui_components as the device details page would not populate any more and the browser console would throw errors re function not found
Chnaged client creation logic to V2 API as we are already using Paho2.0. Chnaged version selection from Paho version (which should not have been a user choice) to MQTT Protocol selection, which can be v3 or v5. Most modern MQQTT brokers like Mosquitta or EMQX support v5.

<summary>❓ Why use Net <b>Alert</b><sup>x</sup>?</summary>
## 📦 Features
<hr>
### Scanners
Most of us don't know what's going on on our home network, but we want our family and data to be safe. _Command-line tools_ are great, but the output can be _hard to understand_ and action if you are not a network specialist.
The app scans your network for **New devices**, **New connections** (re-connections), **Disconnections**, **"Always Connected" devices down**, Devices **IP changes** and **Internet IP address changes**. Discovery & scan methods include: **arp-scan**, **Pi-hole - DB import**, **Pi-hole - DHCP leases import**, **Generic DHCP leases import**, **UNIFI controller import**, **SNMP-enabled router import**. Check the [Plugins](https://github.com/jokob-sk/NetAlertX/tree/main/docs/PLUGINS.md#readme) docs for a full list of avaliable plugins.
Net <b>Alert</b><sup>x</sup> gives you peace of mind. _Visualize and immediately report 📬_ what is going on in your network - this is the first step to enhance your _network security 🔐_.
### Notification gateways
Net <b>Alert</b><sup>x</sup> combines several network and other scanning tools 🔍 with notifications 📧 into one user-friendly package 📦.
Send notifications to more than 80+ services, including Telegram via [Apprise](https://hub.docker.com/r/caronc/apprise), or use native [Pushsafer](https://www.pushsafer.com/), [Pushover](https://www.pushover.net/), or [NTFY](https://ntfy.sh/) publishers.
Set up a _kill switch ☠_ for your network via a smart plug with the available [Home Assistant](https://github.com/jokob-sk/NetAlertX/blob/main/docs/HOME_ASSISTANT.md) integration. Implement custom automations with the [CSV device Exports 📤](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/csv_backup), [Webhooks](https://github.com/jokob-sk/NetAlertX/blob/main/docs/WEBHOOK_N8N.md), or [API endpoints](https://github.com/jokob-sk/NetAlertX/blob/main/docs/API.md) features.
### Integrations and Plugins
Extend the app if you want to create your own scanner [Plugin](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins#readme) and handle the results and notifications in Net <b>Alert</b><sup>x</sup>.
Feed your data and device changes into [Home Assistant](https://github.com/jokob-sk/NetAlertX/blob/main/docs/HOME_ASSISTANT.md), read [API endpoints](https://github.com/jokob-sk/NetAlertX/blob/main/docs/API.md), or use [Webhooks](https://github.com/jokob-sk/NetAlertX/blob/main/docs/WEBHOOK_N8N.md) to setup custom automation flows. You can also
build your own scanners with the [Plugin system](https://github.com/jokob-sk/NetAlertX/tree/main/docs/PLUGINS.md#readme) in as little as [15 minutes](https://www.youtube.com/watch?v=cdbxlwiWhv8).
Looking forward to your contributions if you decide to share your work with the community ❤.

The [workflows module](https://github.com/jokob-sk/NetAlertX/blob/main/docs/WORKFLOWS.md) allows to automate repetitive tasks, making network management more efficient. Whether you need to assign newly discovered devices to a specific Network Node, auto-group devices from a given vendor, unarchive a device if detected online, or automatically delete devices, this module provides the flexibility to tailor the automations to your needs.
...or explore all the [documentation here](https://jokob-sk.github.io/NetAlertX/).
## 🔐 Security & Privacy
NetAlertX scans your local network and can store metadata about connected devices. By default, all data is stored **locally**. No information is sent to external services unless you explicitly configure notifications or integrations.
To further secure your installation:
- Run it behind a reverse proxy with authentication
- Use firewalls to restrict access to the web UI
- Regularly update to the latest version for security patches
See [Security Best Practices](https://github.com/jokob-sk/NetAlertX/security) for more details.
## ❓ FAQ
**Q: Why don’t I see any devices?**
A: Ensure the container has proper network access (e.g., use `--network host` on Linux). Also check that your scan method is properly configured in the UI.
**Q: Does this work on Wi-Fi-only devices like Raspberry Pi?**
A: Yes, but some scanners (e.g. ARP) work best on Ethernet. For Wi-Fi, try SNMP, DHCP, or Pi-hole import.
**Q: Will this send any data to the internet?**
A: No. All scans and data remain local, unless you set up cloud-based notifications.
**Q: Can I use this without Docker?**
A: Yes! You can install it bare-metal. See the [bare metal installation guide](https://github.com/jokob-sk/NetAlertX/blob/main/docs/HW_INSTALL.md).
**Q: Where is the data stored?**
A: In the `/config` and `/db` folders, mapped in Docker. Back up these folders regularly.
## 🐞 Known Issues
- Some scanners (e.g. ARP) may not detect devices on different subnets. See the [Remote networks guide](https://github.com/jokob-sk/NetAlertX/blob/main/docs/REMOTE_NETWORKS.md) for workarounds.
- Wi-Fi-only networks may require alternate scanners for accurate detection.
- Notification throttling may be needed for large networks to prevent spam.
- On some systems, elevated permissions (like `CAP_NET_RAW`) may be needed for low-level scanning.

## 📕 Basic Usage
> [!WARNING]
> You will have to run the container on the `host` network.
> You will have to run the container on the `host` network and specify `SCAN_SUBNETS` unless you use other [plugin scanners](https://github.com/jokob-sk/NetAlertX/blob/main/docs/PLUGINS.md). The initial scan can take a few minutes, so please wait 5-10 minutes for the initial discovery to finish.
```yaml
docker run -d --rm --network=host \
-v local/path/config:/app/config \
-v local/path/db:/app/db \
-v local_path/config:/app/config \
-v local_path/db:/app/db \
--mount type=tmpfs,target=/app/api \
-e PUID=200 -e PGID=300 \
-e TZ=Europe/Berlin \
-e PORT=20211 \
jokobsk/netalertx:latest
ghcr.io/jokob-sk/netalertx:latest
```
- The initial scan can take up to 15min (with 50 devices and MQTT). Subsequent ones 3 and 5 minutes so wait that long for all of the scans to run.

### (If UI is not available) Modify the config (`app.conf`)
### Initial setup
- The preferred way is to manage the configuration via the Settings section in the UI.
- You can modify [app.conf](https://github.com/jokob-sk/NetAlertX/tree/main/config) directly, if needed.
- If unavailable, the app generates a default `app.conf` and `app.db` file on the first run.
- The preferred way is to manage the configuration via the Settings section in the UI, if UI is inaccessible you can modify [app.conf](https://github.com/jokob-sk/NetAlertX/tree/main/back) in the `/app/config/` folder directly
### ⚙ Important settings
#### Setting up scanners
These are the most important settings to get at least some output in your Devices screen. Usually, only one approach is used, but you can combine these approaches.
| arp-scan, nmap-scan | `SCAN_SUBNETS` | See the documentation on how [to setup SUBNETS, VLANs & limitations](https://github.com/jokob-sk/NetAlertX/blob/main/docs/SUBNETS.md) |
| PiHole | `PIHOLE_RUN` | There are 2 approaches how to get PiHole devices imported. Via the PiHole import (`PIHOLE`) plugin or DHCP leases (`DHCPLSS`) plugin. The `PIHOLE` plugin requires you to map the PiHole database, as mentioned above. |
| dhcp.leases | `DHCPLSS_RUN` | You need to map `:/etc/myfiles/dhcp.leases` in the `docker-compose.yml` file if you enable this setting. This path has to be matched with a corresponding `DHCPLSS_paths_to_check` setting entry (check the [DHCPLSS plugin readme](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/dhcp_leases#overview) for details). |
You have to specify which network(s) should be scanned. This is done by entering subnets that are accessible from the host. If you use the default `ARPSCAN` plugin, you have to specify at least one valid subnet and interface in the `SCAN_SUBNETS` setting. See the documentation on [How to set up multiple SUBNETS, VLANs and what are limitations](https://github.com/jokob-sk/NetAlertX/blob/main/docs/SUBNETS.md) for troubleshooting and more advanced scenarios.
If you are running PiHole you can synchronize devices directly. Check the [PiHole configuration guide](https://github.com/jokob-sk/NetAlertX/blob/main/docs/PIHOLE_GUIDE.md) for details.
> [!NOTE]
> It's recommended to use the same schedule interval for all plugins responsible for discovering new devices.
> You can bulk-import devices via the [CSV import method](https://github.com/jokob-sk/NetAlertX/blob/main/docs/DEVICES_BULK_EDITING.md).

NetAlertX comes with a simple API. These API endpoints are static files, that are periodically updated based on your settings.
NetAlertX comes with a couple of API endpoints. All requests need to be authorized (executed in a logged in browser session) or you have to pass the value of the `API_TOKEN` settings as authorization bearer, for example:
- The `query` parameter contains the GraphQL query as a string.
- The `variables` parameter contains the input variables for the query.
2.**Query Variables**:
-`page`: Specifies the page number of results to fetch.
-`limit`: Specifies the number of results per page.
-`sort`: Specifies the sorting options, with `field` being the field to sort by and `order` being the sort order (`asc` for ascending or `desc` for descending).
-`search`: A search term to filter the devices.
-`status`: The status filter to apply (valid values are `my_devices` (determined by the `UI_MY_DEVICES` setting), `connected`, `favorites`, `new`, `down`, `archived`, `offline`).
3.**`curl` Command**:
- The `-X POST` option specifies that we are making a POST request.
- The `-H "Content-Type: application/json"` option sets the content type of the request to JSON.
- The `-d` option provides the request payload, which includes the GraphQL query and variables.
### Sample Response
The response will be in JSON format, similar to the following:
```json
{
"data":{
"devices":{
"devices":[
{
"rowid":1,
"devMac":"00:11:22:33:44:55",
"devName":"Device 1",
"devOwner":"Owner 1",
"devType":"Type 1",
"devVendor":"Vendor 1",
"devLastConnection":"2025-01-01T00:00:00Z",
"devStatus":"connected"
},
{
"rowid":2,
"devMac":"66:77:88:99:AA:BB",

}
],
"count":2
}
}

## Data and cackup storage
To decide on a backup strategy, check where the data is stored:
## Backup strategies
### Core Configuration
The safest approach to backups is to backup everything, by taking regular file system backups of the `/db` and `/config` folders (I use [Kopia](https://github.com/kopia/kopia)).
The core application configuration is in the `app.conf` file (See [Settings System](https://github.com/jokob-sk/NetAlertX/blob/main/docs/SETTINGS_SYSTEM.md) for details), such as:
Arguably, the most time is spent setting up the device list, so if only one file is kept I'd recommend to have a latest backup of the `devices_<timestamp>.csv` or `devices.csv` file, followed by the `app.conf` and `workflows.json` files. You can also download `app.conf` and `devices.csv` file in the Maintenance section:
- Notification settings
- Scanner settings
- Scheduled maintenance settings
- UI configuration (80%)
### Core Device Data
The core device data is backed up to the `devices_<timestamp>.csv` file via the [CSV Backup `CSVBCKP` Plugin](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/csv_backup). This file contains data, such as:
- Device names
- Device Icons
- Device Network configuration
- Device categorization
### Historical data
Historical data is stored in the `app.db` database (See [Database overview](https://github.com/jokob-sk/NetAlertX/blob/main/docs/DATABASE.md) for details). This data includes:
- Plugin objects
- Plugin historical entries
- History of Events, Notifications, Workflow Events
- Presence History
## 🧭 Backup strategies
The safest approach to backups is to backup all of the above, by taking regular file system backups (I use [Kopia](https://github.com/kopia/kopia)).
Arguably, the most time is spent setting up the device list, so if only one file is kept I'd recommend to have a latest backup of the `devices_<timestamp>.csv` file, followed by the `app.conf` file.

### Scenario 1: Full backup
End-result: Full restore

#### 💾 Source artifacts:
-`/db/app.db` (uncorrupted)
-`/config/app.conf`
-`/app/db/app.db` (uncorrupted)
-`/app/config/app.conf`
-`/app/config/workflows.json`
#### Recovery:
#### 📥 Recovery:
To restore the application map the above files as described in the [Setup documentation](https://github.com/jokob-sk/NetAlertX/blob/main/dockerfiles/README.md#docker-paths).
### Scenario 2: Corrupted database
End-result: Partial restore (historical data & configurations from the Maintenance section will be missing)
End-result: Partial restore (historical data and some plugin data will be missing)

-`/app/config/devices_<timestamp>.csv` or `/app/config/devices.csv`
-`/app/config/workflows.json`
#### Recovery:
#### 📥 Recovery:
Even with a corrupted database you can recover what I would argue is 99% of the configuration (except of a couple of settings under Maintenance).
Even with a corrupted database you can recover what I would argue is 99% of the configuration.
-map the `/config/app.conf` file as described in the [Setup documentation](https://github.com/jokob-sk/NetAlertX/blob/main/dockerfiles/README.md#docker-paths).
- rename the `devices_<timestamp>.csv` to `devices.csv` and place it in the `/config` folder
- Restore the `devices.csv` backup via the [Maintenance section](https://github.com/jokob-sk/NetAlertX/blob/main/docs/DEVICES_BULK_EDITING.md)
-upload the `app.conf` and `workflows.json` files into the mounted `/app/config/` folder as described in the [Setup documentation](https://github.com/jokob-sk/NetAlertX/blob/main/dockerfiles/README.md#docker-paths).
- rename the `devices_<timestamp>.csv` to `devices.csv` and place it in the `/app/config` folder
- Restore the `devices.csv` backup via the [Maintenance section](./DEVICES_BULK_EDITING.md)
## Data and backup storage
To decide on a backup strategy, check where the data is stored:
### Core Configuration
The core application configuration is in the `app.conf` file (See [Settings System](./SETTINGS_SYSTEM.md) for details), such as:
- Notification settings
- Scanner settings
- Scheduled maintenance settings
- UI configuration
### Core Device Data
The core device data is backed up to the `devices_<timestamp>.csv` or `devices.csv` file via the [CSV Backup `CSVBCKP` Plugin](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/csv_backup). This file contains data, such as:
- Device names
- Device icons
- Device network configuration
- Device categorization
- Device custom properties data
### Historical data
Historical data is stored in the `app.db` database (See [Database overview](./DATABASE.md) for details). This data includes:
- Plugin objects
- Plugin historical entries
- History of Events, Notifications, Workflow Events
Often if the application is misconfigured the `Loading...` dialog is continuously displayed. This is most likely caused by the backed failing to start. The **Maintenance -> Logs** section should give you more details on what's happening. If there is no exception, check the Portainer log, or start the container in the foreground (without the `-d` parameter) to observe any exceptions. It's advisable to enable `trace` or `debug`. Check the [Debug tips](./DEBUG_TIPS.md) on detailed instructions.
### Incorrect SCAN_SUBNETS
One of the most common issues is not configuring `SCAN_SUBNETS` correctly. If this setting is misconfigured you will only see one or two devices in your devices list after a scan. Please read the [subnets docs](./SUBNETS.md) carefully to resolve this.
### Duplicate devices and notifications
The app uses the MAC address as an unique identifier for devices. If a new MAC is detected a new device is added to the application and corresponding notifications are triggered. This means that if the MAC of an existing device changes, the device will be logged as a new device. You can usually prevent this from happening by changing the device configuration (in Android, iOS, or Windows) for your network. See the [Random Macs](./RANDOM_MAC.md) guide for details.
### Permissions
Make sure you [File permissions](./FILE_PERMISSIONS.md) are set correctly.
* If facing issues (AJAX errors, can't write to DB, empty screen, etc,) make sure permissions are set correctly, and check the logs under `/app/log`.
* To solve permission issues you can try setting the owner and group of the `app.db` by executing the following on the host system: `docker exec netalertx chown -R www-data:www-data /app/db/app.db`.
* If still facing issues, try to map the app.db file (⚠ not folder) to `:/app/db/app.db` (see [docker-compose Examples](https://github.com/jokob-sk/NetAlertX/blob/main/dockerfiles/README.md#-docker-composeyml-examples) for details)
### Container restarts / crashes
* Check the logs for details. Often a required setting for a notification method is missing.
### unable to resolve host
* Check that your `SCAN_SUBNETS` variable is using the correct mask and `--interface`. See the [subnets docs for details](./SUBNETS.md).
### Invalid JSON
Check the [Invalid JSON errors debug help](./DEBUG_INVALID_JSON.md) docs on how to proceed.
### sudo execution failing (e.g.: on arpscan) on a Raspberry Pi 4
> sudo: unexpected child termination condition: 0
Resolution based on [this issue](https://github.com/linuxserver/docker-papermerge/issues/4#issuecomment-1003657581)
The link above will probably break in time too. Go to https://packages.debian.org/sid/armhf/libseccomp2/download to find the new version number and put that in the url.
### Only Router and own device show up
Make sure that the subnet and interface in `SCAN_SUBNETS` are correct. If your device/NAS has multiple ethernet ports, you probably need to change `eth0` to something else.
### Losing my settings and devices after an update
If you lose your devices and/or settings after an update that means you don't have the `/app/db` and `/app/config` folders mapped to a permanent storage. That means every time you update these folders are re-created. Make sure you have the [volumes specified correctly](./DOCKER_COMPOSE.md) in your `docker-compose.yml` or run command.
### The application is slow
Slowness is usually caused by incorrect settings (the app might restart, so check the `app.log`), too many background processes (disable unnecessary scanners), too long scans (limit the number of scanned devices), too many disk operations, or some maintenance plugins might have failed. See the [Performance tips](./PERFORMANCE.md) docs for details.

This functionality allows you to define **custom properties** for devices, which can store and display additional information on the device listing page. By marking properties as "Show", you can enhance the user interface with quick actions, notes, or external links.
### Key Features:
- **Customizable Properties**: Define specific properties for each device.
- **Visibility Control**: Choose which properties are displayed on the device listing page.
- **Interactive Elements**: Include actions like links, modals, and device management directly in the interface.
---
## Defining Custom Properties
Custom properties are structured as a list of objects, where each property includes the following fields:
Visible properties (`CUSTPROP_show: true`) are displayed as interactive icons in the device listing. Each icon can perform one of the following actions based on the `CUSTPROP_type`:
1.**Modals (e.g., Show Notes)**:

The GraphQL server is an API middle layer, running on it's own port specified by `GRAPHQL_PORT`, to retrieve and show the data in the UI. It can also be used to retrieve data for custom third party integarions. Check the [API documentation](./API.md) for details.
The most common issue is that the GraphQL server doesn't start properly, usually due to a **port conflict**. If you are running multiple NetAlertX instances, make sure to use **unique ports** by changing the `GRAPHQL_PORT` setting. The default is `20212`.
## How to update the `GRAPHQL_PORT` in case of issues
As a first troubleshooting step try changing the default `GRAPHQL_PORT` setting. Please remember NetAlertX is running on the host so any application uising the same port will cause issues.
### Updating the setting via the Settings UI
Ideally use the Settings UI to update the setting under General -> Core -> GraphQL port:
You might need to temporarily stop other applications or NetAlertX instances causing conflicts to update the setting. The `API_TOKEN` is used to authenticate any API calls, including GraphQL requests.
### Updating the `app.conf` file
If the UI is not accessible, you can directly edit the `app.conf` file in your `/config` folder:
In your browser open the dev console (usually F12) and navigate to the Network tab where you can filter GraphQL requests (e.g., reload the Devices page).

Sometimes specific log sections are needed to debug issues. The Devices and CurrentScan table data is sometimes needed to figure out what's wrong.
* If facing issues (AJAX errors, can't write to DB, empty screen, etc,) make sure permissions are set correctly, and check the logs under `/app/front/log`.
* To solve permission issues you can try setting the owner and group of the `app.db` by executing the following on the host system: `docker exec netalertx chown -R www-data:www-data /app/db/app.db`.
* If still facing issues, try to map the app.db file (⚠ not folder) to `:/app/db/app.db` (see [docker-compose Examples](https://github.com/jokob-sk/NetAlertX/blob/main/dockerfiles/README.md#-docker-composeyml-examples) for details)

This module is responsible for inferring the most likely **device type** and **icon** based on minimal identifying data like MAC address, vendor, IP, or device name.
It does this using a set of heuristics defined in an external JSON rules file, which it evaluates **in priority order**.
>[!NOTE]
> You can find the full source code of the heuristics module in the `device_heuristics.py` file.
---
## JSON Rule Format
Rules are defined in a file called `device_heuristics_rules.json` (located under `/back`), structured like:
> Feel free to raise a PR in case you'd like to add any rules into the `device_heuristics_rules.json` file. Please place new rules into the correct position and consider the priority of already available rules.
| `dev_type` | `string` | Type to assign if rule matches (e.g. `"Gateway"`, `"Phone"`) |
| `icon_html` | `string` | Icon (HTML string) to assign if rule matches. Encoded to base64 at load time. |
| `matching_pattern` | `array` | List of `{ mac_prefix, vendor }` objects for first strict and then loose matching |
| `name_pattern` | `array`*(optional)* | List of lowercase substrings (used with regex) |
| `ip_pattern` | `array`*(optional)* | Regex patterns to match IPs |
**Order in this array defines priority** — rules are checked top-down and short-circuit on first match.
---
## Matching Flow (in Priority Order)
The function `guess_device_attributes(...)` runs a series of matching functions in strict order:
1. MAC + Vendor → `match_mac_and_vendor()`
2. Vendor only → `match_vendor()`
3. Name pattern → `match_name()`
4. IP pattern → `match_ip()`
5. Final fallback → defaults defined in the `NEWDEV_devIcon` and `NEWDEV_devType` settings.
### Use of default values
The guessing process runs for every device **as long as the current type or icon still matches the default values**. Even if earlier heuristics return a match, the system continues evaluating additional clues — like name or IP — to try and replace placeholders.
```python
# Still considered a match attempt if current values are defaults
In other words: if the type or icon is still `"unknown"` (or matches the default), the system assumes the match isn’t final — and keeps looking. It stops only when both values are non-default (defaults are defined in the `NEWDEV_devIcon` and `NEWDEV_devType` settings).
---
## Match Behavior (per function)
These functions are executed in the following order:
- Select "Devices" in the menu on the left of the screen
- Find the device you want to edit in the central table
- Go to the device page by clicking on the device name or status
- Press "Details" tab of the device
- Edit the device data
- Press the "Save" button
The Main Info section is where most of the device identifiable information is stored and edited. Some of the information is autodetected via various plugins. Initial values for most of the fields can be specified in the `NEWDEV` plugin.

- **Name**: Friendly device name. Autodetected via various 🆎 Name discovery [plugins](https://github.com/jokob-sk/NetAlertX/blob/main/docs/PLUGINS.md). The app attaches `(IP match)` if the name is discovered via an IP match and not MAC match which could mean the name could be incorrect as IPs might change.
- **Icon**: Partially autodetected. Select an existing or [add a custom icon](./ICONS.md). You can also auto-apply the same icon on all devices of the same type.
- **Owner**: Device owner (The list is self-populated with existing owners and you can add custom values).
- **Type**: Select a device type from the dropdown list (`Smartphone`, `Tablet`,
`Laptop`, `TV`, `router`, etc.) or add a new device type. If you want the device to act as a **Network device** (and be able to be a network node in the Network view), select a type under Network Devices or add a new Network Device type in Settings. More information can be found in the [Network Setup docs](./NETWORK_TREE.md).
- **Vendor**: The manufacturing vendor. Automatically updated by NetAlertX when empty or unknown, can be edited.

The latest versions of some operating systems (IOS and Android) incorporate a
new & interesting functionality to improve privacy: **Random MACs**.
This functionality allows you to **hide the true MAC** of the device and
**assign a random MAC** when we connect to WIFI networks.
This behavior is especially useful when connecting to WIFI's that we do not
know, but it **is totally useless when connecting to our own WIFI's** or known
networks.
**I recommend disabling this operation when connecting our devices to our own
WIFI's**, in this way, NetAlertX will be able to identify the device, and it
will not identify it as a new device every so often (every time IOS or Android
decides to change the MAC).

> Replace `/development` with the path where your code files will be stored. The default container name is `netalertx` so there might be a conflict with your running containers.
## Development Guidelines
Before starting development, please scan the below development guidelines.
### Priority Order (Highest to Lowest)
1. 🔼 Fixing core bugs that lack workarounds.
2. 🔵 Adding core functionality that unlocks other features (e.g., plugins).
3. 🔵 Refactoring to enable faster development.
4. 🔽 UI improvements (PRs welcome).
### Design Philosophy
Focus on core functionality and integrate with existing tools rather than reinventing the wheel.
Examples:
- Using **Apprise** for notifications instead of implementing multiple separate gateways.
- Implementing **regex-based validation** instead of one-off validation for each setting.
> [!NOTE]
> UI changes have lower priority, however, PRs are welcome, but **keep them small & focused**.
> The container needs to run in `network_mode:"host"`. This also means that not all functionality is supported on a Windows host as Docker for Windows doesn't support this networking option.
### Example 1
```yaml
services:
netalertx:
container_name:netalertx
# use the below line if you want to test the latest dev image
# image: "ghcr.io/jokob-sk/netalertx-dev:latest"
image:"ghcr.io/jokob-sk/netalertx:latest"
network_mode:"host"
restart:unless-stopped
volumes:
- local_path/config:/app/config
- local_path/db:/app/db
# (optional) useful for debugging if you have issues setting up the container
- local_path/logs:/app/log
# (API: OPTION 1) use for performance
- type:tmpfs
target:/app/api
# (API: OPTION 2) use when debugging issues
# - local_path/api:/app/api
environment:
- TZ=Europe/Berlin
- PORT=20211
```
To run the container execute: `sudo docker-compose up -d`
### Example 2

restart:always
volumes:
- ./netalertx/db:/app/db
- ./netalertx/config:/app/config

-o parent=eno1 \ # 🔧 Replace with your network interface (e.g., eth0, eno1)
# Managing File Permissions for NetAlertX on Nginx with Docker
NetAlertX runs on an Nginx web server. On Alpine Linux, Nginx operates as the `nginx` user (user ID 101, group ID 82 - `www-data`). Consequently, files accessed or written by the NetAlertX application are owned by `nginx:www-data`.
> [!TIP]
> If you are facing permission issues, try to start the container without mapping your volumes. If that works, then the issue is permission related. You can try e.g., the following command:
> ```
> docker run -d --rm --network=host \
> -e TZ=Europe/Berlin \
> -e PUID=200 -e PGID=200 \
> -e PORT=20211 \
> ghcr.io/jokob-sk/netalertx:latest
> ```
NetAlertX runs on an Nginx web server. On Alpine Linux, Nginx operates as the `nginx` user (if PUID and GID environment variables are not specified, nginx user UID will be set to 102, and its supplementary group `www-data` ID to 82). Consequently, files accessed or written by the NetAlertX application are owned by `nginx:www-data`.
Upon starting, NetAlertX changes the ownership of files on the host system mapped to `/app/config` and `/app/db` in the container to `nginx:www-data`. This ensures that Nginx can access and write to these files. Since the user in the Docker container is mapped to a user on the host system by ID:GID, the files in `/app/config` and `/app/db` on the host system are owned by a user with the same ID and GID (ID 101 and GID 82). On different systems, this ID:GID may belong to different users (on Debian, the user with ID 82 is `uuidd`), or there may not be a user with ID 82 at all.
Upon starting, NetAlertX changes nginx user UID and www-data GID to specified values (or defaults), and the ownership of files on the host system mapped to `/app/config` and `/app/db` in the container to `nginx:www-data`. This ensures that Nginx can access and write to these files. Since the user in the Docker container is mapped to a user on the host system by ID:GID, the files in `/app/config` and `/app/db` on the host system are owned by a user with the same ID and GID (defaults are ID 102 and GID 82). On different systems, this ID:GID may belong to different users, or there may not be a group with ID 82 at all.
While this generally isn't problematic, it can cause issues for host system users needing to access these files (e.g., backup scripts). If users other than root need access to these files, it is recommended to add those users to the group with GID 82. If that group doesn't exist, it should be created.

# Troubleshooting: Devices Show Offline When They Are Online
In some network setups, certain devices may intermittently appear as **offline** in NetAlertX, even though they are connected and responsive. This issue is often more noticeable with devices that have **higher IP addresses** within the subnet.
> [!NOTE]
>
> Network presence graph showing increased drop outs before enabling additional `ICMP` scans and continuous online presence after following this guide. This graph shows a sudden spike in drop outs probably caused by a device software update.
> 
## Symptoms
* Devices sporadically show as offline in the presence timeline.
* This behavior often affects devices with higher IPs (e.g., `192.168.1.240+`).
* Presence data appears inconsistent or unreliable despite the device being online.
## Cause
This issue is typically related to scanning limitations:
* **ARP scan timeouts** may prevent full subnet coverage.
* **Sole reliance on ARP** can result in missed detections:
* Some devices (like iPhones) suppress or reject frequent ARP requests.
* ARP responses may be blocked or delayed due to power-saving features or OS behavior.
* **Scanning frequency conflicts**, where devices ignore repeated scans within a short period.
## Recommended Fixes
To improve presence accuracy and reduce false offline states:
### ✅ Increase ARP Scan Timeout
Extend the ARP scanner timeout to ensure full subnet coverage:
```env
ARPSCAN_RUN_TIMEOUT=360
```
> Adjust based on your network size and device count.
### ✅ Add ICMP (Ping) Scanning
Enable the `ICMP` scan plugin to complement ARP detection. ICMP is often more reliable for detecting active hosts, especially when ARP fails.
### ✅ Use Multiple Detection Methods
A combined approach greatly improves detection robustness:
*`ARPSCAN` (default)
*`ICMP` (ping)
*`NMAPDEV` (nmap)
This hybrid strategy increases reliability, especially for down detection and alerting. See [other plugins](./PLUGINS.md) that might be compatible with your setup. See benefits and drawbacks of individual scan methods in their respective docs.
## Results
After increasing the ARP timeout and adding ICMP scanning (on select IP ranges), users typically report:

NetAlertX comes with MQTT support, allowing you to show all detected devices as devices in Home Assistant. It also supplies a collection of stats, such as number of online devices.
> [!TIP]
> You can install NetAlertX also as a Home Assistant addon [](https://my.home-assistant.io/redirect/supervisor_add_addon_repository/?repository_url=https%3A%2F%2Fgithub.com%2Falexbelgium%2Fhassio-addons) via the [alexbelgium/hassio-addons](https://github.com/alexbelgium/hassio-addons/) repository. This is only possible if you run a supervised instance of Home Assistant. If not, you can still run NetAlertX in a separate Docker container and follow this guide to configure MQTT.
## ⚠ Note
- Please note that discovery takes about ~10s per device.
- Deleting of devices is not handled automatically. Please use [MQTT Explorer](https://mqtt-explorer.com/) to delete devices in the broker (Home Assistant), if needed.
- For optimization reasons, the devices are not always fully synchronized. You can delete Plugin objects as described in the [MQTT plugin](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/_publisher_mqtt#forcing-an-update) docs to force a full synchronization.

NetAlertX comes with several logs that help to identify application issues.
For plugin-specific log debugging, please read the [Debug Plugins](./DEBUG_PLUGINS.md) guide.
When debugging any issue, increase the `LOG_LEVEL` Setting as per the [Debug tips](./DEBUG_TIPS.md) documentation.
## Main logs
You can find most of the logs exposed in the UI under _Maintenance -> Logs_.
If the UI is inaccessible, you can access them under `/app/log`.

In the _Maintennace -> Logs_ you can **Purge logs**, download the full log file or Filter the lines with some substring to narrow down your search.
## Plugin logging
If a Plugin supplies data to the main app it's done either vie a SQL query or via a script that updates the `last_result.log` file in the plugin log folder (`app/log/plugins/`). These files are processed at the end of the scan and deleted on successful processing.
The data is in most of the cases then displayed in the application under _Integrations -> Plugins_ (or _Device -> Plugins_ if the plugin is supplying device-specific data).

Name resolution in NetAlertX relies on multiple plugins to resolve device names from IP addresses. If you are seeing `(name not found)` as device names, follow these steps to diagnose and fix the issue.
> [!TIP]
> Before proceeding, make sure [Reverse DNS](./REVERSE_DNS.md) is enabled on your network.
> You can control how names are handled and cleaned using the `NEWDEV_NAME_CLEANUP_REGEX` setting.
> To auto-update Fully Qualified Domain Names (FQDN), enable the `REFRESH_FQDN` setting.
## Required Plugins
For best results, ensure the following name resolution plugins are enabled:
- **AVAHISCAN** – Uses mDNS/Avahi to resolve local network names.
- **NBTSCAN** – Queries NetBIOS to find device names.
- **NSLOOKUP** – Performs standard DNS lookups.
- **DIGSCAN** – Performs Name Resolution with the Dig utility (DNS).
You can check which plugins are active in your _Settings_ section and enable any that are missing.
There are other plugins that can supply device names as well, but they rely on bespoke hardware and services. See [Plugins overview](./PLUGINS.md) for details and look for plugins with name discovery (🆎) features.
## Checking Logs
If names are not resolving, check the logs for errors or timeouts.
See how to explore logs in the [Logging guide](./LOGGING.md).
Logs will show which plugins attempted resolution and any failures encountered.
## Adjusting Timeout Settings
If resolution is slow or failing due to timeouts, increase the timeout settings in your configuration, for example.
```ini
NSLOOKUP_RUN_TIMEOUT=30
```
Raising the timeout may help if your network has high latency or slow DNS responses.
## Checking Plugin Objects
Each plugin stores results in its respective object. You can inspect these objects to see if they contain valid name resolution data.
See [Logging guide](./LOGGING.md) and [Debug plugins](./DEBUG_PLUGINS.md) guides for details.
If the object contains no results, the issue may be with DNS settings or network access.
## Improving name resolution

Make sure you have a root device with the MAC `Internet` (No other MAC addresses are currently supported as the root node) set to a network device type (e.g.: **Type**:`Router`).
The **Network** page lets you map how devices connect — visually and logically.
It’s especially useful for planning infrastructure, assigning parent-child relationships, and spotting gaps.
> 💡 Tip: You can add dummy devices via the [Undiscoverables plugin](https://github.com/jokob-sk/NetAlertX/blob/main/front/plugins/undiscoverables/README.md)

> 💡 Tip: Export your configuration of the Network and Devices once in a while via the Export CSV feature under **Maintenance** -> **Backup/Restore** -> **CSV Export**.
To get started, you’ll need to define at least one root node and mark certain devices as network nodes (like Switches or Routers).
## ⚡Quick setup:
---
* Go to a Device you want to use as network device (network nodes, such as a Switch).
* Set the **Type** of such a device to one of the following: AP, Firewall, Gateway, PLC, Powerline, Router, Switch, USB LAN Adapter, USB WIFI Adapter and WLAN (you can create a custom network type device with in Settings -> General -> `NETWORK_DEVICE_TYPES`).
* Save and go to Network where the devices you've marked as network devices (by selecting the Type as mentioned above) will show up as tabs.
* You can now assign the Unassigend devices to the network node.
* If port is empty or 0 a wifi icon is rendered, otherwise a ethernet port icon.
Start by creating a root device with the MAC address `Internet`, if the application didn’t create one already.
This special MAC address (`Internet`) is required for the root network node — no other value is currently supported.
Set its **Type** to a valid network type — such as `Router` or `Gateway`.
> [!TIP]
> If you don’t have one, use the [Create new device](./DEVICE_MANAGEMENT.md#dummy-devices) button on the **Devices** page to add a root device.
> [!NOTE]
>
> [Bulk-edit devices](/docs/DEVICES_BULK_EDITING.md) by using the _CSV Export_ functionality in the _Maintenance_ section. You can use this to fix `Internet` node assignment issues.

## Example: Setting up a `raspberrypi` as a Switch
- In the (2) `Details` tab navigate to the the `Type` (3) dropdown and select the type `Switch` (4).
Let’s walk through setting up a device named `raspberrypi` to act as a network Switch that other devices connect through.
> Note: Only the following device types will show up as selectable Network nodes ( = devices you can connect other devices to):
> AP, Firewall, Gateway, Hypervisor, PLC, Powerline, Router, Switch, USB LAN Adapter, USB WIFI Adapter and WLAN. Custom types can be added via the `NETWORK_DEVICE_TYPES` setting.

- Assign a device to your root device from the `Node` (5) dropdown which has the MAC `Internet` (6) (Your name may differ, but the MAC needs to be set to `Internet` - this is done by default).
-Optionally assign a **Parent Node** (where this device connects to) and the **Relationship type** of the connection.
The `nic` relationship type can affect parent notifications — see the setting description and [Notifications documentation](./NOTIFICATIONS.md) for more.
- Notice the newly added `raspberrypi` (2) tab which now represents a network node, also showing up in the tree (3).
- As we asssigned the `raspberrypi` in the previous (1) Device details page section to the `Internet` parent network node in step (6), the link is also showing up in the tree diagram (4)
- We can now assign the device `(AppleTV)` (5) to this `raspberrypi` node, representing a network Switch in this example
> [!NOTE]
> Only certain device types can act as network nodes:
> You can add custom types via the `NETWORK_DEVICE_TYPES` setting.
### 3. Network page with 2 levels
- Click **Save**
- After clicking the `Assign` button in the previous section, the `(AppleTV)` (1) device is now connected to our `raspberrypi` (2).
---

### 2. Confirm The Device Appears as a Network Node
-You can see the`raspberrypi`represents the Network node type `Switch` (3)
- The `(AppleTV)` to `raspberrypi` connection is also displayed in the table of `Connected devices` (4).
- You can also see that our `raspberrypi` node is connected to it's Parent network device node with the MAC `Internet` (5). This connection again shows up in the tree (6) as well.
You can confirm that`raspberrypi`now acts as a network device in two places:
- Navigate to a different device and verify that `raspberrypi` now appears as an option for a **Parent Node**:
- Relationship lines may vary in color based on the selected Relationship type. These are editable on the device details page where you can also assign a parent node.
> Hovering over devices in the tree reveals connection details and tooltips for quick inspection.

## ✅ Summary
To configure devices on the **Network** page:
- Ensure a device with MAC `Internet` is set up as the root
- Assign valid **Type** values to switches, routers, and other supported nodes that represent network devices
- Use the **Assign** button to connect devices logically to their parent node

1.Completely disable the scanning of the device
2.**Alert all events**, connections, disconnections, IP changes (noisy, usually not recommended)
3.**Alert down** - alerts when a device goes down. This setting overrides disabled Alert All Events, so you will get a notification of a device going down even if you don't have Alert All Events ticked.
4.**Skip repeated notifications**, if for example you know there is a temporary issue and want to pause the same notification for this device for a given time.
1.**Alert Events** - Enables alerts of connections, disconnections, IP changes (down and down reconnected notifications are still sent even if this is disabled).
2.**Alert Down** - Alerts when a device goes down. This setting overrides a disabled **Alert Events** setting, so you will get a notification of a device going down even if you don't have **Alert Events** ticked. Disabling this will disable down and down reconnected notifications on the device.
3.**Skip repeated notifications**, if for example you know there is a temporary issue and want to pause the same notification for this device for a given time.
4.**Require NICs Online** - Indicates whether this device should be considered online only if all associated NICs (devices with the `nic` relationship type) are online. If disabled, the device is considered online if any NIC is online. If a NIC is online it sets the parent (this) device's status to online irrespectivelly of the detected device's status.

> [!NOTE]
> Please read through the [NTFPRCS plugin](https://github.com/jokob-sk/NetAlertX/blob/main/front/plugins/notification_processing/README.md) documentation to understand how device and global settings influence the notification processing.
On almost all plugins there are 2 core settings, `<plugin>_WATCH` and `<plugin>_REPORT_ON`.
1.`<plugin>_WATCH` specifies the columns which the app should watch. If watched columns change the device state is considered changed. This changed status is then used to decide to send out notifications based on the `<plugin>_REPORT_ON` setting.
2.`<plugin>_REPORT_ON` let's you specify on which events the app should notify you. This is related to the `<plugin>_WATCH` setting. So if you select `watched-changed` and in `<plugin>_WATCH` you only select `Watched_Value1`, then a notification is triggered if `Watched_Value1` is changed from the previous value, but no notification is send if `Watched_Value2` changes.
Click the **Read more in the docs.** Link at the top of each plugin to get more details on how the given plugin works.
In the Notification Processing section, you can specify blanket rules. These allow you to specify exceptions to the Plugin and Device settings and will override those.

2. Alert down after (`NTFPRCS_alert_down_time`) is useful if you want to wait for some time before the system sends out a down notification for a device. This is related to the on-device **Alert down** setting and only devices with this checked will trigger a down notification.
3. A filter to allow you to set device-specific exceptions to New devices being added to the app.
4. A filter to allow you to set device-specific exceptions to generated Events.
## Ignoring devices 🔕


You can completely ignore detected devices globally. This could be because your instance detects docker containers, you want to ignore devices from a specific manufacturer via MAC rules or you want to ignore devices on a specific IP range.

There are several ways to improve the application's performance. The application has been tested on a range of devices, from a Raspberry Pi 4 to NAS and NUC systems. If you are running the application on a lower-end device, carefully fine-tune the performance settings to ensure an optimal user experience.
## Common Causes of Slowness
Performance issues are usually caused by:
- **Incorrect settings** – The app may restart unexpectedly. Check `app.log` under **Maintenance → Logs** for details.
- **Too many background processes** – Disable unnecessary scanners.
- **Long scan durations** – Limit the number of scanned devices.
- **Excessive disk operations** – Optimize scanning and logging settings.
- **Increase scan intervals** (`<PLUGIN>_RUN_SCHD`) on busy networks or low-end hardware.
- **Extend scan timeouts** (`<PLUGIN>_RUN_TIMEOUT`) to prevent failures.
- **Reduce the subnet size** – e.g., from `/16` to `/24` to lower scan loads.
Some plugins have additional options to limit the number of scanned devices. If certain plugins take too long to complete, check if you can optimize scan times by selecting a scan range.
For example, the **ICMP plugin** allows you to specify a regular expression to scan only IPs that match a specific pattern.

## Storing Temporary Files in Memory
On systems with slower I/O speeds, you can optimize performance by storing temporary files in memory. This primarily applies to the `/app/api` and `/app/log` folders.
Using `tmpfs` reduces disk writes and improves performance. However, it should be **disabled** if persistent logs or API data storage are required.

NetAlertX comes with 2 plugins suitable for integarting with your existing PiHole instace. One plugin is using a direct SQLite DB connection, the other leverages the DHCP.leases file generated by PiHole. You can combine both approaches and also supplement it with other [plugins](/docs/PLUGINS.md).
## Approach 1: `DHCPLSS` Plugin - Import devices from the PiHole DHCP leases file
| `DHCPLSS_RUN` | When the plugin should run. | `schedule` |
| `DHCPLSS_RUN_SCHD` | If you run multiple device scanner plugins, align the schedules of all plugins to the same value. | `*/5 * * * *` |
| `DHCPLSS_paths_to_check` | You need to map the value in this setting in the `docker-compose.yml` file. The in-container path must contain `pihole` so it's parsed correctly. | `['/etc/pihole/dhcp.leases']` |
Check the [DHCPLSS plugin readme](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/dhcp_leases#overview) for details
### docker-compose changes
| Path | Description |
| :------------- | :------------- |
| `:/etc/pihole/dhcp.leases` | PiHole's `dhcp.leases` file. Required if you want to use PiHole `dhcp.leases` file. This has to be matched with a corresponding `DHCPLSS_paths_to_check` setting entry (the path in the container must contain `pihole`) |
## Approach 2: `PIHOLE` Plugin - Import devices directly from the PiHole database
Check out other [plugins](/docs/PLUGINS.md) that can help you discover more about your network or check how to scan [Remote networks](./REMOTE_NETWORKS.md).
NetAlertX supports additional plugins to extend its functionality, each with its own settings and options. Plugins can be loaded via the General -> `LOADED_PLUGINS` setting. For custom plugin development, refer to the [Plugin development guide](./PLUGINS_DEV.md).
>[!NOTE]
> Please check this [Plugins debugging guide](./DEBUG_PLUGINS.md) and the corresponding Plugin documentation in the below table if you are facing issues.
## ⚡ Quick start
> [!TIP]
> You can load additional Plugins via the General -> `LOADED_PLUGINS` setting. You need to save the settings for the new plugins to load (cache/page reload may be necessary).
1. Pick your `🔍 dev scanner` plugin (e.g. `ARPSCAN` or `NMAPDEV`), or import devices into the application with an `📥 importer` plugin. (See **Enabling plugins** below)
2. Pick a `▶️ publisher` plugin, if you want to send notifications. If you don't see a publisher you'd like to use, look at the [📚_publisher_apprise](/front/plugins/_publisher_apprise/) plugin which is a proxy for over 80 notification services.
3. Setup your [Network topology diagram](./NETWORK_TREE.md)
4. Fine-tune [Notifications](./NOTIFICATIONS.md)
5. Setup [Workflows](./WORKFLOWS.md)
6. [Backup your setup](./BACKUPS.md)
7. Contribute and [Create custom plugins](./PLUGINS_DEV.md)
## Plugin types
| Plugin type | Icon | Description | When to run | Required | Data source [?](./PLUGINS_DEV.md) |
| 🔄 | Has the option to sync some data back into the plugin source |
## Available Plugins
Device-detecting plugins insert values into the `CurrentScan` database table. The plugins that are not required are safe to ignore, however, it makes sense to have at least some device-detecting plugins enabled, such as `ARPSCAN` or `NMAPDEV`.
| ID | Plugin docs | Type | Description | Features | Required |
> \* The database cleanup plugin (`DBCLNP`) is not _required_ but the app will become unusable after a while if not executed.
> ❌ marked for removal/unmaintained - looking for help
> ⌚It's recommended to use the same schedule interval for all plugins responsible for discovering new devices.
## Enabling plugins
Plugins can be enabled via Settings, and can be disabled as needed.
1. Research which plugin you'd like to use, enable `DISCOVER_PLUGINS` and load the required plugins in Settings via the `LOADED_PLUGINS` setting.
1. Save the changes and review the Settings of the newly loaded plugins.
1. Change the `<prefix>_RUN` Setting to the recommended or custom value as per the documentation of the given setting
- If using `schedule` on a `🔍 dev scanner` plugin, make sure the schedules are the same across all `🔍 dev scanner` plugins
### Disabling, Unloading and Ignoring plugins
1. Change the `<prefix>_RUN` Setting to `disabled` if you want to disable the plugin, but keep the settings
1. If you want to speed up the application, you can unload the plugin by unselecting it in the `LOADED_PLUGINS` setting.
- Careful, once you save the Settings Unloaded plugin settings will be lost (old `app.conf` files are kept in the `/config` folder)
1. You can completely ignore plugins by placing a `ignore_plugin` file into the plugin directory. Ignored plugins won't show up in the `LOADED_PLUGINS` setting.

* Making the tables sortable/filterable
* Using the same approach to display table data as in the Devices section (solves above)
* Adding form controls supported to display the data (Currently supported ones are listed in the section "UI settings in database_column_definitions" below)

These issues will be hopefully fixed with time, so please don't report them. Instead, if you know how, feel free to investigate and submit a PR to fix the below. Keep the PRs small as it's easier to approve them:
* Existing plugin objects are sometimes not interpreted correctly and a new object is created instead, resulting in duplicate entries. (race condition?)
* Occasional (experienced twice) hanging of processing plugin script file.
* UI displays outdated values until the API endpoints get refreshed.

### UI Component Types Documentation
This section outlines the structure and types of UI components, primarily used to build HTML forms or interactive elements dynamically. Each UI component has a `"type"` which defines its structure, behavior, and rendering options.
#### UI Component JSON Structure
The UI component is defined as a JSON object containing a list of `elements`. Each element specifies how it should behave, with properties like `elementType`, `elementOptions`, and any associated `transformers` to modify the data. The example below demonstrates how a component with two elements (`span` and `select`) is structured:
The code snippet provided demonstrates how the elements are iterated over to generate their corresponding HTML. Depending on the `elementType`, different HTML tags (like `<select>`, `<input>`, `<textarea>`, `<button>`, etc.) are created with the respective attributes such as `onChange`, `my-data-type`, and `class` based on the provided `elementOptions`. Events can also be attached to elements like buttons or select inputs.
### Key Element Types
- **`select`**: Renders a dropdown list. Additional options like `isMultiSelect` and event handlers (e.g., `onChange`) can be attached.
- **`input`**: Handles various types of input fields, including checkboxes, text, and others, with customizable attributes like `readOnly`, `placeholder`, etc.
- **`button`**: Generates clickable buttons with custom event handlers (`onClick`), icons, or labels.
- **`textarea`**: Creates a multi-line input box for text input.
- **`span`**: Used for inline text or content with customizable classes and data attributes.
Each element may also have associated events (e.g., running a scan or triggering a notification) defined under `Events`.
##### Supported settings `function` values

By design, local network scanners such as `arp-scan` use ARP (Address Resolution Protocol) to map IP addresses to MAC addresses on the local network. Since ARP operates at Layer 2 (Data Link Layer), it typically works only within a single broadcast domain, usually limited to a single router or network segment.
> [!NOTE]
> Ping and `ARPSCAN` use different protocols so even if you can ping devices it doesn't mean `ARPSCAN` can detect them.
To scan multiple locally accessible network segments, add them as subnets according to the [subnets](./SUBNETS.md) documentation. If `ARPSCAN` is not suitable for your setup, read on.
## Complex Use Cases
The following network setups might make some devices undetectable with `ARPSCAN`. Check the specific setup to understand the cause and find potential workarounds to report on these devices.
### Wi-Fi Extenders
Wi-Fi extenders typically create a separate network or subnet, which can prevent network scanning tools like `arp-scan` from detecting devices behind the extender.
> **Possible workaround**: Scan the specific subnet that the extender uses, if it is separate from the main network.
### VPNs
ARP operates at Layer 2 (Data Link Layer) and works only within a local area network (LAN). VPNs, which operate at Layer 3 (Network Layer), route traffic between networks, preventing ARP requests from discovering devices outside the local network.
VPNs use virtual interfaces (e.g., `tun0`, `tap0`) to encapsulate traffic, bypassing ARP-based discovery. Additionally, many VPNs use NAT, which masks individual devices behind a shared IP address.
> **Possible workaround**: Configure the VPN to bridge networks instead of routing to enable ARP, though this depends on the VPN setup and security requirements.
# Other Workarounds
The following workarounds should work for most complex network setups.
## Supplementing Plugins
You can use supplementary plugins that employ alternate methods. Protocols used by the `SNMPDSC` or `DHCPLSS` plugins are widely supported on different routers and can be effective as workarounds. Check the [plugins list](./PLUGINS.md) to find a plugin that works with your router and network setup.
## Multiple NetAlertX Instances
If you have servers in different networks, you can set up separate NetAlertX instances on those subnets and synchronize the results into one instance using the [`SYNC` plugin](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/sync).
## Manual Entry
If you don't need to discover new devices and only need to report on their status (`online`, `offline`, `down`), you can manually enter devices and check their status using the [`ICMP` plugin](https://github.com/jokob-sk/NetAlertX/blob/main/front/plugins/icmp_scan/), which uses the `ping` command internally.
For more information on how to add devices manually (or dummy devices), refer to the [Device Management](./DEVICE_MANAGEMENT.md) documentation.
To create truly dummy devices, you can use a loopback IP address (e.g., `0.0.0.0` or `127.0.0.1`) so they appear online.
## NMAP and Fake MAC Addresses
Scanning remote networks with NMAP is possible (via the `NMAPDEV` plugin), but since it cannot retrieve the MAC address, you need to enable the `NMAPDEV_FAKE_MAC` setting. This will generate a fake MAC address based on the IP address, allowing you to track devices. However, this can lead to inconsistencies, especially if the IP address changes or a previously logged device is rediscovered. If this setting is disabled, only the IP address will be discovered, and devices with missing MAC addresses will be skipped.
Check the [NMAPDEV plugin](https://github.com/jokob-sk/NetAlertX/tree/main/front/plugins/nmap_dev_scan) for details
If you are running a DNS server, such as **AdGuard**, set up **Private reverse DNS servers** for a better name resolution on your network. Enabling this setting will enable NetAlertX to execute dig and nslookup commands to automatically resolve device names based on their IP addresses.

> Before proceeding, ensure that [name resolution plugins](./NAME_RESOLUTION.md) are enabled.

NetAlertX provides powerful tools for network scanning, presence detection, and automation. However, **it is up to you—the deployer—to ensure that your instance is properly secured**.
This includes (but is not limited to):
- Controlling who has access to the UI and API
- Following network and container security best practices
- Running NetAlertX only on networks where you have legal authorization
- Keeping your deployment up to date with the latest patches
> NetAlertX is not responsible for misuse, misconfiguration, or unsecure deployments. Always test and secure your setup before exposing it to the outside world.
# 🔐 Securing Your NetAlertX Instance
NetAlertX is a powerful network scanning and automation framework. With that power comes responsibility. **It is your responsibility to secure your deployment**, especially if you're running it outside a trusted local environment.
---
## ⚠️ TL;DR – Key Security Recommendations
- ✅ **NEVER expose NetAlertX directly to the internet without protection**
- ✅ Use a **VPN or Tailscale** to access remotely
- ✅ Enable **password protection** for the web UI
- ✅ Harden your container environment (e.g., no unnecessary privileges)
- ✅ Use **firewalls and IP whitelisting**
- ✅ Keep the software **updated**
- ✅ Limit the scope of **plugins and API keys**
---
## 🔗 Access Control with VPN (or Tailscale)
NetAlertX is designed to be run on **private LANs**, not the open internet.
**Recommended**: Use a VPN to access NetAlertX from remote locations.
### ✅ Tailscale (Easy VPN Alternative)
Tailscale sets up a private mesh network between your devices. It's fast to configure and ideal for NetAlertX.
👉 [Get started with Tailscale](https://tailscale.com/)
---
## 🔑 Web UI Password Protection
By default, NetAlertX does **not** require login. Before exposing the UI in any way:
1. Enable password protection:
```ini
SETPWD_enable_password=true
SETPWD_password=your_secure_password
```
2. Passwords are stored as SHA256 hashes
3. Default password (if not changed): 123456 — change it ASAP!
> To disable authenticated login, set `SETPWD_enable_password=false` in `app.conf`
---
## 🔥 Additional Security Measures
- **Firewall / Network Rules**
Restrict UI/API access to trusted IPs only.
- **Limit Docker Capabilities**
Avoid `--privileged`. Use `--cap-add=NET_RAW` and others **only if required** by your scan method.
- **Keep NetAlertX Updated**
Regular updates contain bug fixes and security patches.
- **Plugin Permissions**
Disable unused plugins. Only install from trusted sources.
- **Use Read-Only API Keys**
When integrating NetAlertX with other tools, scope keys tightly.
---
## 🧱 Docker Hardening Tips
- Use `read-only` mount options where possible (`:ro`)
- Avoid running as `root` unless absolutely necessary
- Consider using `docker scan` or other container image vulnerability scanners
- Run with `--network host` **only on trusted networks** and only if needed for ARP-based scans

- **Editability:** Uneditable (auto-detected).
- **Source:** Automatically captured when the device is first added to the system.
2.**Date and Time of Last Connection**
- **Description:** Shows the most recent time the device was online.
- **Editability:** Uneditable (auto-detected).
- **Source:** Updated with every new connection event.
3.**Offline Devices with Missing or Conflicting Data**
- **Description:** Handles cases where a device is offline but has incomplete or conflicting session data (e.g., missing start times).
- **Handling:** The system flags these cases for review and attempts to infer missing details.
---
## How Sessions are Discovered and Calculated
### 1. Detecting New Devices
When a device is first detected in the network, the system logs it in the events table:
`INSERT INTO Events (eve_MAC, eve_IP, eve_DateTime, eve_EventType, eve_AdditionalInfo, eve_PendingAlertEmail) SELECT cur_MAC, cur_IP, '{startTime}', 'New Device', cur_Vendor, 1 FROM CurrentScan WHERE NOT EXISTS (SELECT 1 FROM Devices WHERE devMac = cur_MAC)`
- Devices scanned in the current cycle (**CurrentScan**) are checked against the **Devices** table.
- If a device is new:
- A **New Device** event is logged.
- The device’s MAC, IP, vendor, and detection time are recorded.
### 2. Logging Connection Sessions
When a new connection is detected, the system creates a session record:
`INSERT INTO Sessions (ses_MAC, ses_IP, ses_EventTypeConnection, ses_DateTimeConnection, ses_EventTypeDisconnection, ses_DateTimeDisconnection, ses_StillConnected, ses_AdditionalInfo) SELECT cur_MAC, cur_IP, 'Connected', '{startTime}', NULL, NULL, 1, cur_Vendor FROM CurrentScan WHERE NOT EXISTS (SELECT 1 FROM Sessions WHERE ses_MAC = cur_MAC)`
- A new session is logged in the **Sessions** table if no prior session exists.
- Fields like `MAC`, `IP`, `Connection Type`, and `Connection Time` are populated.
- The `Still Connected` flag is set to `1` (active connection).
### 3. Handling Missing or Conflicting Data
- Devices with incomplete or conflicting session data (e.g., missing start times) are detected.
- The system flags these records and attempts corrections by inferring details from available data.
### 4. Updating Sessions
- When a device reconnects, its session is updated with a new connection timestamp.
- When a device disconnects:
- The **Disconnection Time** is recorded.
- The `Still Connected` flag is set to `0`.
The session information is then used to display the device presence under **Monitoring** -> **Presence**.

## Explanation
### Network mask
### Network Mask
**Example value:`192.168.1.0/24`**
**Example value:** `192.168.1.0/24`
The arp-scan time itself depends on the number of IP addresses to check.
The `arp-scan` time itself depends on the number of IP addresses to check.
> The number of IPs to check depends on the [network mask](https://www.calculator.net/ip-subnet-calculator.html) you set on the `SCAN_SUBNETS` setting.
> For example, a `/24` mask results in 256 IPs to check, whereas a `/16` mask checks around 65,536. Every IP takes a couple of seconds. This means that with an incorrect configuration, the arp-scan will take hours to complete instead of seconds.

Specify the network filter (which **significantly** speeds up the scan process). For example, the filter `192.168.1.0/24` covers IP ranges `192.168.1.0` to `192.168.1.255`.

### Network interface (adapter)
### Network Interface (Adapter)
**Example value:`--interface=eth0`**

### VLANs
**Example value: `-vlan=107`**
**Example value:**`--vlan=107`
- Append e.g.:`-vlan=107` to the interface field (e.g.: `eth0 -vlan=107`) for multiple vlans. More details in this [comment in this issue](https://github.com/jokob-sk/NetAlertX/issues/170#issuecomment-1419902988)

#### VLANs on a Hyper-V Setup
> Community-sourced content by [mscreations](https://github.com/mscreations) from this [discussion](https://github.com/jokob-sk/NetAlertX/discussions/404).
**Tested Setup:** Bare Metal → Hyper-V on Win Server 2019 → Ubuntu 22.04 VM → Docker → NetAlertX.
**Approach 1 (may cause issues):**
Configure multiple network adapters in Hyper-V with distinct VLANs connected to each one using Hyper-V's network setup. However, this action can potentially lead to the Docker host's inability to handle network traffic correctly. This might interfere with other applications such as Authentik.
**Approach 2 (working example):**
Network connections to switches are configured as trunk and allow all VLANs access to the server.
By default, Hyper-V only allows untagged packets through to the VM interface, blocking VLAN-tagged packets. To fix this, follow these steps:
1. Run the following command in PowerShell on the Hyper-V machine:
```powershell
Set-VMNetworkAdapterVlan -VMName <Docker VM Name> -Trunk -NativeVlanId 0 -AllowedVlanIdList "<comma separated list of vlans>"
```
#### VLANs on a Hyper-V setup
2. Within the VM, set up sub-interfaces for each VLAN to enable scanning. On Ubuntu 22.04, Netplan can be used. In /etc/netplan/00-installer-config.yaml, add VLAN definitions:
> Community sourced content by [mscreations](https://github.com/mscreations) from this [discussion](https://github.com/jokob-sk/NetAlertX/discussions/404).

dhcp4: yes
vlans:

id: 2
link: eth0
addresses: [ "192.168.2.2/24" ]
routes:
- to: 192.168.2.0/24
via: 192.168.1.1
```
> [!NOTE]
> The setup this was tested on: Bare Metal -> Hyper-V on Win Server 2019 -> Ubuntu 22.04 VM -> Docker -> NetAlertX.
3. Run `sudo netplan apply` to activate the interfaces for scanning in NetAlertX.
**Approach 1 (may cause issues):**
In this case, use `192.168.2.0/24 --interface=eth0.2` in NetAlertX.
Configure multiple network adapters in Hyper-V with distinct VLANs connected to each one using Hyper-V's network setup. However, this action can potentially lead to the Docker host's inability to handle network traffic correctly. The issue may stem from the creation of routes for network time servers or domain controllers on every interface, thereby preventing proper synchronization of the underlying Ubuntu VM. This interference can affect the performance of other applications such as Authentik.
#### VLAN Support & Exceptions
**Approach 2 (working example)**
Network connections to switches are configured as trunk and allow all VLANs access to the server.
By default Hyper-V only allows untagged packets through to the VM interface and no VLAN tagged packets get through. In order to fix this follow these steps:
1) Run the following command in Powershell on the Hyper-V machine:
```shell
Set-VMNetworkAdapterVlan -VMName <Docker VM Name> -Trunk -NativeVlanId 0 -AllowedVlanIdList "<comma separated list of vlans>"
```
(There might be other ways how adjust this.)
2) Within the VM, set up sub-interfaces for each of the VLANs so they can be scanned. On Ubuntu 22.04 Netplan can be used.
In /etc/netplan/00-installer-config.yaml, add vlan definitions:
```
network:
ethernets:
eth0:
dhcp4: yes
vlans:
eth0.2:
id: 2
link: eth0
addresses: [ "192.168.2.2/24" ]
routes:
- to: 192.168.2.0/24
via: 192.168.1.1
```
3) Run `sudo netplan apply` and the interfaces are then available to scan in NetAlertX.
4) In this case, use `192.168.2.0/24 --interface=eth0.2` in NetAlertX

> For versions prior to `v25.6.7` upgrade to version `v25.5.24` first (`docker pull ghcr.io/jokob-sk/netalertx:25.5.24`) as later versions don't support a full upgrade. Alternatively, devices and settings can be migrated manually, e.g. via [CSV import](./DEVICES_BULK_EDITING.md).
This guide outlines approaches for updating Docker containers, usually when upgrading to a newer version of NetAlertX. Each method offers different benefits depending on the situation. Here are the methods:
- Manual: Direct commands to stop, remove, and rebuild containers.
- Dockcheck: Semi-automated with more control, suited for bulk updates.
- Watchtower: Fully automated, runs continuously to check and update containers.
- Portainer: Manual with UI.
You can choose any approach that fits your workflow.
> In the examples I assume that the container name is `netalertx` and the image name is `netalertx` as well.
> [!NOTE]
> See also [Backup strategies](./BACKUPS.md) to be on the safe side.
## 1. Manual Updates
Use this method when you need precise control over a single container or when dealing with a broken container that needs immediate attention.
Example Commands
To manually update the `netalertx` container, stop it, delete it, remove the old image, and start a fresh one with `docker-compose`.
```bash
# Stop the container
sudo docker container stop netalertx
# Remove the container
sudo docker container rm netalertx
# Remove the old image
sudo docker image rm netalertx
# Pull and start a new container
sudo docker-compose up -d
```
### Alternative: Force Pull with Docker Compose
You can also use `--pull always` to ensure Docker pulls the latest image before starting the container:
```bash
sudo docker-compose up --pull always -d
```
## 2. Dockcheck for Bulk Container Updates
Always check the [Dockcheck](https://github.com/mag37/dockcheck) docs if encountering issues with the guide below.
Dockcheck is a useful tool if you have multiple containers to update and some flexibility for handling potential issues that might arise during mass updates. Dockcheck allows you to inspect each container and decide when to update.
### Example Workflow with Dockcheck
You might use Dockcheck to:
- Inspect container versions.
- Pull the latest images in bulk.
- Apply updates selectively.
Dockcheck can help streamline bulk updates, especially if you’re managing multiple containers.
Below is a script I use to run an update of the Dockcheck script and start a check for new containers:
Always check the [watchtower](https://github.com/containrrr/watchtower) docs if encountering issues with the guide below.
Watchtower monitors your Docker containers and automatically updates them when new images are available. This is ideal for ongoing updates without manual intervention.
### Setting Up Watchtower
#### 1. Pull the Watchtower Image:
```bash
docker pull containrrr/watchtower
```
#### 2. Run Watchtower to update all images:
```bash
docker run -d \
--name watchtower \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--interval 300# Check for updates every 5 minutes
```
#### 3. Run Watchtower to update only NetAlertX:
You can specify which containers to monitor by listing them. For example, to monitor netalertx only:
```bash
docker run -d \
--name watchtower \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower netalertx
```
## 4. Portainer controlled image
This assumes you're using Portainer to manage Docker (or Docker Swarm) and want to pull the latest version of an image and redeploy the container.
> [!NOTE]
> * Portainer does **not auto-update** containers. For automation, use **Watchtower** or similar tools.
> * Make sure you have the [persistent volumes mounted or backups ready](BACKUPS.md) before recreating.
### 4.1 Steps to Update an Image in Portainer (Standalone Docker)
1.**Login to Portainer.**
2. Go to **"Containers"** in the left sidebar.
3. Find the container you want to update, click its name.
4. Click **"Recreate"** (top right).
5.**Tick**: _Pull latest image_ (this ensures Portainer fetches the newest version from Docker Hub or your registry).
6. Click **"Recreate"** again.
7. Wait for the container to be stopped, removed, and recreated with the updated image.
### 4.2 For Docker Swarm Services
If you're using Docker Swarm (under **"Stacks"** or **"Services"**):
1. Go to **"Stacks"**.
2. Select the stack managing the container.
3. Click **"Editor"** (or "Update the Stack").
4. Add a version tag or use `:latest` if your image tag is `latest` (not recommended for production).
5. Click **"Update the Stack"**. ⚠ Portainer will not pull the new image unless the tag changes OR the stack is forced to recreate.
6. If image tag hasn't changed, go to **"Services"**, find the service, and click **"Force Update"**.

## How does the signing work?
NetAlertX will use the configured secret to create a hash signature of the request body. This SHA256-HMAC signature will appear in the `X-Webhook-Signature` header of each request to the webhook target URL. You can use the value of this header to validate the request was sent by NetAlertX.
Check for browser console (F12 browser dev console) errors + check different browsers.
### 3. Clear the app cache and cached JavaScript files
Refresh the browser cache (usually shoft + refresh), try a private window, or different browsers. Please also refresh the app cache by clicking the 🔃 (reload) button in the header of the application.
### 4. Disable proxies
If you have any reverse proxy or similar, try disabling it.
### 5. Disable your firewall
If you are using a firewall, try to temporarily disabling it.
### 6. Post your docker start details
If you haven't, post your docker compose/run command.
### 7. Check for errors in your PHP/NGINX error logs
In the container execute and investigate:
`cat /var/log/nginx/error.log`
`cat /app/log/app.php_errors.log`
### 8. Make sure permissions are correct
> [!TIP]
> You can try to start the container without mapping the `/app/config` and `/app/db` dirs and if the UI shows up then the issue is most likely related to your file system permissions or file ownership.
Please read the [Permissions troubleshooting guide](./FILE_PERMISSIONS.md) and provide a screesnhot of the permissions and ownership in the `/app/db` and `app/config` directories.
The workflows module in allows to automate repetitive tasks, making network management more efficient. Whether you need to assign newly discovered devices to a specific Network Node, auto-group devices from a given vendor, unarchive a device if detected online, or automatically delete devices, this module provides the flexibility to tailor the automations to your needs.
Below are a few examples that demonstrate how this module can be used to simplify network management tasks.
## Updating Workflows
> [!NOTE]
> In order to apply a workflow change, you must first **Save** the changes and then reload the application by clicking **Restart server**.
## Workflow components
### Triggers

Triggers define the event that activates a workflow. They monitor changes to objects within the system, such as updates to devices or the insertion of new entries. When the specified event occurs, the workflow is executed.
> [!TIP]
> Workflows not running? Check the [Workflows debugging](./WORKFLOWS_DEBUGGING.md) guide how to troubleshoot triggers and conditions.
#### Example Trigger:
- **Object Type**: `Devices`
- **Event Type**: `update`
This trigger will activate when a `Device` object is updated.
Conditions determine whether a workflow should proceed based on certain criteria. These criteria can be set for specific fields, such as whether a device is from a certain vendor, or whether it is new or archived. You can combine conditions using logical operators (`AND`, `OR`).
> [!TIP]
> To better understand how to use specific Device fields, please read through the [Database overview](./DATABASE.md) guide.
#### Example Condition:
- **Logic**: `AND`
- **Field**: `devVendor`
- **Operator**: `contains` (case in-sensitive)
- **Value**: `Google`
This condition checks if the device's vendor is `Google`. The workflow will only proceed if the condition is true.
### Actions

Actions define the tasks that the workflow will perform once the conditions are met. Actions can include updating fields or deleting devices.
You can include multiple actions that should execute once the conditions are met.
#### Example Action:
- **Action Type**: `update_field`
- **Field**: `devIsNew`
- **Value**: `0`
This action updates the `devIsNew` field to `0`, marking the device as no longer new.
# Examples
You can find a couple of configuration examples in [Workflow Examples](WORKFLOW_EXAMPLES.md).
> [!TIP]
> Share your workflows in [Discord](https://discord.com/invite/NczTUTWyRr) or [GitHub Discussions](https://github.com/jokob-sk/NetAlertX/discussions).
> Before troubleshooting, please ensure you have [Debugging enabled](./DEBUG_TIPS.md).
Workflows are triggered by various events. These events are captured and listed in the _Integrations -> App Events_ section of the application.
## Troubleshooting triggers
> [!NOTE]
> Workflow events are processed once every 5 seconds. However, if a scan or other background tasks are running, this can cause a delay up to a few minutes.
If an event doesn't trigger a workflow as expected, check the _App Events_ section for the event. You can filter these by the ID of the device (`devMAC` or `devGUID`).
16:27:03 [WF] Event with GUID '13f0ce26-1835-4c48-ae03-cdaf38f328fe' triggered the workflow 'Location Change'
```
Note how one trigger executed, but the other didn't based on different `"event_type"` values. One is `"event_type": "insert"`, the other `"event_type": "update"`.
Given the Event is a update event (note `...['online'], ['update'], [None]...` in the event structure), the `"event_type": "insert"` trigger didn't execute.
Workflows in NetAlertX automate actions based on real-time events and conditions. Below are practical examples that demonstrate how to build automation using triggers, conditions, and actions.
## Example 1: Un-archive devices if detected online
This workflow automatically unarchives a device if it was previously archived but has now been detected as online.
### 📋 Use Case
Sometimes devices are manually archived (e.g., no longer expected on the network), but they reappear unexpectedly. This workflow reverses the archive status when such devices are detected during a scan.
### ⚙️ Workflow Configuration
```json
{
"name":"Un-archive devices if detected online",
"trigger":{
"object_type":"Devices",
"event_type":"update"
},
"conditions":[
{
"logic":"AND",
"conditions":[
{
"field":"devIsArchived",
"operator":"equals",
"value":"1"
},
{
"field":"devPresentLastScan",
"operator":"equals",
"value":"1"
}
]
}
],
"actions":[
{
"type":"update_field",
"field":"devIsArchived",
"value":"0"
}
],
"enabled":"Yes"
}
```
### 🔍 Explanation
- Trigger: Listens for updates to device records.
- Conditions:
-`devIsArchived` is `1` (archived).
-`devPresentLastScan` is `1` (device was detected in the latest scan).
- Action: Updates the device to set `devIsArchived` to `0` (unarchived).
### ✅ Result
Whenever a previously archived device shows up during a network scan, it will be automatically unarchived — allowing it to reappear in your device lists and dashboards.
Here is your updated version of **Example 2** and **Example 3**, fully aligned with the format and structure of **Example 1** for consistency and professionalism:

## Example 2: Assign Device to Network Node Based on IP
This workflow assigns newly added devices with IP addresses in the `192.168.1.*` range to a specific network node with MAC address `6c:6d:6d:6c:6c:6c`.
### 📋 Use Case
When new devices join your network, assigning them to the correct network node is important for accurate topology and grouping. This workflow ensures devices in a specific subnet are automatically linked to the intended node.
### ⚙️ Workflow Configuration
```json
{
"name":"Assign Device to Network Node Based on IP",
"trigger":{
"object_type":"Devices",
"event_type":"insert"
},
"conditions":[
{
"logic":"AND",
"conditions":[
{
"field":"devLastIP",
"operator":"contains",
"value":"192.168.1."
}
]
}
],
"actions":[
{
"type":"update_field",
"field":"devNetworkNode",
"value":"6c:6d:6d:6c:6c:6c"
}
],
"enabled":"Yes"
}
```
### 🔍 Explanation
* **Trigger**: Activates when a new device is added.
* Sets `devNetworkNode` to the specified MAC address.
### ✅ Result
New devices with IPs in the `192.168.1.*` subnet are automatically assigned to the correct network node, streamlining device organization and reducing manual work.

## Example 3: Mark Device as Not New and Delete If from Google Vendor
This workflow automatically marks newly detected Google devices as not new and deletes them immediately.
### 📋 Use Case
You may want to automatically clear out newly detected Google devices (such as Chromecast or Google Home) if they’re not needed in your device database. This workflow handles that clean-up automatically.
### ⚙️ Workflow Configuration
```json
{
"name":"Mark Device as Not New and Delete If from Google Vendor",
"trigger":{
"object_type":"Devices",
"event_type":"update"
},
"conditions":[
{
"logic":"AND",
"conditions":[
{
"field":"devVendor",
"operator":"contains",
"value":"Google"
},
{
"field":"devIsNew",
"operator":"equals",
"value":"1"
}
]
}
],
"actions":[
{
"type":"update_field",
"field":"devIsNew",
"value":"0"
},
{
"type":"delete_device"
}
],
"enabled":"Yes"
}
```
### 🔍 Explanation
* **Trigger**: Runs on device updates.
* **Conditions**:
* Vendor contains `Google`.
* Device is marked as new (`devIsNew` is `1`).
* **Actions**:
1. Set `devIsNew` to `0` (mark as not new).
2. Delete the device.
### ✅ Result
Any newly detected Google devices are cleaned up instantly — first marked as not new, then deleted — helping you avoid clutter in your device records.
