Pi.Alert
WIFI / LAN intruder detector.
Scan the devices connected to your WIFI / LAN and alert you the connection of unknown devices. It also warns the disconnection of "always connected" devices.
(Apologies for my English and my limited knowledge of Python, php and
JavaScript)
optional Darkmode within this fork
How it works
The system continuously scans the network for:
- New devices
- New connections (re-connections)
- Disconnections
- "Always Connected" devices down
- Devices IP changes
- Internet IP address changes
Scan Methods
Up to three scanning methods are used:
- Method 1: arp-scan. The arp-scan system utility is used to search for devices on the network using arp frames.
- Method 2: Pi-hole. This method is optional and complementary to method 1. If the Pi-hole DNS server is active, Pi.Alert examines its activity looking for active devices using DNS that have not been detected by method 1.
- Method 3. dnsmasq. This method is optional and complementary to the previous methods. If the DHCP server dnsmasq is active, Pi.Alert examines the DHCP leases (addresses assigned) to find active devices that were not discovered by the other methods.
Components
The system consists of two parts:
Back
In charge of:
- Scan the network searching connected devices using the scanning methods described
- Store the information in the DB
- Report the changes detected by e-mail
- Optional speedtest for Device "Internet"

Front
A web frontal that allows:
- Manage the devices inventory and the characteristics
- Display in a visual way all the information collected by the back
- Sessions
- Connected devices
- Favorites
- Events
- Presence
- Concurrent devices
- Down alerts
- IP's
- manuel nmap scans
- Optional speedtest for Device "Internet"

With the work of jokob-sk/Pi.Alert and own extensions, the new maintenance page was added with various possibilities for maintenance and settings:
- Status Infos (active scans, database size, backup counter)
- Theme Selection (blue, red, green, yellow, black, purple)
- Language Selection (english, german, spanish)
- Light/Dark-Mode Switch
- Pause arp-scan
- DB maintenance tools
- DB Backup and Restore
Installation
Initially designed to run on a Raspberry Pi, probably it can run on many other Linux distributions.
