![Device Details][screen1]


## Main Info
  - **MAC**: MAC addres of the device. Not editable.
  - **Name**: Friendly device name
  - **Owner**: Device owner (The list is self-populated with existing owners)
  - **Type**: Select a device type from the dropdown list (Smartphone, Table,
      Laptop, TV, router, ....) or type a new device type
  - **Vendor**: Automatically updated by Pi.Alert
  - **Favorite**: Mark the device as favorite and then it will appears at the
      begining of the device list
  - **Group**: Select a grouper ('Always on', 'Personal', Friends') or type
      your own Group name
  - **Comments**: Type any comments for the device

## Session Info
  - **Status**: Show device status : On-line / Off-Line
  - **First Session**: Date and time of the first connection
  - **Last Session**: Date and time of the last connection
  - **Last IP**: Last known IP used during the last connection
  - **Static IP**: Check this box to identify devices that always use the
      same IP

## Events & Alerts config
  - **Scan Cycle**: Select the scan cycle: 0, 1', 15'
    - Some devices do not respond to all ARP packets, for this cases is better
      to use a 15' cycle.
    - **For Apple devices I recommend using 15' cycle**
  - **Alert All Events**: Send a notification in each event (connection,
      disconnection, IP Changed, ...)
  - **Alert Down**: Send a notification when the device is down
    - *(Userful with "always connected" devices: Router, AP, Camera, Alexa,
      ...)*
  - **Skip repeated notifications during**: Do not send more than one
      notification to this device for X hours
    - *(Useful to avoid notification saturation on devices that frequently
      connects and disconnects)*

# Privacy & Random MAC's
<!--- --------------------------------------------------------------------- --->

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, Pi.Alert 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).
