This tracker discovers new devices on boot and in regular intervals and tracks bluetooth low-energy devices periodically based on interval_seconds value. It is not required to pair the devices with each other!
|
|
Devices discovered are stored with 'BLE_' as the prefix for device mac addresses in `known_devices.yaml`.
|
|
|
|
<p class='note'>
|
|
Requires PyBluez. If you are on Raspbian, make sure you first install `bluetooth` and `libbluetooth-dev` by running `sudo apt install bluetooth libbluetooth-dev`
|
|
</p>
|
|
|
|
To use the Bluetooth tracker in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
device_tracker:
|
|
platform: bluetooth_le_tracker
|
|
```
|
|
|
|
As some BT LE devices change their MAC address regularly, a new device is only discovered when it has been seen 5 times.
|
|
Some BTLE devices (e.g. fitness trackers) are only visible to the devices that they are paired with. In this case, the BTLE tracker won't see this device.
|
|
|
|
BTLE tracking requires root privileges.
|
|
|
|
For running Home Assistant as non root user we can give python3 the missing capabilities to access the bluetooth stack. Quite like setting the setuid bit (see [Stack Exchange](http://unix.stackexchange.com/questions/96106/bluetooth-le-scan-as-non-root) for more information).
|
|
|
|
```bash
|
|
sudo apt-get install libcap2-bin
|
|
sudo setcap 'cap_net_raw,cap_net_admin+eip' `readlink -f \`which python3\``
|
|
```
|
|
|
|
A restart of Home Assistant is required.
