This tracker discovers new devices on boot and tracks bluetooth devices periodically based on interval_seconds value. It is not required to pair the devices with each other! Devices discovered are stored with 'bt_' as the prefix for device mac addresses in `known_devices.yaml`.
To use the Bluetooth tracker in your installation, add the following to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
device_tracker:
- platform: bluetooth_tracker
```
In some cases it can be that your device is not discovered. In that case let your phone scan for BT devices while you restart Home Assistant. Just hit `Scan` on your phone all the time until Home Assisstant is fully restarted and the device should appear in `known_devices.yaml`.
For additional configuration variables check the [Device tracker page](/components/device_tracker/).
