Rebooted the Pi etc. but nothing seems to happen. Nothing shows up in ~/config/devices/dashboard, no known_devices.yaml file appears. No logs indicating any errors.
In some cases it can be that your device is not discovered. In that case let your phone scan for Bluetooth devices while you restart Home Assistant. Just hit Scan on your phone all the time until Home Assistant is fully restarted and the device should appear in known_devices.yaml .
This is an old thread but maybe someone will find it from searching as I did when looking for solutions.
What worked for me was to put the phone into pairing mode and that created the entry in known_devices.yaml. I did it differently for another phone I tested. I found the device name amd bluetooth MAC in Settings, About and just created the entry in known_devices manually,. Reboot HA.
I found that consider_home values less than 30 seconds caused the system to constantly cycle from Home to Not Home every few seconds. Using interval_seconds did not work at all (I tried 8 seconds for testing).
Configuration.yaml just has device_tracker: - platform: bluetooth_tracker
known_devices has Motorola_Fusion: (from About on phone) name: This is my phone (override if desired) mac: BT_30:xx:xx:xx:xx:xx (note BT_ prefix) consider_home : 90 (default is 180 seconds) track: true
Everything except the first line on each should be indented … does not show on here.
