Bluetooth LE tracker not starting and not discovering new devices

[ProtoxiDe22]

The problem

Since quite some time, the bluetooth le tracking integration hasn't been working properly, i've tested this on my already working device and on a brand new homeassistant install (old installation is a rpi4, new installation is HAOS install on x86 nuc, so 2 very different platform with same result).

If no known_devices.yaml file is present, or no devices are set to tracked in the file, the integration just outright refuses to start, as per the logs i have put below.

If a tracked BLE device is present in the known_devices.yaml the integration seem to start properly, with no error at all in console, but no new devices are discorvered and written in the known_devices.yaml file,

If device is tracked by putting all the correct data in the known_devices.yaml file manually, the tracking seems to work properly

Any update?

I'm currently running HA 2023.8.3 on HAOS 10.5.

It's been broken for a long time. When known_devices.yaml is empty, I get the same log messages as @ProtoxiDe22 . When I restore my old known devices file, I don't get any message and I can see the devices in Home Assistant, but none of them are tracked.

E.g. configuration.yaml

  - platform: bluetooth_le_tracker
    interval_seconds: 30
    consider_home: 240
    new_device_defaults:
      track_new_devices: true

known_devices.yaml

...
tv_samsung_led50:
  icon: mdi:television
  mac: BLE_12:34:56:78:90:12
  name: '[TV]Samsung LED50'
  picture:
  track: true
...

Results in this entity

but it never gets home...

With the above config, when I run bluetoothctl from the console, I see a lot of activity without me actually starting a scan, which is probably the result of HA doing bluetooth scans. With passive scanning enabled in the bluetooth integration, I still see some bluetooth devices in bluetoothctl with starting a scan in it, so I guess that's bluetooth_le_tracker doing it's work ?

So I enabled debug logging for the bluetooth_le_tracker and it does add the devices from known_devices.yaml to the devices that need tracking, but that's the only output it ever outputs.

2023-08-21 17:48:36.784 DEBUG (MainThread) [homeassistant.components.bluetooth_le_tracker.device_tracker] Adding BLE_XXX to BLE tracker
2023-08-21 17:48:36.784 DEBUG (MainThread) [homeassistant.components.bluetooth_le_tracker.device_tracker] Adding BLE_XXX to BLE tracker

2023-08-21 17:48:36.784 DEBUG (MainThread) [homeassistant.components.bluetooth_le_tracker.device_tracker] Adding BLE_XXX to BLE tracker

Maybe I need to add some more debug logging to see what it's actually doing.

//update: So far I've got it working with the bluetooth integration set to passive scanning and manually calling scan le from bluetoothctrl. I also I set the scanning mode to PASSIVE in the callback registration.

    cancels = [
        bluetooth.async_register_callback(
            hass,
            _async_update_ble,
            BluetoothCallbackMatcher(
                connectable=False
            ),  # We will take data from any source
            bluetooth.BluetoothScanningMode.PASSIVE,
        ),
        async_track_time_interval(hass, _async_refresh_ble, interval),
    ]

It seems to me there's something wrong with the active scanning of the bluetooth integration. With passive scanning and running scan le I see this as output

With active scanning this is the output It only discovers 3 of my Hue lamps and I see them pop up in the logs of the bluetooth_le_track

2023-08-21 19:38:53.030 WARNING (MainThread) [custom_components.custom_bluetooth_le_tracker.device_tracker] See device: X - Hue Lamp
2023-08-21 19:38:53.032 WARNING (MainThread) [custom_components.custom_bluetooth_le_tracker.device_tracker] See device: Y - Hue Lamp
2023-08-21 19:38:53.033 WARNING (MainThread) [custom_components.custom_bluetooth_le_tracker.device_tracker] See device: Z - Hue Lamp

Very strange ...

//update2: in the screenshot you can also see a DEL event for my TV ... I didn't turn it off, it's strange that it doesn't see it anymore as soon as I enable active scanning (and stop scanning from bluetoothctrl using scan off).

I'm not really sure if something has already been fixed, but I've been running the dev branch locally on my desktop and the bluetooth_le tracker works fine for LE devices:

Non-LE devices might briefly show home when these devices were previously paired, after that they just go away forever.

I think in the past the bluetooth_le tracker also tracked non-LE devices and we were used to this working.

[kittenmcnuggets]

Mine seemed to not start or generate a known devices file. Then after I manually created one with a known working ble Mac, it would add it as an entity, but it did nothing and I have been unable to delete the entity even after removing the kd.yaml.

Same for me. Started when upgrading from HA Core 2023.3.6 to 2023.4.6. Worked perfectly before that update!

Is this maybe just a logger warning if the known_devices.yaml does not contain at least one device to track?

I think I might have changed that back then... but just an assumption.

Still an issue 2024.4.1. I've set up Bluetooth LE Tracker according to the documentation https://www.home-assistant.io/integrations/bluetooth_le_tracker/ There is no known_devices.yaml generated.
