Error in[homeassistant.components.device_tracker]

I realised I’ve got this error:

2019-06-18 08:12:30 ERROR (MainThread) [homeassistant.components.device_tracker] Error setting up platform legacy
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/bluetooth/", line 31, in discover_devices
    lookup_class=lookup_class, device_id=device_id)
_bluetooth.error: (110, 'Operation timed out')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/components/device_tracker/", line 76, in async_setup_legacy
    tracker.see, discovery_info)

bluetooth.btcommon.BluetoothError: error communicating with local bluetooth adapter

Could you help me understanding what is wrong?

Thank You


Please read the sticky post in the banner about how to help us help you.

However you’re running Home Assistant (, Hassbian, Docker, skateboard), it can’t reach the Bluetooth adaptor.

I have the same problem. Is there any advise you can share on how to fix this?

See the sticky post in the banner.
