Description

after creating a BT with the TRV 801w, the new BT device is unavailable. If i do the configuration again, equal if i change something or not, the bt device is getting available. Until the HA has to be rebooted. After the reboot the bt device is unavailable forever. So the configuration hack won't work. Th only think is to delete it and create it new!

Steps to Reproduce

create BT device -> unavailable
do the configuration again -> available
reboot HA -> unavailable forever

Expected behavior:

BT device should be work from the beginning ;)

Actual behavior:

doesnt work from beginning

Versions

tested with 1.4.0, 1.5.0 - beta6, 1.5.0 - beta7 and 1.5.0

Additional Information

i tried some different TRV801w and some different external temperature sensor, always the same. The temperature sensors worked fine with some AVM 301, so the problem must be the TRV801w!
