@W-M-B Only the traceback at 2024-01-14 10:49:49.910 concerns this integration (and the follow-up error at .913).

[DarwinsBuddy]

@DarwinsBuddy is this a regression of #123 ?

Could be. I merged some old branches. Maybe I overlooked something. Bare with me

[DarwinsBuddy]

It seems that home assistant is monkey patching all _attr prefixed attributes by registering them as entity attributes and moving them into the pseudo private namespace __attr see https://github.com/home-assistant/core/blob/1cdfb06d7719175bbf5c90c6787c2596afe9c4e5/homeassistant/helpers/entity.py#L374

Since they were property annotated functions instead of real class properties, this didn't work.

Fixed and going to roll out a patch version :+1:

[DarwinsBuddy]

Thanks to all of you for reporting that so quickly. :heart:

[manolitto]

Thank you for fixing that so quickly! ❤️
