Error spamming logs - AttributeError: 'cached_property' object has no attribute 'fget'

[thargy]

Type of problem

• [ ] I have a question.
• [ ] A feature does not work as expected.
• [x] I found a bug (see error log below).

Version

Encountered in 2.8.0, 2.9.0-beta.1. Also found in 2.5.1 from @FreshlyBrewedCode.

Detailed description

I noticed random system freezes where my Memory usage went over 91G (16G RAM) when it's usually ~10G max. I checked logs and noticed that errors from pymee and homee seemed to always occur as this happened. Reinstalled latest versions (see above), and re-configured homee from scratch (after in-place upgrade did not resolve anything). However, that didn't work either, and on clean start up I get the following in logs.

The logs then continue to span AttributeError: 'cached_property' object has no attribute 'fget' from File "/config/custom_components/homee/__init__.py", line 290, in state_attributes

I have confirmed that commenting out the property (Lines 287-297) not only fixes the log errors, but a bunch of entities that were missing/broken on my garage doors are now working again. I can't confirm whether the memory leak has gone, as it is intermittent, and may not be related to pymee/homee.

I could find no usage of the state_attributes property, nor homee_data attribute that got added to all entities as part of this commit; but you will probably want to review before just removing - hence I've not put in a PR.

Can confirm this worked for me, switches and sensors of my garage are back. Only my cover entity was present before. Thank you
