My Tado integration has been unstable the last few weeks. Not certain which release might have caused it, but this is the error I get in the logs:-
File "/usr/src/homeassistant/homeassistant/components/tado/__init__.py", line 154, in async_unload_entry
When this error happens, all of the tado entities show as unavailable.
Error seems to happen every few hours, and sometimes about once a week.
Same here!
Also having this issue. Reloading the integration can’t be done, as this requires unloading, and unloading is the main issue.
I am also having this problem. Sometimes when I restart HA is does work for a few minutes.
Error in logifle: Error while executing automation automation.reload_tado_hal_voor: The config entry ‘XXXXX’ (tado) with entry_id ‘XXXXXX’ cannot be unloaded because it is in the non recoverable state ConfigEntryState.FAILED_UNLOAD
I noticed I had some duplicate entities, and reinstalled the integration and it seems to be stable at the moment, but I also cannot reload the integration using a rest command, I still get the failed to unload error at that point.
I haver reported the problem to Home Assistant: TADO integration stopped working - Failed to unload · Issue #124708 · home-assistant/core · GitHub
I have updated HA Core to 2024.9.0. The TADO integration is working again 
Unfortunately its not. Mine has been pretty stable recently, but the underlying issue is still there.
