Tado: Cannot control Tado Smart AC Control

The problem

I have a Tado Smart AC Control. I have disabled fallback mode.

Only two buttons on the Tado control in HA work - automatic schedule and power off.

All of the other controls do nothing (and changing the temperature does nothing). I have tested via the app and via my.tado.com. Controlling using these methods works as expected.

While the AC has been switched on using another method using the tado.set_climate_timer also does nothing when trying to change the temperature.

Thanks everyone for your logs! I will prepare a fix in the coming days, and as soon as we identify what is an expected behavior, I will add tests to the integration or to python-tado to prevent that from breaking again. I will probably try to keep most of the logic in python-tado as I think it’s better to keep the HA integration as lightweight as possible.

Stay tuned!

@fuzzysb thanks for the hint! I guess if /capabilities returns reliably what the API expects (e.g. your DRY mode must not send fanSpeed and/or temperature if I got it correctly), I should be capable of writing a test matrix that covers what should be sent and what should not based on available capabilities.

Do you have any other suggestions/advice to keep in mind while upgrading this integration? Thanks!
