Nest integration complains of unsupported mode

Configuration
1

I have a custom automation that sets my thermostat. There are several triggers throughout the day. One of the modes it sets is hvac_mode to heat_cool. This has failed the last two nights with the error: Unsupported hvac_mode 'heat_cool'. When I set it manually from the Nest app it is set correctly. The next morning it accepts this same command (different temp values).

Any ideas why this is now failing and only at night? Feels like something on the Google side is rejecting/failing to accept the command from HA. Starting to think about abandoning Nest and choose something else that does not rely on cloud.

Same here. Gave up on modes and started setting temperatures explicitly. At least that bit works.

I have the same exact problem. The integration starts to break later in the day. It is not a Google API issue. It is an issue on the Home Assistant side. If you reload the integration, it will begin to work again.

When it is broken, the integration will show as “Off” with no other options. When it works, it has the normal HVAC modes.

I’ve seen this issue very intermittently in the past but it seems to be happening much more frequently. Running 2023.4.5 on HAOS 10.0 bare metal.

Update: I’ve created a new issue on github. See link.
