I have been using the Nest E thermostat for 5 years solid, but Google screwed the API over. If I use my automation of in the UI to change the preset mode of turn it off or heat, it gives this message:
Perform action 'Climate: Set preset mode' on Kachel
Executed: October 21, 2025 at 23:26:43
Error: Error setting climate.kachel preset mode to eco: Bad Request response from API (400): FAILED_PRECONDITION (400): sdm.devices.commands.ThermostatEco.SetMode command not allowed in current thermostat mode.
I see in the documentation that:
The Nest Device Access Console Pub/Sub setup process has changed as of January 23rd 2025. Please make sure you are using the latest version of Home Assistant.
I am on the latest stable release of Home Assistant Core. If I look at the logs it seems to be a problem since yesterday afternoon. The usage of thermostats this autumn just started in the Netherlands, so maybe this issue have been over summer. Certainly not during last February/March.
I tried to find out what needs to be changed. I have no clue, since the Cloud Console is already a bit different than what the documentation says.
Is there anything I can do to get it working again? Or do I need to sell it and get a works with HA brand?
Thanks in advance!!
Kind regards,
