Nest SetMode command not allowed in current thermostat mode

[carleeno]

The problem

When sending a command to set the preset mode of a nest thermostat, and the thermostat is already in that mode, the action fails with the error:

Error setting HVAC mode: Error from API: 400: FAILED_PRECONDITION: sdm.devices.commands.ThermostatEco.SetMode command not allowed in current thermostat mode.: Bad Request

For example, when attempting to set preset mode to "none" while thermostat preset is already "none" (not eco) it will throw this error.
This causes any scripts/automations containing this action to stop execution, which is how I discovered the issue (a script wasn't completing other actions).

Hey there @allenporter, mind taking a look at this issue as it has been labeled with an integration (nest) you are listed as a code owner for? Thanks!

Thanks for the report. Can you include diagnostics information from when the failing service call is sent?

[carleeno]

sure where can I find that?

[carleeno]

Looking on the device page and log pages, I can't find diagnostics info/download. I'm still struggling with the new settings menu, and searching settings came up empty.

Also, for now I'll add some extra conditions to my automations to prevent them from attempting this step if the thermostat is already in the desired mode, to ensure the rest of the automation is able to continue. However typically it's not a problem to set a thermostat to a mode it's already in.

Found it!

I was able to reproduce the issue, thank you for the report.

In the mean time, you may be able to set a condition in your automation, for example, to workaround by checking that the current preset mode is not eco mode.

[dlgoodr]

can reproduce same, and confirm workaround.

makes scenes hard, though.

I'm running HASS Docker image "ghcr.io/home-assistant/home-assistant:stable", and I can confirm the same issue as well.

I started getting this error also on an automation that had been working fine for months. Adding a check for the mode prevents the error but I'm also having the problem that Home Assistant is apparently not able to read the current mode correctly sometimes. When my automation ran the last two days, I know that it was in eco mode. On Monday, it produced the error. Yesterday, I added the check but then it returned false when checking for eco mode.

[allenporter]

Have diagnostics data?

It looked to be tied to the Home/Away mode in Nest. When I tested yesterday, I was just manually turning eco mode on/off and then trying to toggle back through manually running the actions for my automation. That worked fine but if I set Nest to Away and that triggers eco mode, then I get the error if I try to turn off eco mode from HA. My Nest integration does not appear to be able to read the preset mode under any conditions, it always thinks it is set to none.

I'm assuming Nest/Google made an api change on the backend. I'm seeing this issue also on HA 2022.6.7.

[sjd17]

Well, the update removed the error but didn't solve the problem. I no longer get an error when I try to change out of eco mode, but it just does nothing. As before, if i manually set it to eco mode, it works fine. If eco mode is set because Nest changes from Home to Away (ether manually or automatically), then it will not stop eco mode.

[allenporter]

My impression is that is a neat API bug where it's not sending updates on that transition. I previously reported this to nest.
