Issue using voice commands on my Nest thermostat

[pastafan]

There seems to be an issue using my voice, to command the Nest thermostat to perform any action. Like "turn on the heating", "change the temperature", etc.

Controlling the Nest thermostat by using the Nest app (Android) works well.

Controlling the Nest thermostat by using the Google Home app (Android) works well as well.

Voice commands is failing; this has been working good for years.

I use following configuration:

Speaker: Google Smart speaker;

Google Home app:  v 3.23.1.3

Thermostat: Nest Thermostat E-1.1, Software 6.1-9

I have already reset the Nest Thermostat and re-installed it. Did not resolve the issue.

@pastafan , your ability to control the nest thermostat using your voice works through the Nest speakers and Google Home. Please verify that Google homes still has your nest speakers defined an attached to it. So your commands to go into the Google speaker and then to the Google Home app and from the Google Home app it controls the nest thermostat. Just double check your Google Home to make sure your nest speakers are still defined, if this is the case, you can also do the speaker from Google Home and reattach the speaker to Google Home

@CoolingWizard thanks for your reply.

I have double checked again and did some further analysis as well.

The issue is more specific now:

I can control the heating using my voice, by increasing/decreasing the temperature: voice command to do that results in Nest app and Google. Also, asking (using voice) what the current temperature setting is results in correct voice feedback from Google home/smart speaker.

The issue is specific that I cannot turn on/off the Nest thermostat (using voice). 

When I voice-command the heating to turn to state off ("Hey Google, turn off heating"), I get the result "It looks like this device has not been setup".

When I voice-command the heating to set to a new threshold (put heating on 22 degrees), it works as expected (both Nest app and Google app are set to new temperature).

Any new insights?

Thanks,

@pastafan , sometimes the word parser in the Google speaker can get confused. Try using the command “hey Google, turn the nest thermostat system mode to off.” In your command it is trying to figure out what device called “heating”. It finds no device called heating so it’s giving you that response to device hasn’t been set up.

@CoolingWizard Thanks again.

I just found out its even more specific: 

Voice commanding to set the heating to mode Eco, results in corresponding action (set the mode to eco)

Voice commanding to set the heating to mode "heating" results in corresponding action (set the running mode to heating (as long as target temperature > actual temperature).

Voice commanding to mode "on" or "off" still gets the "no device has been setup".

So it looks like some modus issue: setting it to Eco or heating works well. 

Which in fact is (almost) same as setting it to "on" or "off".

I can live with this, but the strange thing is voice commanding it to on / off mode used to work for years... Not changed any setup by myself.. (software updates were updated automatically).
