Nest Thermostat sometimes shows both Celsius and Farenheit

[jblackburn (James Blackburn)]

Hi,

I’m using the built-in Nest integration to control my Nest thermostats with automation. I am in the UK and my thermostats are in Celsius.

What’s weird is that I see that the thermostats start reporting in Farenheit on a daily basis. I think this is triggered by a built-in automation running against the Nest (I’ve got no custom apps currently).

Note temperature and heating temperature are out of sync in the screenshot:

If I re-discover GoogleNest devices, temperature reverts to Celsius.

Has anyone seen this bug / knows of a fix?
Many thanks

yes, a few others have reported similar issues. no fix at this time.

you can find several posts in the following thread…

Official Google Nest Integration (January 2021)

Has anyone seen when setting the Nest temp in a scene that the heat shows (for me) Fahrenheit but the cooling shows in Celsius? [image] [image] [image] [image] If I set heat and cool then it changes the 72F to 72C. I’m not sure if it really changes F to C but it displays that in the app. Why one in Fahrenheit and one in Celsius? I’m hoping this is a bug. I’d rather not have to convert to set a cooling temp.

do open a support ticket with St and google nest

I have the same issue… In my Nest automation, the cooling temperature randomly changed to Celcius while the heating temp stayed Fahrenheit. No luck with ST support so far. The Nest App and my SmartThings account are both set to fahrenheit.

Try switching to “Cool” mode briefly (with a high enough setpoint that the Thermostat will not actually run). That should trigger a report of the temperature scale for that mode, which should correct what you’re seeing within Routines and Scenes.

Thank you. I’ll try that and let you know.

That worked. Thank you.

Glad to hear that!
