Hi, your problem may be cache issue.

Refer to this post about the same issue with the stock integration.

Official Google Nest Integration (January 2021)

After reaching out to Nest customer service via live chat, I was able to solve my own issue. If you don’t have some devices showing up in SmartThings that should, it’s most likely a cache issue on your phone. I was able to resolve the issue by restarting my Thermostat (by pressing it down for 10 seconds) and reinstalling the following apps: SmartThings, Nest, Google Home. Once I re-logged into each app and re-synced Nest with SmartThings, all of my devices appeared as expected. Hope this helps other people!

P. S. If you bought your tstat second hand, you might also have a tstat provided by an utility without knowing it.

That’s all I can think of at this point.

Regards.
