Thanks for letting us know you are interested in this feature.
We’re always trying to improve our user’s experience, but at this moment, viewing your Nest Thermostat on smart TV's isn't available. We're always looking for ways to improve and we'll take it as feedback. I suggest sending feedback on your Google Home app. Check this article for more information.
Let me know if I can assist with anything else, otherwise I’ll be locking this thread after 24 hours.
Sorry for the confusion. We hear you — we appreciate users who are keen on sharing with us their thoughts/experience. Keep sending your feedback as our Product Teams are continuously monitoring these reports. Please let us know if you have any other questions or concerns as I will be locking this in 24 hours.
