Just got this TV last week. Super bummed to hear my Google Home say that it can't turn on/off the Living Room TV, consult user manual. However asking it to play a nest cam or YouTube does turn the TV on.
Also, I can't seem to get the standard Chromecast home screen to respond to my album and temp settings in the Google home app.
Seems to me Chromecast Built-in is half baked and nowhere close to being as functional as a Chromecast ultra.
Rant over. Thank you.
Google can turn the TV off. You will have to configure it through Google home, then it will work. I have the 930 model and Android TV, and it works.
