Serious… a Nest Cam (battery) not showing up in the Nest App and being forced to use the Google Home app? Now I’ve heard it all - misleading consumers and faulty marketing to say the least! Google - fix this and integrate these cameras into the Nest App!
I hear you!
The battery camera (as you know already) is made for the Google Home app. Please send feedback directly. There is a link to do that in this blog post by Google GM.
I hope that that the Google Home app can replicate all of the features we use in the Nest app if more and more products are only using that app.
