On this community forum you are speaking with other users like myself and community specialist's. Sorry we don't have the answer to your question.
Please leave feedback from the Google Home app as this is passed directly to the Google Nest team.

However, there have been no updates at all since then.
That was 10 months ago, it's funny 10 months ago I made a commitment to learning to fly just using my arms. I can say that the progress i have made in learning to fly matches the progress of the home app becoming on par with the Nest app.
Many of us purchased some of the new devices not knowing they would not work with the Nest app, were you aware there is a market for older nest devices? They go for a premium on ebay.
Really the money Google has it is a joke we are in this place right now.
