Hi. I'm trying to migrate my Nest Thermostat account to Google. When I go to nest app on thermostat their no passcode is showing it just says "already connected to an account". How do I get a new passcode?

Do you login to the Nest app using the "Sign in with Nest" link or the "Sign in with Google" button?

Hi. When I open Nest app it says 'add product'. I asks for QR Code on thermostat (no problem). It then asks for passcode. When I access Nest App on thermostat it says "already connected to account" with access to passcode available.

The reason I ask how you login is because that lets me know whether you're using a Nest account or Google account, as use of the Google Home app requires a Google account. If you didn't login to the Nest app using the "Sign in with Google" button, you'll need to first migrate your account.

If you're already using a Google account, or after migrating, when you install a Nest Learning Thermostat (1st, 2nd, or 3rd gen) or the Nest Thermostat E in the Nest app, the thermostat should automatically appear in the Google Home app if you’re using the same account in both apps, using the same home structure, and have assigned the thermostat to a room in the Nest app. If any of that isn’t true, you’ll need to go ahead and fix those issues.
If all of those things are true, try these steps:
This forces the two apps to sync and your thermostat should now appear in the Google Home app.
