Can’t connect 2nd phone to Nest

Community Member

My wife and I have installed the app and Google home app. She has incumbent to join the household. I want to add the Nest as a new device but it keeps saying get the code or scan it. I can’t do this as it has already been installed and that information is on the back of the unit. When trying to find the code using the unit it won’t do it as it says it is already connected (which it is but to my wife’s phone/app not mine).




If you and your wife are both members of the same Google Nest household, then you should both see the same Google Nest devices in your Google Nest "home". From your description, it sounds like you may NOT both be in the same Google Nest household, and you are trying to add a Nest thermostat in the Google Nest app and are being told your wife has already added the Nest thermostat.

You should not be trying to add devices separately in the Google Nest app (or the Google Home app) on each of your phones. Rather, if your wife created the Google Nest "home" and has already added the Nest thermostat there, she should send you an invitation to join her household and you should accept. Once you accept and join her household, you should see the Google Nest "home" with the Nest thermostat she has already installed.

See "Invite members to a home" in this Google Nest Help topic:

Thank you for replying. She has sent an invitation and I have accepted but this hasn’t added the thermostat.


Is the thermostat installed in the Google Nest "home" on your wife's phone?  If it is, and if you are logging onto the Google Nest app and Google Home app with the same Google account to which your wife sent the invitation, and you have selected that same "home" in the Google Nest app or the Google Home app on your phone, then you should see the same devices that she sees.

Maybe you need to log out and then log back on in the Google Nest app and Google Home app.

Great. Thank you
