Adding Nest control to second IPad

[Rramjet]

I can’t get the Nest app to work on my Wife’s IPad. Works fine on mine. When I try to get the code from the app it says connected and no other options exist.

You won't be able to share access like that, that process is only for setup.

Your wife will need a Gmail/Google account or a Google account associated with the email address you invite.
