I just signed up for a new nest account and an old home I had with nest several years ago shows up as my home. Likely it has to do with using the same g-mail account i have always used. How do I get my new home to show as my home?
Can't you just delete that old, unused "home" or "structure" in the Google Nest app or Google Home app, and then add a new "home"? If you get a Nest Aware subscription, you'll want to make sure you add it to the new "home" for your current residence.
