Thanks for posting here in the Community. If you have two home structures on your Google Nest account and want to put them on one home structure, you have to delete one of the other home structures and then factory reset the Nest device to add them to a single home structure. Please take note before you delete your home to save all the videos from your Nest Camera or doorbell and verify that the one you're deleting doesn’t have an Active Nest-aware subscription. To share access to your Nest Camera, you can send an invite to a maximum of six people. Here is a link on how to share a home and devices in the Google Home app.
