If you’re moving to a new home and are a user of Apple’s Home app, you’ll probably want to set up and control your new home with your accessories. You can remove your home and manually reset your accessories. To delete your Home data:
Open Home and tap the Home tab.
Tap the arrow button.
Scroll to the bottom and tap Remove Home. Then tap Delete to confirm.
You might need to reset each of your accessories. To reset your accessory, look for a button on the accessory, check its manual, or contact the manufacturer.
