Moved into a home recently where the previous owner had left some motion sensors and door sensors on windows. But i cant seem to find a base station, i tried adding them in ring app, but could not add them (these devices are not showing up in ring app). I am attaching the pictures of these :
What do i need to make them work? Asked realtor to contact seller to remove them from their account. but anything else i can do to make them usable?
