I am trying to find a doorbell solution for a house that is split into two flats. The flats share one communal entrance door so I am thinking about putting two ring doorbells at the door (one for each flat). I would put a yale smart lock to be controlled by z wave so the tenants can buzz in their guests. Would this system work ? Is it possible for the one lock to be controlled from two different ring accounts ? If not is there a work around to make this work? Any help is very much apreciated!
