This is off topic but sometimes I am sorta annoid that the standard for a doot is lock in door and hole in wall. I feel if the setup had the lock in the wall then it could be wired into the electric and you would not need batteries or such for an electric one. Maybe a recharchable one so it would work for awhile in a power outage.






Thats a good idea. It might even be able to be contactless. Then like you have a wire coming off the plate part in the wall and you just need a plug nearby.
