Hello, maybe it is already possible, but I couldn’t find out how to :-}
I now have 4 smart locks around the house: front door, back door, garage and cellar - It would be very handy if I could set all 4 locks to close each time any one of them is set from open to lock. Then when I leave home for the day, I can just lock the door I am heading out from with confidence that all doors are secured at the same time : )
Cheers!
Mike.
