My bathroom door doesn’t have a lock on it, it’s also a hollow cheap door so I don’t fancy trying to install a lock (rental).
I have managed to get presence detecting going, wasp method with motion sensor inside and the door sensor as well as a humidity sensor (think bath times etc). I was going to operate this in turning the hallway light red to indicated occupied, green for unoccupied.
Then…I remembered my other half is colour blind. He sees both of those colours as a shade of brown! I have no plug sockets in the hallway to operate a wall tablet etc.
Any ideas? I like automating things, choosing the difficult way out rather than buy a new door
