First question:
Thinking of a door activated sensor for the attic bathroom as it will have
a fire door and I won't be passing to notice the light left on. Is this
possible? Not motion sensor only because my girls won't go in if the
light isn't on already. But it would need a motion sensor too so it
doesn't go dark while they are parked reading the Beano. Can't put a
motion senor outside the door as it is at the very top of the stairs and
would get triggered too often...

How about a push to operate time switch outside the door and a motion sensor
switch in the bathroom, wired in parallel? The girls could push the switch
before opening the door and, if they are still inside after the timer runs
out, the motion sensor should keep the light on.
