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.

Any example of a 'door' switch and motion sensor in operation
together?

Thanks,
Suzanne.

I dont understand what youre trying to achieve, or to put it another
way, why you want a light rigged to the door.

I think she wants the light to come on and go off automatically while the
bathroom is occupied so that it cannot be left on accidentally.

To the OP: You probably need *two* switches wired in parallel - so that when
either or both are closed the light will be on. The first is the sort of
switch which is often used in stairwells in blocks of flats. It's a spring
loaded button rather than a toggle switch, plus a timer. When the button is
pressed, the light comes on and stays on for a pre-determined time - maybe
one minute. The second is a PIR (passive infra-red) switch as used on
outside lights etc. This needs to be inside the bathroom.

All you have then to do is the press the button before going into the
bathroom. The light will come on immediately and remain on for as long as
there is someone in the bathroom.
