How about one of the window burglar alarms sensors that uses a magnet
and reed switch?

Excellent idea - and not too conspicuous if mounted *under* the door. I
can't imagine why I didn't think of that, because I recently designed
some very effective LED drawer lights using exactly what you suggest. I
even know where to get the right sort of switches, with contacts that
*close* when the magnet is withdrawn (the opposite of what's needed for
alarm applications).

It might be a bit of a fiddle getting the range right but it's a very
promising idea. Thanks.
