Same here. Knocks on the door are rarely heard becaise of the layour of
the house, but the doorbell sounds in any room (and optionally in the
garden).

Or, or course some aid/adaptation to assist a deaf person.

I've got some odd, quite tight range PIR lights knocking around. Maybe a
winter project is a PIR doorbell substitute.

I was wondering about a vibration sensor on the door.



That rings a bell?
