THe answer to this is simple. Most door bell that don't work look like
they should work. therefore there is no way of telling if a bell is or
is not working.

Anybody who installs a doorbell that can't be heard to be working from
the door needs their head examining.

I must get professional help then :-)
If the bell can be heard from the door there is a reasonable chance that no
answer after 2 or 3 rings means that the house is empty; if the bell can't
be heard the caller has no information.

TBH if DG or other salesmen came round here I'd want a doorbell that
selectively didn't work.

Especially the last DGdroid: first question was if I owned or rented the
house. It seemed rather upset at my reaction to a personal financial
question.
