The sounder for my doorbell plugs into a mains socket, which gets
rid of part of the battery problem. However, because it is not
near the front door, and additionally the sound is produced when
the push is released, callers almost always knock as well.

Somebody recently remarked that it wasn't working, and I
demonstrated their error, commenting to them that I thought the
point was to put it where _I_ could hear it. The indicator light
flashes, but is clearly not trusted.

Good argument.

But surely the next step would be to have a door bell that sends an SMS
- and you can then be alerted on your mobile wheresoever you might be.
Ideally with the ability to make a voice call as well and thereby allow
some dialogue if you really are away. Obviously needs to be a limited
device so no-ones sees them as a way of getting a free mobile...
