Yes, but the standard plasticky ones *all* seem to be not waterproof.
I know, I've probably had about 6 or 7 go wrong in the last 10 years
or so. We've even got a canopy over our door.

Weather-proofing is not I think the main issue - It is over
enthusiastic button pushers. If they push the button and get no noise
as feedback, they tend to try again and push even harder.

There's that to it as well.

I was wondering about a small speaker above the door. On pressing the
button, the bells would sound in the house, but outside, a voice would
intone "The bell has been activated".

Or "Stop pressing the bloody bell! I'm coming!"

Seriously though, it's an idea or even just the sound of the bell
so the bell pusher can hear it.
