Yes, but the standard plasticky ones *all* seem to be not waterproof.

Sure, but this is a DIY group.

I built the entire house from scratch on a bare block of land.

A bell push is quite a bit easier than that.

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.

Then you should make one yourself.

I could do, but I want an illuminated one. They only cost a few quid so
not worth the bother.
