We can't see the mailbox from the house - it's down at the end of a

also be good to have at least a little warning before guests drop in.

Ideally, I'd like more than one sensor - one perhaps _inside_ the box,
so passing sheep, cattle and cats don't set it off, and one part-way up
the drive (above cat level), as a drop-in-guest-detector.

Wireless, of course, with a plug-in receiver.

Anyone here have useful experience of such things?

I have these:

Hooked up to a mixed X10/Insteon system.

The Luminite stuff is pretty good, but expensive (imo). Linking it into
Home Automation (HA) is initially simple, but becomes complex depending
on what you're trying to achieve.
