X 10, Leviton, Smart Home, might be compatible, even 3 button car
remotes and GMs can control X10, so you can turn on the coffee maker
from your car if you want.

I've set the sensor for my detached shop to turn on 2 floodlights and to
sound a 120 db warble siren. The system can be controlled from the house or
shop.
