Steve, I like your idea a lot better! Also, this might be a way of getting the RF signal "inside" his home.A better approach would be to hook up a relay across the breaker and connect the relay contacts to a DS10A. When the power goes OFF it would trigger the DS10A by breaking the circuit.
Also, do you really want a GFCI on the pump motor circuit?
