I don't doubt such things can work but predictably? It really seems
like a technological step backward to me. I remember struggling with
various X-10 devices to control things via power line signaling in
the home. The device could be located near the controller but would
not work reliably unless on the same "phase" of the 120 system. The
signaling would not work unless powered by the same winding on the
main power transformer without additional equipment to couple the
signal across.
That was in Florida where lightning damage was a constant threat. I
wanted to control a solenoid operated valve at a well pump, it
worked initially but did not survive. Even here in Virginia I would
feel uneasy about creating a path from the power line to a signal
level input on the computer.
