Doesn't X-10 all depend on radio transmissions.

X-10 sends its signals over the power wires. There is a "new" system (the
same folks that sell X-10 will also sell the new stuff) that uses RF.

I'm going to use that
to flash the porch light when the alarm goes off, but that's not
critical. If at all possible, I like to use hard-wired things.

Well, if the transmitter and receiver are on the same 120 volt circuit, it's
pretty reliable.

Come to think of it, turning the hall light on is not critical either!
