remote controlled light switch

X-10 and google

garage door opener type and google

If you want to "do it raht" so that both the existing switches in the garage operate "normally" and the remote also switches the light on or off.....

Sounds like you're going to need a DPDT "alternate position" relay wired into the existing 3-way switch travelers and a momentary rf switch to pulse its coil and cause the relay to act like a local DPDT switch that's just been flipped.

P.S. Can someone give me a good reason why they call those SPDT switches "3-way switches"? Seems to me they only have TWO positions.

My guess is they usually involve three devices, one lamp and two switches. Four way's add one or more switches. Maybe it is because the switches have three wires connected (four ways have four wires.)

A recent post somewhere said it goes back to the Edison days when 'openings' were counted for billing. A switch and a light were 2 openings or a 2-way. Two switches become a 3-way. 3 switches become a 4-way.

I forgot to mention on my last post about this that the light I want to control is a mercury vapor security light if that makes any difference.
