I have 3 light switches that all control the same 2
lights, upstairs and downstairs hall lights. I believe this
is called a 4-way switch? I've looked around and have only seen a 3 way
X10 switch. Does anyone know of any X10 compatible 4-way switches out
there? Or have any suggestions how I can get these lights controlled by
Misterhouse, other than re-running the circuits and switches?
