It seems X10 can either be wireless or use your existing home electrical wiring to send signals to a control panel for home automation (lights etc.) or security (alarms, phone dialers etc.). This is ideal for me because I can always access my home wiring for installation of motion sensors etc. After some research, I'm having trouble finding a wall-mountable, X10 compatible motion sensor that isn't wireless. All the sensors I found use batteries and send a wireless signal to a X10 receiver. Does anyone know of a wired X10 motion sensor or is there some 110V module that will receive an input from a motion sensor and convert it to an X10 signal over your homes electrical wiring? Any ideas on how to do this would be greatly appreciated.
