The X10 remote control system gives you an affordable way to automate your entire home. A hand-held remote sends a signal to a transceiver which is plugged into a wall outlet. The transceiver sends a signal through the house wiring to an appliance module, also plugged into a wall outlet. This module acts like a switch, turning on and off whatever is plugged into the module.
Multiple modules can be controlled from your remote control or from a timer.
The timer can be used to turn lights on and off, giving the appearance that someone is home.
