I went to x10 to get a remote control for my traffic signal and wound up ordering this. It hooks into the computer via a USB cable and now I can control 12 lights or appliances and my traffic light from wall switches, wireless wall switches, remote controls and my computer. I will never have a light left on after hopping into bed. Cost a little over $200
