The Belkin WeMo switch is a programmable, Wi-Fi-enabled power switch that plugs directly into your power outlet and in which you plug your mains-powered devices into. The Belkin Wi-Fi-enabled WeMo switch lets you turn electronic devices on or off from anywhere. The WeMo switch uses your existing home Wi-Fi network to provide wireless control of TVs, lamps, stereos, heaters, fans, and more.
