The Belkin WeMo Switch lets you turn electronic devices on or off from anywhere inside--or outside--your home. The WeMo Switch uses your existing home Wi-Fi network to provide wireless control of TVs, lamps, stereos, and more. Simply download the free WeMo app, plug the switch into an outlet in your home, and plug any device into the switch. You'll be able to turn that device on or off using your smartphone or tablet. You can even set schedules for your devices and control them remotely using a mobile Internet connection. You can also add additional switches to your home to control more devices.
