The SMJ GHOMA plug lets you turn electronic devices on or off from anywhere inside, or outside, your home. The adaptor uses your existing home Wi-Fi network to provide wireless control of TVs, lamps, stereos, and more. Simply download the free app available for both Android and iOS, 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 smart phone or pad device. You can even set timers 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. Built in security via the power button alerts uses when the power has been activated and messages can be customized within the app to PUSH through the app or be sent to an email address.
