The wifi power plug makes use of your home wireless internet (so you'll need to have a WiFi router to use it). It's controlled using either an Apple or Android device, and you'll need the free app to make use of the system. Installing the system is as simple as plugging in the WiFi controlled power socket, installing the app on your device, then following the on-screen prompts to connect the plug to your router.
