The mFi Outlet is a standard in-wall dual electrical outlet with Wi-Fi that features energy monitoring and can be independently controlled by an mFi Controller. The mFi Switch is an in-wall manageable switch/dimmer. In switch mode, it can be used to turn lights on and off. In dimmer mode, it can control incandescent, halogen, dimmable CFL, or dimmable LED lamps. Energy monitoring and controls are available in the mFi Controller.
