Control the lights in your home from any room, or anywhere in the world, with theWeMo Light Switch ($50). This WiFi-enabled light switch replaces any standard light switch in your house or apartment, letting you turn lights on and off from your Android or iOS device. A quick project for the average DIYer — it’s easy to install and features a clip-on faceplate that fits flush against your wall. The app lets you program your lights to turn or off on a schedule, or at sunrise and sunset. A subtle backlight makes the light switch easy to locate, and IFTTT support connects it to a number of apps.
