The Zuli Smartplug Presence 3-Pack ($159.99) is a set of three plugs that turn your ordinary devices into smart ones. The Smartplugs let you control lights, televisions, and other appliances using your phone or tablet, and track how long those devices are active, how much carbon and energy they use, and how much that costs you. Using all three plugs via a proprietary mesh network, you can activate a feature that turns connected devices on or off automatically when you enter or leave a room. Unfortunately, the Smartplugs only work with iOS right now, and weren't able to dim some of the lights we used in testing. In addition, you're limited to Bluetooth range, so you can't control devices when you're out of the house. You'll get more bang for your buck with the Editors' Choice Belkin WeMo Insight Switch

Features
Each Smartplug measures 1.45 by 1.61 by 2.75 inches (HWD), weighs 3.24 ounces, and is made of smooth white plastic. There's a three-prong outlet on one side, a small manual On/Off button on the other side, and a hexagonal LED that blinks blue during setup and glows a steady blue when paired with your phone. Keep in mind the plug will add some bulk to your outlet, which could become an issue with furniture that is flush against the wall.
