The mydlink Wi-Fi Smart Plug ($49.99), D-Link's first official connected home device, lets you control lamps, coffee makers, and other small electrical appliances from anywhere using your smartphone or tablet. Like Belkin's WeMo Insight Switch, the D-Link Smart Plug is an easy-to-install, app-controlled Wi-Fi switch with scheduling and power tracking capabilities. But unlike the Insight, it lacks some key features, including support for If This Then That (IFTTT) recipes and power cost estimates.

Design and Apps

Measuring 3.4 by 2.4 by 1.4 inches (HWD), the Smart Plug is considerably larger than the Insight, but doesn't block the lower socket of a two-socket power outlet. However, you may have trouble getting it to fit into a tight space, such as an outlet positioned directly below a kitchen cabinet. The plug is white and has a single three-pronged outlet on its face, along with a manual On/Off switch and a Wi-Fi status indicator that blinks orange during setup and glows a steady green when it is connected to your router. A Wi-Fi Protected Setup (WPS) button is mounted on the left side of the plug.
