The $50 D-Link Wi-Fi Smart Plug is a decent option if you're interested in basic home automation. Pair the plug with a lamp or other small appliance and use D-Link's free Android or iOS app to turn it on and off, set custom schedules, and monitor its energy usage. It's very similar to the $60 Belkin WeMo Insight Switch and the $50 Belkin WeMo Switch , except for one key difference: D-Link's version isn't compatible with IFTTT.
On the performance side, D-Link's Wi-Fi Smart Plug and app were both periodically glitchy during testing. While D-Link's Wi-Fi Smart Plug is OK at performing its functions, it doesn't seem like it can compete with the thoughtful dependability of Belkin's WeMo switches. I'd stick with Belkin even if IFTTT compatibility isn't on the top of your connected-home wish list.
This white, single-outlet plug measures 3.5 inches tall by 2.4 inches wide by 1.4 inches deep. It weighs 4.4 ounces and has a rectangular shape with rounded-off edges. It's rated for 100 to 125 volts of alternating current (VAC). That means that the outlet should be used to power lamps or other small appliances (large appliances have higher VAC requirements).
The Mydlink Smart Plug app works with Android 4.0 or higher and iOS 6 or higher on tablets and smartphones, and on Wi-Fi and cellular connections. It operates on a 2.4GHz Wi-Fi frequency and you can control up to 10 different Wi-Fi Smart Plugs at the same time using the app.
The $50 D-Link Wi-Fi Smart Plug fits into any three-prong electrical outlet on a wall or a power strip. Like a standard outlet, D-Link's plug is more functional than it is aesthetically compelling -- it probably won't be winning design awards anytime soon. It does blend into a two-outlet wall unit fairly seamlessly, and I'm guessing that was the intention.
But just when I was about to blame the blandness of traditional outlets for the blandness of this smart outlet, I started thinking about Dyson's vacuum cleaners and Nest's thermostats . Both companies have managed to make household objects into design statements rather than something you try to hide in a dark corner. They weren't satisfied with the uninspired design that dominates their appliance categories, so why should D-Link's plug look so plain?
