D-Link, the maker of routers, cameras and other Wi-Fi gear is following rival Belkin into the smart home with a $50 connected plug. The smart plug may be a gateway into a connected home, but I’d like to see it come with extra sensors, presence awareness or energy consumption data. D-Link’s plug seems fine, offering a thermal sensor to shut off devices if they overheat and energy consumption data. I also like a Kickstarter that launched Tuesday for the SAM plug. That plug contains an array of sensors that make it a bit different.
