TP-Link has added a smart power outlet to their lineup.
It replaces an existing outlet, communicates by WiFi and allows separate control of each of the two sockets. It provides a much cleaner installation than add-on plugs and support for it would be a great addition to the TP-Link line of devices.
It currently shows up as a KP200 with the name TP-LINK_Smart Plug_4C5C in the TP-Link Integration panel but only shows a control slider for one outlet. The slider always indicates “Off” even when the socket is on. Attempting to change the state will briefly indicate “On” then return to “Off.”
