Konke Mini K and Mini Pro Wifi Smart Sockets are Based on ESP8266 SoC

ESP8266 WiFi modules are very popular in the maker community, but so far I have not seen it in any devices myself, until I saw a tweet from @EspressifSystem about a Mini K smart socket. A search on Aliexpress lead me to two devices made by Konke, who also made Kankun KK-SP3 WiFi socket, with Mini K and Mini Pro smart sockets.

Up to now, the device has been opened, found to run OpenWRT, and one the member wrote a Windows app to control the socket from a PC. It is a basic smart socket, without power monitoring capabilities, and unless you start hacking the hardware, all you can do is basically turn it on and off. The device is based on Qualcomm Atheros AR9931, found in many low cost routers supporting OpenWRT, and the socket indeed runs OpenWRT, which you can access via SSH or Telnet (username/password: root/admin).
