Oukitel P2, also know as Merisny P2, is a 16A rated WiFi controllable plug. It can be purchased for 12USD on Banggood. It is based on the ESP8266 MCU. Works flawlessly with the Tasmota firmware.
I recommend doing an inspection and applying solder where there are weak spots or blank tinned copper pads, e.g. on the left edge of the board the relay output can be a bit sparsely tinned.

Setup
Connect to the device over Wifi as any regular Tasmota device and configure the template to the following:
{"NAME":"Oukitel P2","GPIO":[0,0,52,0,0,0,0,0,0,17,0,21,0],"FLAG":1,"BASE":18}
It provides one ADC0 input, usage undefined at the moment.
