![[ZIGBEE] 20A Zigbee socket with energy metering (Tuya TS011F_plug_3)](https://obrazki.elektroda.pl/1000454900_1749493372_thumb.jpg)
The Enbrighten Plug-In Mini WiFi Smart Switch model WFD4103 is very well made device, its FCC certification can be found here.
It just has one button with a built-in LED.
The back plate is glued and can be separated by inserting a spudger, start from opposite edge where the the button is located.
The power pins are attached to the board but the ground pin comes out completely. This makes accessing the bottom of the chip very easy.
It uses a BK7231T WB2S module.
And can be flashed by using these 4 pins.
For initial flashing use the UA (UART) version of the firmware for BK7231T.
I used uartprogram for flashing.
To configure the module use:
* P7 = LED_n, channel=1
* P24 = Rel, channel=1
* P26 = Btn, channel=1
