Good afternoon. I wanted to share with you the experience of firmware wi fi extension cable IMPITER WiFi Smart Power Strip.

This is how it looks inside:

The extension cord is assembled on the basis of a chip BK7231T / WB3

On the chip itself, the pinout is as follows

In order not to solder the chip, here is an example of where to solder on the board

This is how you need to set up channels

Here is the json config:


{
  "vendor": "Tuya",
  "bDetailed": "0",
  "name": "WiFi Smart Power Strip",
  "model": "IMPITER",
  "chip": "BK7231T",
  "board": "WB3",
  "flags": "1024",
  "keywords": [

Thank you for submitting the device with full JSON template, giving already filled JSON template really saves some time.
Why do you solder goldpins to the WiFi module? Is it to save wires from cutting? Still, I think it's a bit more hard than just soldering wires.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Thanks. It's more convenient for me. I don't want to cut the wires. Sometimes I leave such contacts soldered to the chip. You never know when you will need direct access to the firmware.

Hello, I bought one but it was a chipset BK7231N so the configuration is not the same.
