This board can be flashed with vanilla sonoff-tasmota. I used esptool on linux to upload the firmware.

Programming mode:

Short GPIO0 to GND, as with all boards.

If you have successfully put the micro into programming mode the LED does not light up!


Single Channel:

Works out of the box, configured as Sonoff Basic. The LED does not light up when the switch is turned off. Configure as Sonoff T1 to enable the LED.

Dual Channel:

{"NAME":"Wall Switch 2C","GPIO":[17,255,255,255,0,22,18,0,21,56,0,0,0],"FLAG":0,"BASE":28}

Triple Channel:

Since I don't own such a board, you are on your own...

Button 3 should be GPIO10 and Relay 3 should be GPIO4. Use at your own risk!
