Template for Tasmota v9.1+
{"NAME":"EDM-1WAA-EU","GPIO":[1,1,1,1,1,1,0,0,1,1,1,1,1,0],"FLAG":0,"BASE":54}

Once the template is applied, run the following commands to configure communication with the MCU: console Backlog SetOption97 1; TuyaMCU 11,1; TuyaMCU 21,2; DimmerRange 10,1000 3 The ESP talks to a secondary MCU at a different baud rate so that is why SetOption97 is required.

The Minimum dimmer range for the physical knob can be set with TuyaSend2 3,10

Tuya-Convert 2.3 was not possible for this device because the manufacturer started using newest Tuya firmware (tested on 2021-03-02).

The switch hardware version was updated (1.4) and is now shipped with the WB3S board, which makes the dimmer incompatible with tasmota and requires swapping the WB3S board with an ESP-12 board.

hardware rev 1.4

When replacing the WB3S with an ESP-12, make sure to connect GND and GPIO15 together.
