Tuya-Convert might not be possible for this device if the manufacturer started using newest Tuya firmware since this template was published (2020-01-07).

NOTICE!!! Manufacturer has started using unsupported non-ESP8266 chips recently and this device might not be compatible anymore.

The following mappings are required

TuyaMCU 11,1
TuyaMCU 21,2

and dimmer limits

DimmerRange 1,255

Worked fine with a 60 Watt resistive bulb. It meant to work with LED, but did flicker with a single 13 Watt load. Might meant a larger load.

Edit: Ordered 2x from Lighting Illusions (AU) in 08/2020 and both came with newer version of tuya firmware.
Attempted physical flash but GPIO-0 is not accessible due to the TYWE2S being sandwiched back to back with the adjacent PCB.
Destroyed both boards attempting to work around. Not recommended :(
