The following mappings are required
TuyaMCU 11,1 TuyaMCU 21,2
and dimmer limits
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 :(
