Using Tasmotizer

pip3 install --upgrade pip wheel
pip3 install tasmotizer
tasmotizer.py

Setup

From Console on Tasmota UI


Issue the following commands:

module 54
backlog so97 1 ; tuyamcu 11,1 ; tuyamcu 12,9 ; tuyamcu 21,10
backlog ledtable 0 ; dimmerrange 100,1000 ; so59 1 ; so68 0


Add the following rule, this should be all on ONE line. 

This rule will not turn the fan on when the fan speed is changed.

Rule1 on TuyaReceived#Data=55AA03070005030400010016 do publish2 stat/%topic%/speed 3,0 endon
      on TuyaReceived#Data=55AA03070005030400010117 do publish2 stat/%topic%/speed 3,1 endon
      on TuyaReceived#Data=55AA03070005030400010218 do publish2 stat/%topic%/speed 3,2 endon
      on TuyaReceived#Data=55AA03070005030400010319 do publish2 stat/%topic%/speed 3,3 endon


Enable the rule with the following

Even this doesn't work! Don't know why.

Issues

Flickering Light

I think this issue is a result of the triac not having proper adhesion to the heat sink. The triac is simply pushed up against the heatsink. It has a foam pad that allows heat transfer from the triac to the heatsink.



Could we do something better here?
