@FanMan 

what's the reasoning for that? Why are you so sure?

  @spacemancw because nobody has that need. I wonder if yours will work if you just keep the dimmer at 100%. But I'm not sure a dimmer is supposed to be on a motor.

  @FanMan So people have a need for a 4 speed smart ceiling fan switch with light dimmer, but no need for a three (or four) speed smart ceiling fan switch with light switch that's not dimable ?

The only difference is one is dimabale, one is not.  I agree, the motor for the oscilation should not be on a dimmer ... but I may work at 100% Any chance the dim function can be disabled in the app ?

  @spacemancw you can disable using the calibration. But I'm not certain max calibrated is 100% or if your motor will like it.
