Hmmm… interesting scenario. If @spen is correct (I’m honestly not sure – we’ve had this debate internally, but we’re not electricians, so I’m going to go with the evidence posted, which looks to be that it’s ok) then it should be possible using scene control.
For example:
- 2-1 Switch would control the canned lights via a wired connection
- 2-1 Switch could then use any of the buttons to trigger on/off or if the fan speed could be remotely controlled, you could even use a multi-tap to change speed
- On/Off = Tap Config Button 1x (toggles each time you press the button)
- Low = Tap Config Button 2x
- Med = Tap Config Button 3x
- High = Tap Config Button 3x
Here’s the full button pressing chart for reference (the above was just an example): 2-1 Switch Button Mapping
However, to answer your question regarding whether or not any of us have tested this, unfortunately we haven’t (I didn’t know ZigBee fans were a thing honestly lol). Can you point me in the direction of the fan you’re looking into and I can do some research? That’s actually pretty exciting.
