Are you getting errors in the logs?
Nothing at all in the logs.
hmmm...your code looks good to me and you should at least get something in the logs when you change the master fan.
Do you have the debug logs disabled. I see a setting for that in your code.
Nope...they are enabled.
AH HA! Got it...
Didn't realize that I left the virtual fan on low. So, when I set it to low, it didn't recognize that as an "event".

This is the way it landed. Also added slave switches to control table/floor fans that are controlled by smart plugs. Not required of course. Go on with any speed off with off. Seems to work so far.

I can see the possibilities for this app. Looking forward to trying it out.
Here's the Parent that's necessary also.

So this will only work on the devices with drivers that have the fanControl capability and the setSpeed command?
I have some fans that do not utilize this functionality (yet), and they are not showing as selectable devices. So I figured this to be the case.
Yes, requires fanControl capability (I base that on looking at the code above).
That's because the virtual device that is controlling them is using the Fan Control capability only. You could add slave dimmers but you would then have to work in logic to translate the speed into the appropriate dimmer level. All my fans have the capability. But you're welcome to modify/update/change whatever you like. After all, this is based off @JasonJoel's Dimmer Sync app. 
(with appropriate credit in the code I might add).
I have three of the Hampton Bay fans that have the capability. I have two fans controlled by the Homeseer FC-200+ fan switch that does not support fancontrol or setSpeed out of the box. However, I am re-writing the driver to hopefully incorporate it.
It is my first driver and I am still trying to wrap my head around some of it, but I hope to have it available soon.

It isn't too bad adding the fanControl capability and speed attribute. I added it to the GE fan control driver last week. Feel free to look at that as a reference if you need to. The code is sloppy because I was in a hurry, but it works.

@JasonJoel, you're the reason I am doing it. I was trying to figure out how to do it and there was not much available. However, when you got your driver done, I kind of sort of figured most of it out.
In fact, when you see my driver, you will think some of it looks vaguely familiar
Good! Steal/re-use code whenever possible. No point in starting over from scratch on everything if someone else has done something close!
Here's something else crazy...guess what doesn't show up in Rule Machine under "Control Fans"....that's right, the HE built in Virtual Fan device! LMAO The Virtual Fan device can't even be used by a custom command because it doesn't have the Actuator capability!!! Boy, that was all a complete waste of time.
So, @bravenel I think I have three asks at this point:
- Add the Fan Control capability as a condition/trigger in RM
- Add whatever is necessary to get the virtual fan device to show up under control fans.
- Allow for selecting a specific speed under the control fans command in RM rather than just bump to the "next level".
Added Actuator Capability to Virtual Fan Device. This is necessary to use custom command to setSpeed in RM.
