Fan Controllers - Auto Mode - Does it really exist in ZWave controllers?

I'm working on adding fan control to a driver I'm developing. I am trying to figure out what to do with the setSpeed "auto" mode.

As far as I can see, there are no "real world" Z-Wave fan controllers with an "auto" mode -- is that correct, or does anybody know of one? I'm assuming the "auto" mode may just be from a controller for Zigbee or some other device. Can anybody confirm?

If that's the case, what are you supposed to do about "auto" - is there a way of removing it from the set of allowed enumerated values so that the "setSpeed" control on the web page doesn't display it? I suspect the answer is "no", but wanted to be sure.

I use the β€œAuto” mode to have Hubitat control the fan speed based on temperature and humidity (via a RM rule). If I want to control it myself, I take it off Auto.

Thanks. That's an interesting use!.

My question was meant to be a bit more specific - is there an "auto" mode in any Z-wave device fan controller device itself (as opposed to driver code implementing an auto mode by continually sending Z-wave commands to the device). If anybody knows that, answer, please let me know.

Z-Wave fan controllers use SwitchMultilevel Command Class witch is 0-99 value or 255 (last on value).

Yes, the Hampton Bay Zigbee Fan Controller does indeed have an "Auto" mode, which allows the fan controller to randomly vary the speed of the fan to create a more 'natural wind' style of experience. I am guessing that is the origin of the "Auto" mode in the Hubitat capability.
