Unfortunately, the device doesn’t report that it supports a 4th speed (‘max’) to other integrations, so there’s not a meaningful way of distinguishing that it’s a 4-speed fan.
The 4 Speed Fan Not Show Max Speed thread has some additional background and details on the issue. We proposed a supportedFanSpeeds attribute to SmartThings, but didn’t get any traction from them on it.

Based on the snippet you provided above, I found the following DTH - is this the one you were referring to? Z-wave Fan Controller
Side note: It looks like the built-in
raiseFanSpeed()method doesn’t support the ‘Max’ (4) speed level as it caps out at 3 as the maximum speed and it doesn’t cycle back over to 0. And even though they defined amax()method, they don’t expose it for our use.
That probably leaves us with cycling through the numeric speeds in a rule. Tagging @James to see if he has any better ideas.
This should not be the case. Once the selector on the dimmer range is released, it should immediately attempt to send the command.
If you’re able to consistently reproduce that, I would be interested in hearing more details on how you reproduce it and on what device.
