Cannot add Leviton Fan Switch ZW4SF

Using a Zooz 800 Series stick which has worked great for other devices. But I cannot get this ZW4SF to add. Clicking add, then putting the switch in discover mode does nothing - times out. Pasting in the value for the QR code just adds it to a list of Unprovisioned devices. I’ve reset the switch. I’ve cut power to it. Nothing nada - only sadness. I need to control 5 other fans (6 total). This one was extra expensive at $54. So if there is some other similar fan control switch that I can add via Z-Wave, I’m open to that as well.

I have these fan controllers and they work.

The newer version Jasco 14314 works better and has infinite control of the fan vs just 3 speeds and reports status after switching on faster.

It’s possible you have a bad switch. I’d try factory resetting it again.
