Hi @bigbadwoolfe, unfortunately there is not a zwave or zigbee device that has fan control and light control all in one device. I wish there was.
In my case I was lucky and I had separate wall switches for the light and fan already there that I replaced with a GE dimmer device and GE’s new fan control device.
Here’s a discussion thread that may help you:
Also, do not use a regular dimmer with a ceiling fan.
