I wrote a driver that works decently well. The dial is setup to be a dimmer/level value 0-100.
And the firmware I'm currently on, all the buttons work 1-4, but when you hold down a button, no matter what, the same data comes out of the device, so I've set that up as button 5-held for now.
I don't have a hue hub, so I can't update the firmware, but I will try to update it at my partners house this weekend to see if that fixes the held button issue.
Here's the driver
