5 = dial anti-clockwise
6 = dial clockwise
held seems to work on all 4 buttons
Here's how I've set it up with the button controller for a Sonos speaker. Volume control is okay if you move the dial slowly. I guess there needs to be 2 extra commands, eg held = start raising volume, released = stop raising volume.
