Proper knob for smart dimmer

I use this on my sofa to turn the volume of my AVR, adjusting room brightness holding it down and turning, press to switch between light modes, and long hold to turn lights and AV equipment off. It has enough friction against the sofa itself to be operated without held down, and at least in my man-hands, can be operated both single-handed and two-handed comfortably. The plain shell it shipped with allows none of that properly except pressing it down.

The smaller half is 47mm diameter, the larger one is 55mm. Both are 18mm thick, so the unit is about 35-37+mm thick depending on how thick two-sided tape you used, or whether you opted for zero clearance with clue. This was the size I found comfortable grabbing, but it's "too nice" in the sense I end up fidgeting with it too.

The original device works fine (in command mode, not event mode, where it's basically just a button) in terms of a dimmer, but its ergonomy is near impossible to operate. Print with the flat sides down. When assembling, stick a piece of double-sided tape on each and stick them to the device.

The rear cover (that you attach the smaller knob to) must have its screw oriented with the hole, otherwise you can't remove it to replace the battery!

Hints of usage of the device itself: At least on my Home Assistant / Zigbee2MQTT setup, triple-clicking the button puts it in "command mode", where you lose the double-click function, but gain two distinct rotary values with the delta value. The device can send a 0-255 position too, but Zigbee2MQTT does not seem to expose it. When you:

• Rotate it, you get a brightness_step_up/down event with a numeric delta value of how far it turned since the last update

• Hold it down and rotate it, and you get a color_temperature_step_up/down event with a numeric delta value

• Press it without rotating, and you get a toggle event.

• Press and hold down for several seconds without turning it, and you get a hue_move event, and when you release it, you het a hue_stop event.
