I think that requires actually connecting a physical dial to the GPIO pins on the Pi (which I could probably figure out) and then a bunch LINUX code magic, which I cannot 
I tried the PlugIn with the MS Surface Dial connected via BT but no joy.

Correct… a rotary encoder and the relevent componants connected to the GPIO pins.
No none of that is needed, all you have to do is configure the rotary encoder II plugin with the correct details.
Not 100% sure what you mean by this, but I have a external volume control that sits on the arm of my chair with a 1.2 meter cable running to my Volumio box with zero issues

Yeah not a big fan of these rotary encoders, I ended up using a BT remote.

The 1/2 watt resistors are a little excessive but they will do.
And ideally a 100nf capacitor between ground and each of the gpio’s. Just to make the action acurate and stable.
If you are also using the button on the rotary bear in mind there is no pull up resistor on the CYT1062’s for the switch.
That’s EXACTLY what I wanted to do. I got a Microsoft Surface Dial, got it connected to the device but couldn’t figure out where to go from there. Would what you have above work or does it need to be customized for each device?
Not the buttons, but yo need to find the events belonging to your dial.
All available keys can be found here:
Look at /dev/input/ and check the events while you press every combination of the thingy.
like:
cat /dev/input/event0
cat /dev/input/event1
cat /dev/input/event2
cat /dev/input/eventx
And add these events belonging to your thingy to the script.
Thanks… that level of code awareness is beyond me - I’m hardware guy with great Photo editing skills and zero coding ability. If I could hire someone to write it for me - that’s another skill
All you need to do is finding the events belonging to the dail.
And update the event numbers:
mousea = InputDevice('/dev/input/event0')
mouseb = InputDevice('/dev/input/event1')
mousec = InputDevice('/dev/input/event2')
moused = InputDevice('/dev/input/event3')
Since this depends on the USB port, what else is connected to the USB, you need to do this by yourself.
USB 2.0 ports going to 5.5 AMOLED touch screen and SMSL DAc
USB 3.0 ports going to external WiFi and External SSD
Does that matter since the Dial is BlueTooth?
please read:
You’re going to make me code, aren’t you? 
I already gave you the complete code all you have to do is get the proper events as instructed.
I get the impression your better in asking questions than in reading?
I literally have no idea what do with the code or how to “get” the events. I’ve read through it but it’s just a wall of text that assumes you understand the coding and instruction set.
Sorry to be a bother and you can go ahead and consider this closed - this has skill requirements above what I have or am willing to invest the time to learn so I’ll just another option for volume control.
I gave t-you the complete code, instructions what you need to do.
Since I don’t have the hardware, you do, this is on you to determine.

SSH Connection | Volumio Developers Documentation
type:
cat /dev/input/event0
press buttons and see if there is a response, if yes note it down and continue to the next
cat /dev/input/event1
press buttons and see if there is a response, if yes note it down and continue to the next
cat /dev/input/eventx
so if in your case event1 and event2 triggers a response update the code:
mousea = InputDevice(‘/dev/input/event1’)
mouseb = InputDevice(‘/dev/input/event2’)
and change
for device in mousea, mouseb, mousec, moused:
to
for device in mousea, mouseb:
This is where my support stops.
Thanks for your patience. I had actually tried the cat commands before but figured I was doing something wrong as what I got back was this:
Surface Dial Button Push then Left Turn then Right Turn…
then your script would be something like this and save it as mouse.py in /home/volumio.

Also, are all the pcieport & nvme error messages normal?
This is because your device only has one event and this part doesn’t seems to accept only one event.
for device in mousea:
asyncio.ensure_future(print_events(device))
or a very dirty fix:
for device in mousea, mousea:
asyncio.ensure_future(print_events(device))
If the community wants to take over, please do, as I am not going to rewrite this. This is not related to Volumio support.
You can also take a look here, but involves a lot of adaption:
Last contribution on this topic:
cd ~
nano devices.py
copy/paste:
import evdev
for device in [evdev.InputDevice(fn) for fn in evdev.list_devices()]:
print(device.fn, device.name, device.phys)
ctrl+x, enter ctrl+o
run and see which device name you dail has. In my example it’s “ZYSD.Ltd HCY RC”:

Replace mouse.py content with code below. Make sure you update DEVICENAME with yours.
It’s up to you to find the proper keys for your device. I helped you by printing the the key like:
You Pressed: KEY_UP
You Pressed: KEY_LEFT
You Pressed: KEY_RIGHT
You Pressed: KEY_DOWN
You Pressed: KEY_ENTER
You Pressed: KEY_HOMEPAGE
You Pressed: KEY_BACK
You Pressed: KEY_COMPOSE
You Pressed: KEY_VOLUMEDOWN
You Pressed: KEY_VOLUMEUP
also added all possible keys, so you only need to copy paste them in the handling of the button press.
This is now pretty universal.
