I’ve been setting up a dedicated display controller for my main Roon system. My wife’s main complaint it’s too hard for her to adjust the volume when she comes in the room while music is playing. So I put together a 12" touchscreen with a Pi4 running the Web extension. But what she really wanted was a volume knob.
So I found one of the nicer USB keyboard based volume knobs on Amazon, and hacked together some code to make it work with the Web Controller. When you turn the knob the Web apps volume slider pops up and tracks your volume changes until you stop moving the knob for a second.
I’d go ahead a publish this a new extension this weekend, but I work for a big internet software company and I have to go through legal to get approval for submitting code to the public domain. It’s largely a formality, but it will take me a couple of weeks to go through the process.
So I’d like to see how much interest there is for something like this before going to that trouble.
