I am developing a small “button board”, which will be used to control some home appliances. So far, I just wired up some buttons to the GPIO pins of my raspberry and added them via the GPIO-binding. Here is a picture of the prototype:
So far this was really simple, but now my housemate asked for a volume knob. This is not possible via the binding, right? Right now my solution would be to get one of these:
and query them with some sort of script
I was wondering if there is any direct way to read the values to openhab. I am pretty sure somebody tried something like this before, but I haven’t found anything in the forum. Hint me in the right direction. Thanks!
