Hi all
I've got a logitech media server (LMS) setup with pi's all over the house that can synchronise playback from spotify and my personal music library. I use tablets & phones to control volume of the different players, as well as a Mycroft instance I can ask music requests and basic playback commands. All good so far...
I'd love to have something physical like a remote control or better a dial/potentiometer on a wall to control volume on each player. Controlling the players with wifi is easy: some simple commands via http on any browser is all it takes:

Can anyone thing of a creative/cheaper solution that avoids having to buy arduino shields & boards to achieve something like a physical knob or remote for volume control?
cheers
John
