I was looking for a handheld remote to control Roon more compfortable like with a smartphone. Now I found a quite interesting DIY project: https://www.yio-remote.com/.
It is a beautiful device intended for smart home and media player control. I decided to participate to the project and implement a Roon control extension.
I wanted to find out if there is some more interest on this solution to decide if I implement a solution just for me or a solution suited for a broader user community.
