Dear HiFiBerry community -
I'm enjoying HiFiBerryOS but it needs one small thing to be perfect: a simple way to control the GPIO pins as an action in interactions. As it is the system is offering serial messaging but this is more sophisticated than I need or can use.
For example, I want to turn on an amplifier controlled from a relay attached to the GPIO header.
node.js is installed but I think the modules onoff and socket.io are not. I don't wish to modify the installation at all, so that I will not have to worry about future updates resetting my changes.
Any ideas or workarounds?
