I was very excited to find the "Interactions" in HiFiBerryOS. I'd like to notify my home automation system when the music source changes (starts/stops). Unfortunately, it doesn't seem like the "Actions" don't support scripts or webhooks. Is there any way to hack in the support to call a shell script? I suppose I could build an Arduino that received the message via the serial port and relayed it to the home automation server, but that seems incredibly over-engineered.
Trigger a shell script or webhook action from HiFiBerryOS?
