I currently have a Squeezebox setup with Raspberry Pi’s and am able to detect when the power on command is sent to the squeezeplayer. I have a script that listens for this, then sends an IR signal using the GPIO and a IR Blaster to my receiver to turn it on. Is there a way to detect when the “speaker” is receiving audio, thus allowing me to do the same thing with SoundSeeder?
Basically you install the xPL Interface plugin in LMS. This broadcasts events like power on, power off, etc… for the different players. The script listens for these events for the specified player name and sends an IR code using lirc to the stereo to turn it on and off.
