I have speakers all over my house. I like to minimize my power usage. Sonos has no API. This is a daemon that "listens" to the audio coming out of Sonos (forked into my home server's line-in) and turns on & off my Denon amps as needed. Now when I come home & pull out my phone and pick some Pandora station, the whole house turns on and parties with me. And it means I never have to worry about turning off amps and wasting my solar power. (hmm, waste solar power? maybe this project is pointless.)
