Show HN: Multi-room audio with Snapcast and Raspberry Pi
I use Snapcast and mopidy on a home server with the iris front end. It integrates with home assistant so you can have automations play sounds in all or some rooms.<p>With covid I've been able to pipe my meetings to snapcast from the web browser (listen only) which is great for restroom breaks and snacks in long unengaging meetings.<p>I rigged up a AC sniffer circuit and wifi microcontroller to my dumb doorbell which snapcasts a recording of a doorbell chime throughout the house when it's pressed so I can hear it when music is playing.<p>Snapcast can also stream to a phone, so I can Bluetooth into the hot tub speakers and have it on the whole house audio too.<p>Open source home automation with home assistant and this tech is really fun if you want to get into it as a hobby. Certainly requires work, but that's fun for me.<p>I also have it all integrated into a home-brew weather station and an indoor air quality sensor system with co2 and pm levels so I can get alerts to open windows or turn on fans if co2 gets too high. I also get raindrop noises when it starts raining so I go close the windows. Fun times.<p>Of course there's a security system involved too which arms at night and when the family's WiFi all disconnects. It disarms automatically based on WiFi auth and an openwrt script, so it's totally autonomous. Works very well.<p>Working on a tensorflow based automation now to have the front door camera detect packages and send email alerts. Does not work at all, yet.<p>All local, all self-hosted, with a bridged MQTT server on a VPS for communicating with my location tracker and my mom's house (I get alerts if she's on vacation and the furnace dies or basement floods or there's a break in or whatever). I vpn in to my router to control things when  out. But if internet dies at home, everything local still works great.<p>Mopidy also connects to Spotify, of course.<p><a href="https://mopidy.com/ext/iris/" rel="nofollow">https://mopidy.com/ext/iris/</a><p><a href="https://www.home-assistant.io/" rel="nofollow">https://www.home-assistant.io/</a>
