HomeStage

Let's say you have a little home automation going on, like enjoying music and happen to own some stage lights, and you want to make it a 🔥 music room.

WELCOME TO HOMESTAGE.

This project is a work-in-progress and you're on your own right now.

This fork

I forked the already very good working repository sk89q/HomeStage and modified it for my use case. I removed everything I didn't need to make the code easier for me to understand.

I have LED strips in my home which are flashed with espurna, which means they can be controlled via MQTT. I did not use a microphone but rather the loopback of the raspberry the audio is playing on. I currently have removed the code for the API, but it looks good so I'll probably readd that later.

I'm also directly relying on the beat detection by aubio because using the tempo too had some weird doubled effects for me. I've added an option to enable and disable the system via MQTT, so I can add a "party button" to my house.

Videos of this in action might follow later.

Setup

You need Python 3.6+ on the raspberry, which is only shipped with Raspbian Buster (and higher). Make sure to update the raspberry.

1. Install dependencies using pip: pip3 install -r requirements.txt
2. Run ./homestage-server.py
3. Modify config.py according to your needs, especially the MQTT server address and the MQTT brightness and RGB topics for the lights. If you are using espurna and a 4CH-LED (RGBW), enable Use White Channel in the light settings for better results

Setup pulseaudio on the raspberry

For the used library soundcard to work, you have to setup pulseaudio, which is not used by default on the raspberry. Here's how:

1. sudo apt-get install pulseaudio pulseaudio-module-zeroconf alsa-utils avahi-daemon
2. sudo modprobe snd-bcm2835
3. sudo reboot

I'm also using snapcast, for which I had to put pulseaudio in system mode. That's the tutorial I used for that: https://rudd-o.com/linux-and-free-software/how-to-make-pulseaudio-run-once-at-boot-for-all-your-users
I had to modify Exec with ExecStart in the systemd-file from that tutorial. Also do sudo useradd -a -g pulse-access user (replace user by either pi, snapclient or _snapclient, I'm unsure) which allows the user to access the system pulseaudio instance.

sudo apt-get install libatlas-base-dev ffmpeg
