Tally light for OBS source using rpi, rgb leds, and obs-websocket Each pi will sit and look for a websocket connection. Once connected, it will light yellow when the provided source is in preview and green when its in program

1. Install the watchgod and websockets library as root, used to run the script sudo pip3 install websockets

2. Install and Setup NGINX and PHP Server: https://www.raspberrypi.org/documentation/remote-access/web-server/nginx.md

(If using php 7, also install php-xml - sudo apt install php-xml)

3. Put index.php in /var/www/html/

4. In index.php change tally.xml-path to match the actual path (and make sure nginx can write to it)

5. Run index.php from a browser

6. Setup OBS-Tally Settings (IP, Password, Port from OBS-Websockets, Scenes and GPIO-Ports)

7. Connect LEDs to the matching GPIO

   • sudo update-rc.d -f nginx defaults;
   • sudo nano /etc/rc.local
   • just above line 'exit 0' insert:

   (
           cd [/path/to/obs-tally]
           python3 obstally.py &
   )
