Script to turn on/off light for videoconferencing automatically. Requires a Mac, Oversight, and Shortcuts app.

lights-camera-action.sh

#!/bin/bash

# To use this script:
# 1. Save it on your Mac hard drive somewhere convenient.
# 2. `chmod` its permissions to make it executable. E.g. `chmod 755 handle-camera.sh`.
# 3. In the Shortcuts app, create "Start Conference" and "End Conference" shortcuts that activate lights
#    and do whatever else you want to happen when conferences start and end.
# 4. Download and install Oversight to watch for camera activation/deactivation: 
#    https://objective-see.com/products/oversight.html
# 5. Configure Oversight's "action" panel to run this script. Turn on the option that passes arguments.

# I realize this is hacky. Smart parameter parsing is left as an exercise for the reader. :)
device=$2
event=$4

case $device in (*"camera"*)
  case $event in (*"on"*)
    shortcuts run 'Start Conference'
  ;;esac
  case $event in (*"off"*)
    shortcuts run 'End Conference'
  ;;esac  
;;esac
