Save to /data and set permissions.

cd /data
# save file with your favorite editor (nano or vi)
sudo vi lights.sh
sudo chmod a+x lights.sh
  • Note you have to set the ips of your APs. Best if they have fixed addresses.
  • Requires you install sshpass on Firewalla.
  • Credentials are stored in an external file (private=/home/pi/.firewalla/config/post_main.d/pass.txt) Put your ssh password for your APs on a line by itself.
  • Set "user" to the name of your AP username.
  • To make this reusable, I pass two inputs: The last 3 digits of the AP IP and "0" (off) or "1" (on).
  • set baseIP so that it has the common IP for both APs up to the last 3 dgits.
  • fire this off using cron (~/.firewalla/config/user_crontab). Note after you edit user_crontab you have to restart Firewalla for it to take effect. see https://crontab-generator.org/ for help with the cron syntax. Making a mistake can cause issues with Firewalla.

I moved the Unifi username to a local file (defaults to same directory you run the script from lights.txt

user=unifi username here

Important note: tell your controller you want the LED lights on. I saw that if they were off on the controller I could turn them on, but they might turn off unexpectedly. Telling the Controller leave them on seems to allow this method of controlling them on a schedule.
