Turris Omnia LED control script

This shell script is meant to control the multicolor LEDs on a Turris Omnia router running OpenWrt. It allows you to set the LEDs to different color schemes, including a rainbow pattern, pink, white, and random colors.

Features

• Rainbow Mode: Sets the LEDs to a fixed rainbow pattern.
• Pink Mode: Sets all LEDs to pink (255, 20, 147).
• White Mode: Sets all LEDs to white (255, 255, 255).
• Random Mode: Sets the LEDs to random RGB values.

Requirements

• A Turris Omnia router running OpenWrt;
• LEDs exposed via /sys/class/leds/;
• ash shell.

Installation

1. Place omnia-leds.sh in the /root/ directory of your Turris Omnia router by using scp -O or pasting it with vi.
2. Ensure the script is executable with chmod +x omnia-leds.sh.

Usage

• Set LEDs to a rainbow pattern: ./omnia-leds.sh --rainbow
• Set LEDs to pink: ./omnia-leds.sh --pink
• Set LEDs to white: ./omnia-leds.sh --white
• Set LEDs to random colors: ./omnia-leds.sh --random

Running at boot

The easiest way to run the script at boot is by adding it to /etc/rc.local.

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.

sh /root/omnia-leds.sh --rainbow

exit 0

Running with cron

The --random option is ideal for cronjobs. You can add the script to your crontab with crontab -e.

Then add the following line:

* * * * * sh /root/omnia-leds.sh --random

This will randomize the LED colors every minute.
