Howto disable Raspberry Pi Status LEDs with RaspberryMatic

Last modified:

Introduction

I’m using a RaspberryPi 3 with RaspberryMatic distribution to control my HomeMatic thermostats. This distribution has a “heartbeat” functionality, which leds the green LED of the Pi light up in constant time intervals.

These LEDs are quite strong and disturb the sleep of my family. Therefore its time to disable these leds.

Disable the leds

Connect via SSH to the RaspberryMatic installation. Edit or create the file /usr/local/etc/rc.local and add this content:

#!/bin/sh
echo none >/sys/class/leds/led0/trigger
echo none >/sys/class/leds/led1/trigger

Now make this script executeable:

chmod +x /usr/local/etc/rc.local

This script is executed on each start and disables the LEDs completely. No need to use some duct tape to mask the LEDs anymore 🙂
