How to turn off Raspberry Pi LEDs
-
Hello, I have a question.
I am using the Raspberry Pi 4B and tried turning the power led and other status leds off configuring the boot/config.txt file and using the “echo 0 | sudo tee /sys/class/leds/led{1,0}/brightness” command. However, they didn’t change anything. I think this is due to the pm2 and the boot/config.txt somehow gets skipped when booting.
Does anyone have suggestions how I can turn them off or run the boot/config.txt file?
Thank you very much for your help! -
@GuestMirror never heard of any option to turn off the LEDs except on pi0w.

@GuestMirror boot/config.txt is processed long before pm2 is started…
-
@GuestMirror Try this in bootconfig.txt
# Turn off PWR LED dtparam=pwr_led_trigger=none dtparam=pwr_led_activelow=off # Turn off ACT LED dtparam=act_led_trigger=none dtparam=act_led_activelow=off # Turn off Ethernet ACT LED dtparam=eth_led0=4 # Turn off Ethernet LNK LED dtparam=eth_led1=4 -
@sdetweil Is there a way to see if the boot/config.txt loads properly? I tried troubleshooting it by setting different things in there like rotating the display etc. however, even with all my other changes commented out nothing changes when booting.

@Fozi I already tried that but it won’t work for some reason.

@Fozi @GuestMirror
Works on my RPi 4
I just copied and pasted to the bottom of the config.txt did a PM2 stop all and then sudo reboot and when it came backup they where on for a few seconds and then went off. @GuestMirror are you in the /boot/config.txt?@Fozi said in How to turn off Raspberry Pi LEDs:

Hi,
I do not have a Pi 4 but on my Pi 3 Model B I have this:
sudo nano /boot/config.txt# Disable the PWR LED dtparam=pwr_led_trigger=none dtparam=pwr_led_activelow=off # Disable the Activity LED dtparam=act_led_trigger=none dtparam=act_led_activelow=offcrontab -e@reboot echo 0 | sudo tee /sys/class/leds/led1/brightnessYou can try this to see if the above cron entry works (before rebooting):
echo 0 | sudo tee /sys/class/leds/led1/brightnessPerhaps some stuff does not work or does the same, but both the power LED and activity LED on my Pi are off in the end.
Btw, on my Pi 3 Model B Plus, only the /root/config.txt line are needed.Concerning the LAN LED’s I found following:
# Disable LAN-LEDs on Raspberry Pi 3B+ dtparam=eth_led0=14 dtparam=eth_led1=14# Disable LAN-LEDs on Raspberry Pi 4 dtparam=eth_led0=4 dtparam=eth_led1=4Good luck!
