Simple Toggles to Disable LEDs on RPi under System Hardware Menu

[smurfhk]

While’s there’s lots of advice out there for installing SSH (which I have done, with a Key) and amending either the config files under sys/class/leds, or accessing mnt/boot/config.txt (either directly or on an SD Card in WIndows), unless there is a security concern about folks wanting to simply turn off the PWR and ACT LEDs (i.e. the Power or Activity on the Ethernet Port), surely it must be possible to put a toggle under the System/Hardware setting to enable and disable these?

While I am able to dig around in the file system, I am sure many do not wish to do this, so for someone who just wants them off or on, please, please, please consider this as a function or Addon. Thank you.

e.g. on a RPi 3 or 4

Disable Raspi LEDs with HA OS

Thank you! The 4B version worked just fine for me. I only had to find config.txt, which was under /mnt/boot/ , and to get there one needs to type “login” at the HA console. After editing with vi, reboot now does it. Now all there is left to do is figure out how to do the same for the SSD adapter, which has a bright blue LED blinking furiously under the pi, another red one on the bottom, and another, dimmer blue one on the SSD itself. I guess tack glue will have to do.

e.g. on a Rock4 C+

Disable LEDs on Rock Pi

Hello, I am running HA on a ROCK 4C+ via Releases · citruz/haos-rockpi · GitHub I would like to disable the power and activity LEDs. It turns out that for this I would need to configure echo 0 > /sys/class/leds/green:power/brightness echo 0 > /sys/class/leds/blue:status/brightness Sadly, sys is read-only. Can you please help me to disable these two LEDs? Kind regards

Home Assistant deliberately removed gpio control ages ago.

Oh; was there a specific reason for that?

Raspberry Pi GPIO's deprecated? start here and enjoy the rabbit holes

Although when I look at it, this LEDs may not be controlled by GPIOs.

Exactly

@nickrout

Thanks for that. Yes, it appears to just be controlled by a couple of simple software switches in the config.txt file located in /mnt/boot/.

That’s why I say that surely implementing that in HA as a toggle on or off is totally doable (although I don’t personally have that very special set of skills…).

Raspberry Pi 3B

# Turn off Power LED
dtparam=pwr_led_trigger=default-on
dtparam=pwr_led_activelow=off
# Turn off Activity LED
dtparam=act_led_trigger=none
dtparam=act_led_activelow=off
# Turn off Ethernet ACT LED
dtparam=eth_led0=14
# Turn off Ethernet LNK LED
dtparam=eth_led1=14

Raspberry Pi 4B

# Turn off Power LED
dtparam=pwr_led_trigger=default-on
dtparam=pwr_led_activelow=off
# Turn off Activity 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

OTOH I understand black nail varnish works well.

OK… got me there…but it’s less reversible…
