Add hardware toggle to disable Raspberry Pi 5 LEDs

[3ddruck12]

Describe the feature

I would like to request a feature to enable/disable the onboard LEDs of the Raspberry Pi 5 via the Home Assistant UI, ideally under:

Settings → System → Hardware

The following LEDs should be controllable:

Power LED

Activity LED

Ethernet LEDs

On Raspberry Pi OS, this can be achieved using config.txt parameters:

/

# Power & Activity LEDs
dtparam=pwr_led_trigger=none
dtparam=pwr_led_activelow=off
dtparam=act_led_trigger=none
dtparam=act_led_activelow=off

# Ethernet LEDs
dtparam=eth_led0=4
dtparam=eth_led1=4

Requested behavior:

A simple on/off toggle in the Hardware section

Changes applied persistently across reboots

Raspberry Pi 5 specific (does not affect other platforms)

Why this is useful:

Reduces light pollution in dark rooms (bedrooms, dashboards)

No need for manual or unsupported boot config modifications

Improves usability for kiosk and wall-mounted setups

Hardware:

Raspberry Pi 5

Home Assistant OS

Use cases

Bedroom installations
Home Assistant running on a Raspberry Pi 5 in a bedroom or sleeping area, where bright LEDs are disturbing at night.

Wall-mounted dashboards / kiosks
Raspberry Pi 5 used behind wall tablets or dashboards, where visible LEDs reduce aesthetics and usability.

Living rooms & media cabinets
Devices placed near TVs or in media racks where constant LED activity is distracting.

24/7 systems
Systems that run continuously and do not require visual LED status indicators.

Accessibility & light sensitivity
Users who are sensitive to light or prefer a completely dark environment.

Parity with Raspberry Pi OS
Raspberry Pi OS already allows disabling LEDs via config.txt; Home Assistant OS should offer a supported UI-based alternative

Current workarounds

No response

Anything else?

Maybe this is helpful as a workaround to someone, but to access the config.txt, I simply mounted the SD card on my Mac using diskutil list and then diskutil mount /dev/disk6s1 (update depending on your diskutil list output). I was then able to access the config.txt file and disabled the LEDs by adding:

dtparam=pwr_led_trigger=default-on
dtparam=pwr_led_activelow=off
dtparam=act_led_trigger=none
dtparam=act_led_activelow=off
dtparam=eth_led0=4
dtparam=eth_led1=4

Actually, the same would be nice for Rpi4 and RPi3.

Now it is possible via:
ssh root@homeassistant.local "cd /sys/class/leds ; for LED in * ; do echo 0 >$LED/brightness ; done"

But Ethernet LEDs cannot by turned off in this way.
To turn them off, the image has to contain mdio-tools (https://github.com/wkz/mdio-tools/releases)
