Pironman5 & Kali: Configuring Shutdown to Deactivate GPIO Power

Accessories for Raspberry Pi and Arduino
1

Hello,

I’m using Pironman 5 with Kali Linux now (the latest version/update). The only thing I got not configured was the the switchoff of the LEDs, at least the red one at the fromt is on when the system has been powered off.

The point Configuring Shutdown to Deactivate GPIO Power does not work, as there is no rpi-eeprom-configon Kali. Does anyone know, which config file I might need to modify with POWER_OFF_ON_HALT=1?

Config: Pironman5 + Raspi5 4GB + Kali 2025.1c + Updates from 2025-05-01 + Pironman5 Software 1.2.7

Thanks, Mathias

By default, the Kali system is pre-configured to disable GPIO power upon shutdown, so no manual configuration is required.

To verify, please try shutting down the system by pressing the power button and check whether the RGB fans, OLED screen, and onboard RGB lights turn off properly.

After shutdown, a red LED on the Pi5 indicates a normal and safe power-off state—this is expected behavior.

Note: After upgrading the official Kali system, the command sudo rpi-eeprom-config -e is no longer functional.

Hmm, I’m not sure what I did wrong, but now it is - in addition to the red front led - also illuminating the fan leds and spinning fan 2 after the “powering off” message.

We’ve performed thorough testing on our end with the following steps:

  1. Installed Kali Linux system
  2. Installed Pironman5 software
  3. Executed shutdown commands:
  • sudo shutdown -h now
  • sudo poweroff

Results:
All outputs shut down normally, including:
✓ RGB fan power off
✓ IO expansion board output disabled
✓ Onboard RGB lights deactivated

The same successful shutdown behavior occurred when using the physical power button.

Recommendation:
Since we couldn’t replicate the issue you encountered, we suggest:

  1. Installing the official Raspberry Pi OS
  2. Reinstalling Pironman5 software
  3. Performing a safe shutdown to verify if the RGB fan persists

This will help determine if the issue is system-specific. Please let us know your test results - we’re happy to provide further assistance.

Hi,

Test 1: Raspbian latest + Pironman5 install
Fan, RGB and internal lights off, front led glowing red on

  • shutdown -h
  • poweroff
  • Shutdown via graphical menu (no clue what this triggers in the background)

Test 2: Kali latest + Pironman install
Fan, RGB and internal lights off, front led glowing red on

  • shutdown -h
  • poweroff
  • Shutdown via graphical menu

So, I understand this is the expected behaviour now. Would it be nonetheless possible to have the front led off when the system has shut down? Maybe there’s a setting for that.

Cheers, Mathias
