Pironman 5 not working correctly on UmbrelOS – OLED display, power button, and missing pironman5.service

Hello, I am having two different problems while trying to use the Pironman 5 MAXcase with a Raspberry Pi running UmbrelOS 1.7.3.

The first issue is related to the power button and OLED display. I saw that older versions of the Pironman 5 used the vibration sensor, but in newer versions this seems to have been replaced and the power button is now supposed to control the OLED display and some of the power functions. In the tutorial video, it says to remove a small jumper/bridge from the board, which I already did, but it did not solve the problem. The Raspberry Pi still behaves strangely and continues to reboot/restart, and the OLED display still does not work at all. Because I am using UmbrelOS instead of Raspberry Pi OS, I also cannot use commands like raspi-config, so I am not sure how I am supposed to change the GPIO or EEPROM settings that are mentioned in the tutorial.

The second issue is that I cannot get the Pironman software itself working correctly. I followed the installation tutorial exactly and the installation process finishes without any visible errors. At the end, it asks me if I want to reboot the Raspberry Pi to finish the installation, and after rebooting I can see that a Pironman folder was created successfully. However, none of the hardware features actually work. The LEDs stay off, the fans do not spin, the OLED display stays black, and I also cannot open the dashboard/interface. When I try to check the service status, the system tells me that pironman5.service does not exist. So it looks like the installation partially completed, but the actual service was never created or started.

I would really appreciate any help or suggestions, especially from someone who has used Pironman 5 with UmbrelOS before.

The issue you are experiencing is that Umbrel OS no longer allows software to be installed directly on the host system. Any installation will disappear after a reboot, which is why you keep seeing the service missing.

We have already completed an Umbrel OS app for the Pironman 5 Max. We are currently finalizing the documentation and will release it soon.

If you need it now, here is a quick way to install it:

In the Umbrel App Store, click the “Add Custom App Store” button in the top‑right corner.

Enter our custom repository URL:

Once added, you will see our two apps in the SunFounder store.

Select Pironman 5 Max and install it.

Wait for the installation to complete.

After that, everything should work normally. Please let me know if you run into any issues.
