Missing Fan LED option (On/Off/Follow) in Settings UX

rysock · February 13, 2025, 1:03am

I posted a different issue in which my RGB fan is always turning to ‘always on mode’. In researching I am noticing a missing setting in the UX:

In the instructions View and Control from Dashboard — SunFounder Pironman 5 documentation

There is a screenshot of the UX that an option for the Fan LED to be set to On, Off or Follow.

My UX does not include this option. I only have the Fan Mode setting.

The debug log seems to show that the setting is being passed on init to Follow:

‘gpio_fan_led’: ‘follow’
see below:

25/02/12 19:58:26.817 [DEBUG] FAN update_config: {'rgb_style': 'rainbow'}

Did this UX option get removed intentionally? Is this a bug?
What do these different modes do? On / Off / Follow?

SunFounder_Moderator · February 13, 2025, 10:09am

We are very sorry, but in the current version we have changed the RGB fan mode to “always on”.
If you want to turn off the RGB fan, you can adjust the fan mode to do so.
The option to set the fan LEDs to ON, OFF or FOLLOW is not available in the current version of pironman5.
The screenshot in the tutorial shows the option to set the fan LEDs to on, off or follow, which is an option that is available in the pironman5 V2 upgrade that we are working on and ready to go live, where the LEDs of the RGB fan and the fan can be controlled independently of each other.
and the log display you mentioned:
25/02/12 19:56:21.404 [DEBUG] Update gpio_fan_led to follow
25/02/12 19:56:21.404 [DEBUG] Update gpio_fan_led_pin to 5
25/02/12 19:56:21.404 [DEBUG] Init GPIO Fan with pin: 6
Don’t worry about it, it’s for us to test the subsequent pironman5 V2 upgrade.

You also reported in another thread that after pironman5 components are installed in Home Assistant, the settings are reset after a reboot or shutdown and restart after changing the settings. We have also found that bug and we are currently working on fixing it, so please be patient.
After we fix it successfully, we will reply you on the corresponding post.

I have just purchased the Pironman 5 Max and have a very similar issue.

The “fan LEDs to ON, OFF or FOLLOW” is missing from the settings menu and the RGB on the fans do not light up at all. However the fans do work as they should just no RGB. And the board LEDs work perfectly.

Also the “Set OLED Sleep Timeout” is missing from the settings menu so that the OLED display stays on permanently.

I am running a Pi5 8GB with Raspberry Pi 64 bit Trixie from 2025/12/04.

1, So is the RGB on the Pironman 5 Max now disabled? If not how do I get the RGB to work?

2, How do I set the timeout on the OLED display so it is not on permanently?

Regards

abernathy · January 11, 2026, 8:12pm

1, that should read RGB on the FANS, the LEDs on the board work correctly

SunFounder_Moderator · January 12, 2026, 6:56am

Please confirm if you have installed the correct pironman5 software?
Guide link: Set Up on Raspberry Pi/Ubuntu/Kali/Homebridge OS — SunFounder Pironman 5 documentation

Installation commands:
cd ~
git clone -b max GitHub - sunfounder/pironman5: Code for Raspberry Pi 5 case (Pironman5) --depth 1
cd ~/pironman5
sudo python3 install.py
Please provide the log information for us to confirm:
cat /var/log/pironman5/main.log

RGB fan LEDs are not lighting up?
If the software installation is confirmed correct, a common cause is that the FLED (GPIO 5) jumper on the IO expansion board may not be properly connected.
If the jumper is not connected, the RGB fan LEDs will be turned off by default.
How to set the OLED display timeout to avoid it staying on permanently?
If the software installation is confirmed correct, the OLED screen has a default timeout/sleep period of 10 seconds. After working for 10 seconds, the OLED screen will automatically turn off and enter sleep mode.
To wake up the OLED screen, gently tap the case.
Please provide the OLED debug log information for us:
cat /var/log/pironman5/pm_auto.oled.log
cat /var/log/pironman5/main.log

Please find attached screen printout and logs as I have tried to install the software again. this time on a new SD card. it appears it is loading the pironman5 not the pironman5_max software

sorry could not upload pdf. Comments in bold

thanks for the quick response

regards

Thank you for providing the complete log information for us to review.

Based on the logs you submitted, the software is unable to detect the IO expansion board, which is causing the modules connected to the IO expansion board to malfunction.

Please contact service@sunfounder.com with your shipping address so we can arrange for a new IO expansion board to be sent to you.

abernathy · February 6, 2026, 10:51am

Update, new expansion board was sent out and received in the UK in 9 days. Thankyou for your prompt help and speedy customer service. It is nice to deal with a company with good customer service when things sometime go wrong.
