After installing my RPI-5 in the Pironman 5 Mini case and installing the appropriate pironman5 software, the fan and the LEDs all worked and I was able to set the fan LEDs to always on, even when the fan was off. After reloading the Pi software and the pironman5 software again, the fan and LEDs still work, but I cannot set the fan LEDs to on anymore. It accepts the command “pironman5 -fl on” and the configs (pironman -c) show it as “on” rather than “follow”, but the LEDs only come on with the fan. Restarting the pironman5 service, restarting the Pi, and reloading the pironman5 software don’t change that behavior. Any thoughts?

Hi,  
Thanks for getting back to me. I ran into some troubles with the  
installer, in particular, with libjpeg-dev, which has apparently been  
removed from Trixie. Since the mini case doesn’t have an oled, I went  
into the install script and commented out:

#if has “oled”; then

# APT\_DEPS="$APT\_DEPS libjpeg-dev libfreetype6-dev libopenjp2-7 kmod

i2c-tools"  
#fi

which let the installer finish running.

Even after getting the new pironman5 software installed, the behavior is  
still the same (I.E. setting the gpio\_fan\_led to “on” doesn’t work. The  
fan LED only comes on when the fan comes on, like it’s stuck in “follow”  
mode).

I completely removed the pironman5 software and reloaded the new  
version, and then I used the “pironman5 update” command, but none of  
that changed the behavior, even after restarting the pironman5.service.

Anyway, it’s not a big deal and the case is still great. Just thought  
I’d let you know.

Thanks,  
-Doug
