Wow, that is a great troubleshooting guide… excellent.
I wish you could help on my issue regarding my GPIO fans only coming on if I set the dashboard control to ‘always on’; they no longer respond to the temperature-dependant settings. My post from a few days ago has no replies yet. The link is: https://forum.sunfounder.com/t/pironman-5-max-gpio-fans-only-work-when-always-on-mode-0-is-selected-on-dash/4765/2
No worries if not, I am just being a bit cheeky 
. It just sounds like an easy fix somewhere as the GPIO fans were responding perfectly to temperature control up until a month or so back. I suppose it could be my upgrade from Ubuntu 24.04 to 26.04 or the latest Pironman software 1.3.x as 1.2.21 definitely worked.
Many thanks if you do get a chance to look.
Best wishes, Nick (aka guage_boson)
