It seems LibreElec was having the same problem when they released their version 11.0. From what I can understand the poe-hat(-plus) was not enough to control the fan for this to work the pvm-fan was also required as well as the gpio-fan. It is all explained here: RPi4 POE-Plus hat not working in LE11.0.1 - Bug Reports - LibreELEC Forum
I’ll check this out.
We’ll be moving to a new 6.1 kernel soon for Raspberry Pi.
I’ll keep an eye on this issue, let you know when it’s available for testing and this should finally solve the issue.
I will wait for your instructions a test asap.
Is the fix part of August update?
No. We are still using 5.15.
The same issue here - RPi 4, PoE+ hat, kernel 5.15.92-1-osmc.
You will need to wait for the 6.1 kernel.
We will have a testing thread soon.
