allsky_fans error

[drakula1981]

Describe the bug
On a brand new install for my allsky camera on my PI5 with the last OS available, I want to control fans in PWM mode with the module allsky_fans.
But I struggle with the following error :
"Module allsky_fans.py failed on line 212 - Need to add 'dtoverlay=pwm-2chan' to /boot/config.txt and reboot"
Of course, I added the following line dtoverlay=pwm-2chan,pin=18,func=4,pin2=19,func2=4 at the end of the /boot/firmware/config.txt file and rebooted and it's still doesn't works.
Any Idea about what i've could missed or did wrong?

• Allsky Version: v2024.12.06_06

Hi everyone!
Just a quick reminder here to find out what I did wrong?
I've been looking at the problem from every angle, but I can't get the PWM mode to work.

It's probably best to wait for the next release which has a lot of fixes for PWM fan control. Its very different between the Pi4 and 5 so I have made a lot of changes to support both.
