fan2go is unable to set the fan speed on my system

fancontrol and coolercontrol can do so just fine, enabling the corresponding services one-at-a-time.
But when I do sudo systemctl start fan2go, I get the log below from journalctl -u fan2go -f, repeating of course unless I stop the service.
I can also set values manually (as root) in /sys/class/hwmon/hwmon3/ by echoing to the pwm# files and the values stay how I set them. The fans respond accordingly.
Somehow just fan2go seems to be unable to set fan speed values.

@recallmenot Hey there, sorry for the late response.

There have been lots of changes for 0.9.0, can you please retest on the latest version?

Also:

 PWM settings of fan 'front_high': Min 0, Start 0, Max 0

That doesn't sound like a valid configuration, did the initialization fail?
Did you try overriding these values via the config?

I've got something similar happening:

Should fan2go not set the minPWM back to the 95 I have in the config? (this is with fan2go-git built 20 Oct).
