Post-installation steps:

sudo systemctl enable coolercontrold.service
sudo systemctl start coolercontrold.service

Then run coolercontrol from the Desktop or the command line.

Try doing a clean and then reinstalling python-dataclass-wizard. Then install CoolerControl again. That worked for others who faced the ModuleNotFoundError: No module named 'dataclass_wizard' issue in the past.

Check when installing fails:

The GUI won't start. The rest seems to start fine, and I get no errors in the debug.

And it just hangs there, no Gui shown.

Edit: nevermind! had a mistake in my makepkg.conf for rust flags.

Failing to build for me:

Hi @akiba and @sgtnasty,

There is an often overlooked settings option in both the UI and config file called: Startup Delay

This will add the specified number of seconds of delay to the startup procedure of the daemon(s) itself and should hopefully solve your startup issues.

I haven't run into this problem myself when testing a multitude of devices at the same time, but I have heard this from a few issues raised in GitLab: some devices (no clear culprit) not being completely "ready" to communicate when the service starts right after boot-up. That might be related to the motherboard/usb chip used rather than necessarily the devices themselves, but it's hard to say at this point.

@akiba I can confirm that I have the same issue: * ASUS Aura LED Controller * NZXT Kraken X

Every new startup I have to restart the services for coolercontrol to recognize both.

I noticed that if you have more than one device to control, sometimes an error occurs and coolercontrol not recognize one of devices. In my case, I have Corsair Commander Pro and Corsair Lighting Node Core.

A workaround that I have been testing and seems to have worked is delayed start service on boot.

coolercontrol-liqctld.service
coolercontrold.service

I don't know if it's an isolated case on my system.

Just a heads up, if you were previously holding back pyside6 and shiboken6, make sure you clean reinstall python-dataclass-wizard so that it recompiles against the new versions of these two packages - otherwise you wont pass the CoolerControl check() or package() with a module not found error.

Since python 3.11 I had to do remove and do a clean package build then reinstall python-dataclass-wizard when it fails. Run the install again and it should work this time.
