VegaM does not seem to have fan control/readings

[jeanblanchard]

I have a Hades Canyon NUC (Kaby Lake CPU with VegaM integrated GPU)

It does not seem to have any fanX_input or pwmX endpoint, so the app does not start.

PS: after commenting out the fan stuff, the UI started and showed data, but was unresponsive to user inputs. Not sure if i broke something, or if it really doesn't like VegaM...

Please check if the empty sensor branch currently fixes your issue.

Yep, that seems to solve the issue with the missing fan, thanks.

About the unresponsive UI bit, it appears it's not actually unresponsive, just incredibly slow: about 5 to 10 seconds to react to mouse events... Although I should probably have opened another ticket for this issue...

Please do open a new issue for that
