Same on this FC39 box...
With 5.27.10/Frameworks 5.112.0-1  I could choose hardware, Sensor Details > Click to select Sensor > Hardware and all my hardware sensors are listed IE lmsensors/it8655-isa-0290/ 

With the Beta, Sensor Details > Click to select Sensor > Hardware, the only option has some random "Temperature 1" and that's it.

Just giving my "Same here" as well.
I can see only 3 sensors instead of tons that I have (zenpower + nct6795 + nvme)  and, for the ones that I can see, they don't yield any value on plasmoid.

Same thing for me. The zenpower provided sensors are missing, although they are showing in the `sensors` command:

zenpower-pci-00c3

SVI2_SoC:    994.00 mV
