@roele Can you please see if you get any meaningful results from latest release? I've built fat/universal binary, it should work on both arm64 and amd64 architecture.
I do get results without any error but some sensors seem to be missing or faulty on the ARM64 architecture. For example there is no temperatures for CPUs, fan current values are missing or battery counts report 0 values etc.

@roele Fan wise, I don't show SMC keys which are all zero, given that there is quite a lot of always-empty SMC keys. In regards to CPU temperatures, it looks like Apple has made M1 Silicon readings available only through IOKit. I'll see what I can do.
I can test if that helps. my M1 Air results in this:

M1 silicon support will need two-staged fix:
- adding new SMC keys (in progress, I'm almost done)
- adding IOKit CGO part (needs some additional work, not yet started) due to most M1 temperature sensors being available only through HID sensors access.
First part is easy, but the second part will take me a few weeks given the other things at hand.
Actually, I wrote a POC that seems to be working already, although it's a little bit more challenging than expected.
@roele @DrPsychick I've made a new release that should be able to properly fetch HID sensor values on M1, please test when you can: https://github.com/dkorunic/iSMC/releases/tag/v0.5.0
I think we can close this now, agreed?
@dkorunic you were too fast with your releases :) Awesome work! I gladly tested 0.5.3:
Battery data seems to be missing. I played with that a while ago and use IOReg to get that info. Not sure if that is of any help, I'm not a C coder by profession.
