@tag Thank you for the feedback.

the CPU temp is shown as 0.049c instead of 49c

I have filed an issue with pi4j. Seems it's fixed. Let me check with recent version and update.

Which image do you use (in my opinion armbian jesse is still the best..)

Yes, I too use armbian. Which is super cool image for Orange PI

and what is "hot" 🙂 can you keep your finger on the cpu for a minute?

Sure, Will update you 🙂
