Hi,
i'm currently doing heat measurements on 2 apq8096 Voxls with voxl-portal im getting different measurements on both voxls:
Voxl 1:

Voxl 2:

both are running the exact same Processes. Could this be code fault of voxl-portal or something different?

Voxl-portal is just publishing data from the ```voxl-cpu-monitor``` service. If you open a terminal window and run ```voxl-inspect-cpu``` you can see the same data. It looks here like the first voxl is mostly idle (2 cores around 20% and 2 around 5%) and the other is pretty heavily loaded (2 around 20%, 1 at 50% and 1 that has been shutdown probably due to overheating). Even if you're running the same processes, they can be utilizing wildly different amounts of the cpu. ```voxl-qvio-server``` is a chief one to keep an eye on, it is known to start churning pretty hard if it's getting bad camera frames (like if the drone is sitting on a desk and the tracking camera sees nothing).
