From the SensorHub 3.10 version to the 4.11 beta if you put the internal temperature (without external sensor tempe) in a data field on any activity, each second goes up and down 0.1 celcius degrees. I attach videos.
I downgraded the Sensor Hub version to 2.50 and that version works fine.
I have reported the error by mail. I hope they solve it for the new beta or the new final version.
