@tbowmo Thank you very much for your response and explaining.

Hello,
is it possible, that the Sketch posted here, does not work with the MySensors libraray V2.0? There have been removed many libs, (SI7021, sha204, RunningAverage), which are used in the Sketch "SensebenderMicro.ino" V01.4.
I had a little bit trouble last weekend, to get it run.
I switched back to Mysensors lib 1.56 and used the expamle Sketch "SensebenderMicro" which was included in this lib. Then it worked.
But thanks for this Great Projekt, and this great Board Sensenbender Micro
