Hi Volker

Actually the Thread-enabled Eve Weather is off (warmer) 1-1,5 degrees when temperatures are around zero or below. I have two of them and soft-reset does not help either. My other outside thermometers are of different type and they report consistently lower temperatures. I have in vicinity local university Physics department and they have set up scientific local weather station and that reports lower temperatures too. Having programmed some thermometer chips myself I can speculate that the sensitivity of the chip used in Weather is not linear and it is possible to compensate the chip readings in extremes by adding or subtracting to the hex/binary value of the output.
