Hi Volker, thank you for the reply. I do know the device spec. Also I am perfectly aware that the Sun radiates heat and in my case Eve Weather is under the car shelter's roof, around 2,2 meters from the ground and the place is well ventilated, shed's sides are open. The sun _cannot_ reach the device. In addition to that the weather here is not sunny at all, rather cloudy and snowy, temperature at the moment is -4,3 C. But the Weather thinks its -2,8. I am a bit puzzled.
