The concept of Netatmo weather station has convinced me from the beginning. Operation is simple, the design convincing. Unfortunately disappointed the weather station in its basic function. The first copy that I have returned, completely showed wrong values. The replacement copy is now indeed correct values for temperature and humidity, but the pressure was still completely wrong, 6MB too little. The support has indeed now "calibrated" on request. But simply to add more than 6MB to that does not mean too. I do not understand why you can not install a functioning air pressure sensor in a weather station in this price range. Anyone who is interested in correct values, I can only strongly advise against this weather station.
