The weather station comes in the usual good quality of the manufacturer, also the outdoor sensor makes a very solid impression. The setup with an external sensor works fine, but you want - as in my case - in addition connect another 2 sensors, this degenerates due to the scant instructions from in a long trial and error. I admit the weather station 3 stars because you can still find slight variations in my 3 sensors. For example, a sensor measures in comparison to the other in the range of 3-5 degrees C, higher temperatures at the same location. This I feel as though a little annoying because you can not say for sure what the temperature is actually correct. The statistical data of air pressure "Pressure History" refresh itself every second which would not be necessary in my opinion in this frequency, since so constantly is moving on the display. At least you can see so but from afar, that the thing still works ;-)
