A very good weather station

[About the weather station Netatmo]
Upon opening the box, the conclusion is: the product is finished and bine the station as its external sensor have class.
After just 5 minutes configuration, raw data appears on my iPhone screen. After posting what correspond all areas of the application (using is really well done), its overall operation is well understood. No worries about that.
Compared to temperature measurements, I have a difference of 0.4 ° C between the station and a thermometer placed next. Same for the outdoor sensor, a difference of 0.5 ° C maximum. For me, it is widely acceptable. Knowing that two identical thermometers placed next to each other does not necessarily appear exactly the same temperature (If so, I tested ^^).
For the rest, difficult to verify the reliability of values, but it gives me an indication of the air quality (and I see the factors that affect the quality) and ambient noise (my daughter is 2 years noisy ^^).
I did not give it 5 stars simply because for me, it lacks a small screen on the main station that would display the current temperature.

[Verdict]
Although more expensive than a non-connected weather station, the station Netatmo is for Geeks like me when people eager to know the air quality in their homes (and whether the house is well ventilated) without having to certainty about the reliability of that information.
I still recommend highly!
