Hi,

It fluctuate quite a lot if I compare to mine. Where is the station located? is it close to a heat source?
Since the post have you seen any changes to the readings after a few automatic calibrations?

I returned it and got a new one, so now problem is solved
Here is from the new.

[Netatmo = deviation]

I have 5 Netatmo modules and they all are crap.
Deviations are all over the place.
I have $8 Chinese equipment with less deviations!
Support is less than poor.... (You'll only get crappy answers after many days or weeks)

Many people are complaining all over the Internet about the Netatmo deviations and the bad support.
So, buying Netatmo is waisted money.


See one of my examples below: 2 CO2 readings. After many calibration attempts outside I placed them to the inside next to each other. Within minutes one of them went bazurk with readings above 2000ppm....
