The major problem seems to be the humidity sensor.At this moment the reading are:
* Netatmo: 19.3C / 60%
* Davis weather station: 20.6 / 44%
* electronic T/humidity sensor: 20.7 / 46%
* mercury thermometer: 20.5C
* hair hygrometer: 44%
The accuracy of the humidity measure is very important to check the indoor comfort!
And humidity can change really fast when opening windows or turning on/of mechanical ventilation. Why the netadmo is so slow to check the humidity changes?
I think that support should give a clear and reliable answer about the accuracy of the temperature, humidity and CO2 sensor.
It seems that the data in the specification table is not what these users found in their devices.
Can you give us the data specification of the sensors inside netadmo please?
