New Additional Indoor module DOA?

Post by bar2 »

My brandnew additional indoor module shows abnormal high CO2. I did now put it next to standard indoor and it shows 1894 ppm vs. 842 ppm standard.
It does not need some time to calibrate, does it?

Temp shows 0.2 C difference and humidity 2% difference, which is acceptable?

I think I found my answer:

To ensure accuracy of your CO2 measurements, the Netatmo Weather Station automatically and regularly recalibrates its CO2 sensor. This calibration is performed assuming that the CO2 level surrounding the Station lowers to 400 ppm at least once a week. To achieve a precise calibration, make sure to ventilate the room for a period of time long enough to entirely renew the room air.
