Hello !

Netatmo stations do not measure outdoor air quality data. So Weather Station can't collect it.

Hi, yes they do. My Netatmo Desktop dashboard is currently showing the outdoor air quality is 48. This is an outdoor air quality index (AQI). From the Netatmo website...

The AQI can be calculated for the five main pollutants regulated by the Clean Air Act: ground-level ozone (O3), particulate pollution (also known as particulate matter, PM2.5 and PM10), carbon monoxide (CO), sulphur dioxide (SO2) and nitrogen dioxide (NO2).

The Air Quality Index is made up of a value from 0 to 500 and a level of health concern ranging from good to hazardous.

Okay, it looks they might be displaying this data from an external website, rather than the device, is this correct?

I confirm the AQ data you see is coming from an external service which is not very qualitative (except for large cities where the density of stations is high).

To be completely honest, measuring gases/VOC/particle pollution is a much harder job (and therefore the products are more "technical" and expensive) than measuring CO2, noise or temperature. Netatmo could not, in a probe at this price, integrate the measurements of particles, VOC, etc...

For probes like that, you have to buy semi-pro products, like that.

Many thanks for your response. I think when I read it again I guessed that was what was happening. May thanks for your help - the software's great and has been working faultlessly for many months now. Thanks for all your hard work.
