Netatmo air quality, what does it mean?


One of the entities for the netatmo indoor sensors is air quality, represented by a number.

Does any one know how this is calculated and what it means?

Haven’t found anything in the docs, yet, so any help is welcome.

You’re probaly talking about the Air Quality Health Index.

The Air Quality Monitor Health index is an integer between 0 and 4, that calculates the Health of your home based on Temperature, Humidity, CO2 and Noise levels.

0 = Healthy
1 = Fine
2 = Fair
3 = Poor
4 = Unhealthy

Where do you see that index appear? That entity does not appear for me.
