The AQI option lets the hexagons disappear.

Please, tell me under which license the repository is distributed?

Hi,

I get all the time only the map - without any data (or sensors).
What is wrong? I have ried different browsers (FireFox, Chrome)

Thanks,
Michael

The wind layer is leaking a huge amount of RAM. If you leave the website running in a tab and forget about it, the browser eventually eats several GB worth of memory.

I suggest to disable the wind layer automatically when the tab is inactive, and/or to not start the wind layer on page visit.

To detect tab activity, maybe look into the document.hidden property.

The problem: sometimes the sensor on the map are green but the air looks healthy but the level of pollution is (relatively) high.

This is even more problematic as the WHO has recently updated their "safe limits" for PM10 and PM2.5 as explained here.
The transition from the color green to yellow on the sensor maps should reflect these new recommendations especially for PM2.5 which is much lower now

Edit:
It's important because "the harm increases fastest at the low levels of pollution." A jump from 5 to 20 micrograms has a worst effect than a jump from 100 to 115 micrograms. (source)

Next PM seems not to be detected as a PM sensor in the current code.
It seems however to be here:
https://github.com/opendata-stuttgart/feinstaub-map-v2/blob/master/src/js/feinstaub-api.js

Es gibt einen Fehler im Code der Karte für das Laden der Daten bei Noise nach 5 Minuten:

Im aktuellem Code : nur "dust":

Normalerweise:

There is a number of mathematical formulas for PM correction when it is high humidity.
Will it make sense to add client side math formulas for correcting the humidity affect?

Today, 2019-12-11, the map is very very slow, often fails to connect.
The Data-upload by the sensor has about 3500ms.
Registration for new user at https://devices.sensor.community/login worked, I got the email.
But I cannot login, theres timeout after pressing login-button.

Is it possible to display the translation of the map not only on recognition of the browser/system language, but also based on a map language selection - drop-down menu or other. Many users have language browser settings other than their primary language.

It is not possible to translate value "Official AQI index" as there are no translation string in the code.
