Hi y’all!
I wanted to be able to monitor air quality in the Netherlands.
Luchtmeetnet provides an API to do this.
Next to individual readings (for instance NO2, PM10) I wanted a general index for air quality ( Luchtkwaliteitsindex). I’ve modeled this the same way Luchtmeetnet does (see here).
To be able to use this piece of code, you need to find a measuring station ID, from a station that measures the particle measurement you want. I use multiple stations because the station near me did not measure O3.
The easiest is to first find the station you want on this map. When you know the names, you can get the station ID with this url:
https://api.luchtmeetnet.nl/open_api/stations?order_by=&organisation_id=&page=1
Change the page number to find more stations.
Make sure the station actually supports the measurement you need.
After this, you can add to your HASS config, and change the station ID numbers:
