So there is a Polish company named Airly.eu that monitors air quality / air pollution in multiple locations in Poland and some parts of Europe (map link). They use mostly own air stations but also gather data from public / 3-party sensors. You might be lucky if you are located in a larger city in Germany, Netherlands, Belgium or Great Britain.
They share all data they garther over a Restfull API for free with reasonable limits (1000 requests per day = max. one request every 1.5 minutes).
I've created a simple Node-RED flow that finds the nearest sensor station relative to your GPS location and puts key measurements into MQTT broker:
You may freely download this flow from here:

Note: Before importing flow code, please add node-red-contrib-credentials module to your Node-RED pallete first.
After you publish air measurements to a MQTT broker, you may ask your LoxBerry MQTT-Gateway plugin send it to Loxone Miniserver:
Then it's pretty easy to set up some visualization for outside air quality data:
And this is how it looks in Loxone app:
Other possible uses of outside air quality data:
Have fun!

Other possible uses of outside air quality data:
- TTS with current quality level on leaving home pulse
- bad air warning before taking up any sport activities (for example riding a bicycle)
- push notification to do some actions on heavy air pollution (close windows, etc)
- automatic action on heavy air pollution (stop ventilation, close down external blinds, etc)
Have fun!
