Many thanks to Jørgen Austvik for writing an integration with openHAB. It pulls data into openHAB via the AirGradient API.
Information can be found on the openHAB Add-on marketplace.
It supports the current indoor and outdoor models. I-9PSL and O-1PST.
It can read all air quality parameters of the sensors (PM, CO2, TVOC, NOx, Temperature and Humidity) but for configuration you need to use the AirGradient dashboard.
Follow the steps in the read me file of the integration.
If you have any specific questions or problem, please head over to the AirGradient Forum.
