About
World Air Quality Index (WAQI) is a built-in integration that reads air quality data from the WAQI cloud service. It adds sensors for carbon monoxide, nitrogen dioxide, ozone, sulphur dioxide, PM10 and PM2.5, plus the dominant pollutant and visibility measured by nephelometry. Setup happens in the UI and asks for an API key for the service. Because it relies on the vendor's cloud, readings depend on that connection. A diagnostics file can be downloaded for bug reports, and the integration can show notices under Repairs in Settings.
