The airnow integration uses the AirNow web service as a source for air quality data for your location.

Setup

To generate an AirNow API key, go to the AirNow Developer Tools Page page.

{% include integrations/config_flow.md %}

The AirNow API allows 500 data updates per hour, but since observations are only updated hourly, the default update rate is set to 2 per hour and should not trigger rate limiting. If you use this API key for other purposes, ensure the total request rate does not exceed 500 per hour.
