The `airnow` integration uses the [AirNow](https://www.airnow.gov/) 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](https://docs.airnowapi.org/account/request/) 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.
