# AirNow

> AirNow is a built-in integration for Home Assistant. It has 1.4k installs sharing analytics and needs the vendor's cloud.

AirNow is a built-in integration that reads air quality data from the AirNow cloud service for a chosen location. It adds sensors to Home Assistant, including an ozone reading and the reporting station the data comes from. Setup happens in the UI and asks for an API key along with the latitude and longitude of the location to monitor. Because the data comes from the vendor's cloud, an internet connection is needed. A diagnostics file can be downloaded to attach to a bug report.
