### NowCast AQI

Comparing µg/m³ values across PM1, PM2.5, PM4, and PM10 gets fiddly. The <a href="https://esphome.io/components/sensor/aqi/" target="_blank" rel="noreferrer nofollow noopener">AQI</a> component folds your PM2.5 and PM10 into a single 0-500 number that maps to the categories in the table above: bigger is worse.

4. Enter `NowCast AQI` for the **Name**, then click **Add** and flash the device.
