# Tomorrow.io

> Tomorrow.io is a built-in integration for Home Assistant. It has 3.2k installs sharing analytics and needs the vendor's cloud.

Tomorrow.io is a built-in Home Assistant integration that brings weather data and forecasts from the Tomorrow.io cloud service. It provides a weather entity along with sensors for conditions such as cloud base, cloud ceiling, cloud cover, dew point, and feels-like temperature. Additional sensors cover air quality and health concern readings, including China MEP and US EPA measures, as well as fire index and grass and tree pollen indexes. Setup happens in the UI and asks for an API key, a location, and a name. An option lets the interval between NowCast forecast updates be set in minutes.
