# Antistorm

> Antistorm is a Marketplace integration for Home Assistant. It has 65 installs sharing analytics, needs the vendor's cloud and was last updated April 5, 2025.

Antistorm is an integration that brings storm and precipitation warnings from the Antistorm service into Home Assistant. It adds binary sensors for a storm alarm, a precipitation alarm and whether a storm is currently active. It also provides sensors for storm probability, time to storm, precipitation probability and time to precipitation. Data comes from the vendor's cloud, so an internet connection is needed. Setup is done in the user interface by entering a city name.
