What is Home Assistant?
Home Assistant is open-source home automation software that puts local control and privacy first. Unlike cloud-dependent smart home platforms, it runs entirely on your own hardware—keeping your data safe at home while connecting thousands of devices from over 1000 brands. Whether you're a DIY enthusiast or just want a smarter, more private home, Home Assistant gives you full ownership without selling your data or locking you into proprietary ecosystems.
Backed by the non-profit Open Home Foundation, Home Assistant is built and maintained by a passionate global community of tinkerers, developers, and everyday users. With powerful automations, customizable dashboards, and its own private voice assistant called Assist, it turns your house into a responsive, efficient, and truly personal smart home—all without relying on the cloud.
