Open-source home automation running entirely locally — control 3,500+ smart home integrations with no cloud dependency, no subscription, and no data leaving your home.
Open-source smart home platform — local-first, no cloud required.
Home Assistant is the world's most popular open-source home automation platform, letting you control, automate, and monitor all your smart home devices through a single local interface — without cloud connectivity or subscriptions. With 3,500+ integrations covering everything from lights and thermostats to security cameras and energy monitoring, it runs on a Raspberry Pi or dedicated hardware inside your home.
Automations trigger on time, location, sensor state, or any combination using a visual editor or YAML. A fully customisable dashboard shows exactly what you want — room-by-room energy use, security camera feeds, or weather data. The built-in Assist voice engine processes commands locally without routing speech to external servers.
Key benefits:
- 3,500+ integrations covering virtually every smart home ecosystem and device brand
- 100% local processing — no cloud dependency, no subscription required for core use
- Visual automation editor with triggers, conditions, and multi-step action sequences
- Customisable dashboards with drag-and-drop cards for any device or sensor
- Local voice assistant (Assist) with no speech data sent to external servers
- Matter and Thread support for the latest smart home interoperability standards
- Open-source (Apache 2.0) — self-host on Raspberry Pi, VM, or dedicated hardware
Home Assistant is governed by the Open Home Foundation, a non-profit based in Switzerland, structured to ensure the platform can never be sold or shut down by a corporate acquirer. All data stays on your own hardware by default — no telemetry, no profiling, and no vendor with access to your home. Fully GDPR-compatible by architecture.
Trusted by more than one million households worldwide — ranked the top open-source project by contributors in 2025.
