openHAB - a vendor and technology agnostic open source automation software for your home
Categories:
openHAB is a vendor- and technology-agnostic open source automation software for your smart home.
π Overview
openHAB is an open-source home automation platform that unifies control over smart devices from hundreds of manufacturers, enabling seamless integration, automation, and local control without cloud dependency.
It solves the problem of smart home fragmentation where devices from different vendors use incompatible protocols, by offering a pluggable architecture supporting over 400 technologies and thousands of devices. Users gain privacy through local execution on their hardware, with optional cloud bridges to services like Amazon Alexa, Google Assistant, and Apple HomeKit.
Who is it built for? Home automation enthusiasts, DIY makers, and privacy-conscious users seeking flexibility beyond proprietary ecosystems.
Why did you build it? The openHAB community created it to provide a truly open, extensible platform free from vendor lock-in, empowering users to control their homes fully.
β¨ Key Features
- Pluggable architecture with 400+ integrations and 3000+ devices support (what it does: connects everything; why: eliminates silos)
- Powerful rules engine for automations using triggers, JavaScript/Python scripts, actions, notifications, and voice control (flexible logic)
- Local-first with web UI, iOS/Android apps; easy setup via openHABian for Raspberry Pi or Docker
- Vendor-neutral and privacy-focused, with community-driven add-ons
- Optional: Experimental features like new bindings and UI enhancements in development
π Tech Stack
- Backend: Java, Apache Karaf (OSGi runtime)
- Frontend: Modern web UIs (JavaScript/TypeScript)
- Database: Configurable persistence (e.g., rrd4j, InfluxDB, JDBC)
- Auth: Built-in user management / external integrations
- Hosting: Self-hosted (Docker, Raspberry Pi/openHABian, Linux/Windows/macOS)
