About openHAB
openHAB is an open-source home automation platform that unifies smart devices from hundreds of ecosystems, featuring 400+ supported technologies and 3,000+ device bindings plus a powerful rules engine for time- and event-driven automation. It runs entirely on local hardware, keeping private home data out of third-party clouds while still offering optional bridges to major voice assistants.
The platform is built on Java and Apache Karaf (OSGi), deploying cleanly on Linux, macOS, Windows, Raspberry Pi, Docker, and Synology NAS devices. A vendor-neutral architecture lets users mix Zigbee, Z-Wave, KNX, Matter, MQTT, and proprietary APIs under one interface, with optional integrations into Google Assistant, Alexa, and Apple HomeKit when cloud access is wanted.
Key benefits:
- 400+ protocol bindings covering Zigbee, Z-Wave, KNX, Matter, MQTT
- Local-first execution with no mandatory cloud dependency
- Rules engine for automations, scripts, and voice control
- Cross-platform deployment on Pi, Docker, NAS, and desktop OSes
- Vendor-neutral foundation preventing lock-in to any one brand
- Active community with 22,000+ members and 240,000+ forum posts
openHAB is stewarded by the openHAB Foundation e.V., a registered non-profit headquartered in Ober-Ramstadt, Germany, with the project originating in 2010. As 100% open source under EU governance, it is a privacy-preserving alternative to cloud-locked smart-home hubs from Google, Amazon, and Apple.
Why choose openHAB over Google Home?
The decisive argument is data jurisdiction. Google Home is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
openHAB removes that overhead. As a Germany-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
