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 — health, public administration, 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.

Frequently asked questions

Is openHAB a good alternative to Google Home?

Yes — openHAB is one of the top-ranked European alternatives to Google Home in our directory, covering the same consumer products use case. It is headquartered in Germany, keeping your data under EU law by default.

What's the main difference between openHAB and Google Home?

The biggest difference is jurisdiction: openHAB is based in Germany and operates under GDPR and EU data-protection law, while Google Home is headquartered in US and may transfer data outside the EU. For regulated industries or organisations following Schrems II guidance, this difference is decisive.

Is openHAB GDPR-compliant?

openHAB is a European company based in Germany, so GDPR compliance is the default operating model — not a bolt-on. No transfer impact assessment is required for EU customers, unlike when using Google Home.

How do I migrate from Google Home to openHAB?

Start by exporting your data from Google Home (most providers offer an export in their settings). Then import into openHAB using its native import tool or migration guide. Running both in parallel for a week catches any feature or workflow gaps before you fully switch.
