description OpenHAB Overview

OpenHAB is a free and open-source smart home automation platform offering unparalleled customization and flexibility. It supports a wide range of devices and protocols, including Zigbee and Z-Wave. While it requires significant technical expertise to set up and maintain, it provides a powerful platform for creating complex automations and integrating diverse devices. It's a great option for those who want complete control over their smart home and are comfortable with a command-line interface.

help OpenHAB FAQ

What operating system does openHAB use?

openHAB is open-source home-automation software that runs on platforms such as Linux, Windows, and macOS through Java. Current openHAB installation guidance recommends a 64-bit Java 21 environment, including Eclipse Temurin builds. [openHAB installation guide](https://www.openhab.org/docs/installation/)

Can openHAB control Zigbee and Z-Wave devices?

Yes, openHAB provides bindings for both Zigbee and Z-Wave, but each radio network requires a compatible coordinator or controller. Device support depends on the binding and hardware, so users should check the supported-device list before buying a USB stick.

How is openHAB different from Home Assistant?

Both are open-source platforms that can run locally, but openHAB is built around Java, bindings, Things, Items, and rules, while Home Assistant uses a different integration and automation model. The better fit depends on whether the user prefers openHAB's structured configuration or Home Assistant's broader consumer-focused ecosystem.

Can openHAB keep working if the internet goes down?

Local devices and local rules can continue operating when the openHAB server and device network remain available. Cloud-dependent integrations, remote access, and services that require an external account may stop working until the internet connection returns.
