The open Home Automation Bus (openHAB) project aims at providing a universal integration platform for all things around home automation. It is a pure Java solution, fully based on OSGi.

It is designed to be absolutely vendor-neutral as well as hardware/protocol-agnostic. openHAB brings together different bus systems, hardware devices and interface protocols by dedicated bindings. These bindings send and receive commands and status updates on the openHAB event bus. This concept allows designing user interfaces with a unique look&feel, but with the possibility to operate devices based on a big number of different technologies. Besides the user interfaces, it also brings the power of automation logics across different system boundaries.

openHAB 2 is the successor of openHAB 1. It is an open-source solution based on the Eclipse SmartHome framework. It is fully written in Java and uses Apache Karaf together with Eclipse Equinox as an OSGi runtime and bundles this with Jetty as an HTTP server.

openHAB is a highly modular software, which means that the base installation (the "runtime") can be extended through "add-ons". The openHAB distribution includes add-ons from different sources and makes them all available.

Note that the openHAB distribution repository does not contain any source code, but it rather aggregates features from different repos:

• Eclipse SmartHome Framework: This repo holds the major parts of the core functionality.
• openHAB 2 Core: This repo contains a few small bundles that are not part of Eclipse SmartHome, but required for the openHAB runtime. This e.g. contains a compatibility layer for supporting openHAB 1 add-ons.
• openHAB 2 Add-ons: Add-ons of openHAB that use the Eclipse SmartHome APIs can be found within this repository. They cannot be used with an openHAB 1.x runtime, since they provide features that the old runtime does not support.
• openHAB 1 Add-ons: Add-ons developed for openHAB 1.x. Most of them are working smoothly on the openHAB 2 runtime and thus they are packaged within the distribution.
• Eclipse SmartHome Extensions: Since openHAB uses the Eclipse SmartHome framework, it is automatically compatible with all extensions that are available for it and maintained within the Eclipse SmartHome repository. These are usually high-quality extensions that might be even used in commercial products.

The distribution is available in two flavors:

• offline: This package contains all available add-ons and allows installing them locally, i.e. completely offline.
• online: This package only contains the core runtime and downloads any add-on from a remote repository.

For the latest snapshot builds, please see to our cloudbees job.

If you have downloaded the openHAB distribution zip file, simply unzip it to a local folder and call 'start.sh' (resp. 'start.bat') from the command line. The distribution is preconfigured to install demo files, so that you directly have a working instance that you can start playing with.

Once the runtime is started, you can access it in your browser at 'https://localhost:8080/' (note that it might take a bit for the HTTP server to be started, even if the console already welcomes you):

From here, you can directly access all web-based user interfaces like the new Paper UI for administration, as well as the interactive REST API documentation.

For more details on how to get up to speed, please continue reading the Getting Started page.

As any good open source project, openHAB welcomes community participation in the project. Read more in the how to contribute guide.

If you are a developer and want to jump right into the sources and execute openHAB from within Eclipse, please have a look at the IDE setup procedures.

You can also learn how openHAB 2 bindings are developed.
