This repository contains the official set of add-ons that are implemented on top of openHAB Core APIs. Add-ons that got accepted in here will be maintained (e.g. adapted to new core APIs) by the openHAB Add-on maintainers.
To get started with binding development, follow our guidelines and tutorials over at https://www.openhab.org/docs/developer.
If you are interested in openHAB Core development, we invite you to come by on https://github.com/openhab/openhab-core.
Some add-ons are not in this repository, but still part of the official openHAB distribution. An incomplete list of other repositories follows below:
- https://github.com/openhab/org.openhab.binding.zwave
- https://github.com/openhab/org.openhab.binding.zigbee
- https://github.com/openhab/openhab-webui
openHAB add-ons are Java .jar files.
The openHAB build system is based on Maven. The official IDE (Integrated development environment) is Eclipse.
You find the following repository structure:
.
+-- bom Maven buildsystem: Bill of materials
| +-- openhab-addons Lists all extensions for other repos to reference them
| +-- ... Other boms
|
+-- bundles Official openHAB extensions
| +-- org.openhab.binding.airquality
| +-- org.openhab.binding.astro
| +-- ...
|
+-- features Part of the runtime dependency resolver ("Karaf features")
|
+-- itests Integration tests. Those tests require parts of the framework to run.
| +-- org.openhab.binding.astro.tests
| +-- org.openhab.binding.avmfritz.tests
| +-- ...
|
+-- src/etc Auxilary buildsystem files: The license header for automatic checks for example
+-- tools Static code analyser instructions
|
+-- CODEOWNERS This file assigns people to directories so that they are informed if a pull-request
would modify their add-ons.
To build all add-ons from the command-line, type in:
mvn clean install
Optionally you can skip tests (-DskipTests) or skip some static analysis (-DskipChecks).
This does improve the build time but could hide problems in your code.
For binding development you want to run that command without skipping checks and tests.
To check if your code is following the code style run mvn spotless:check.
If Maven prints [INFO] Spotless check skipped then run mvn spotless:check -Dspotless.check.skip=false instead as the check is not mandatory yet.
To reformat you code run mvn spotless:apply.
Subsequent calls can include the -o for offline as in: mvn clean install -DskipChecks -o which will be a bit faster.
For integration tests you might need to run: mvn clean install -DwithResolver -DskipChecks
You find a generated .jar file per bundle in the respective bundle /target directory.
We have assembled some step-by-step guides for different IDEs on our developer documentation website:

Happy coding!
