## No longer maintained
As of 2023-02-15 (YYYY-MM-DD), this project is no longer being maintained by me and its up for adoption. If you are interested in maintaining it please let me know. This project comes with an Apache 2 license which would need to be respected.
## Description
This plugin facilitates the automation of [openHAB](https://www.openhab.org) items via Node-RED. It's useful if you want to add automation rules, but not want to use the openHAB built-in rules for that. The plugin provides you with nodes in Node-RED that can (when explicitly called via an input message) get and update the state of Items and Groups defined in openHAB. It also provides an openhab2-in2 node that will immediately output message(s) when the relevant Item or Group state is updated or changed.
This plugin supports openHAB versions up until the current latest stable v3.x RELEASE. If you are still using this module with openHAB 2.x than please consider upgrading it. Support for v2 could break at any time since version 1.4.0 of this plugin as I'm no longer testing it and I will [drop support for it altogether](https://github.com/jeroenhendricksen/node-red-contrib-openhab3/issues/39) soon.
This plugin is a fork from Peter De Mangelaere [node-red-contrib-openhab2 package](https://flows.nodered.org/node/node-red-contrib-openhab2) with additions and changes I find useful.
## Installation
Install this package `node-red-contrib-openhab3` via the `Manage palette` menu of your Node-RED instance.
## Technical
The `openhab2-in2` and `openhab2-out2` nodes use GET, POST and PUT requests sent to the [openhab REST API](https://www.openhab.org/docs/configuration/restdocs.html) via the url `http://openhab:port/rest/items/`
The `openhab2-in2` and `openhab2-events2` nodes receive updates via a Server-Sent Events (SSE) connection that is established once per controller and once per events-node, via the url `http://openhab:port/rest/events`.

## Nodes
See [77-openhab2.html](77-openhab2.html) for info on the provided nodes. This is best viewed from Node-RED, adding a node and viewing its corresponding Help page.
## Testing the plugin (for development purposes)
Prerequisites for running this test environment are docker and docker-compose. It allows you to test this plugin for development purposes.
Docker is used to start a clean Node-RED, OpenHAB v2 and OpenHAB v3 environment, with this plugin installed into Node-RED before the service is started (inside the container).
# Start by running Node-RED and OpenHAB
./run.sh
After a little while, you can visit:
- [Node-RED](http://localhost:1880)
- [OpenHAB v3.2](http://localhost:8081)
- [OpenHAB v3.2 (with authentication)](http://localhost:8082)
- [OpenHAB v3.3](http://localhost:8083)
When in the Node-RED UI, you can import [flow.json](test/nodered/flow.json) via the `Import` option, which contains some example tests for each of the nodes, per OpenHAB version, running simultaneously.
You can verify the server sides event connections to be working as well. They are used by the plugin to receive any updates from OpenHAB:
- [OpenHAB v3.2](http://localhost:8081/rest/events?topics=openhab/items)
- [OpenHAB v3.2 (with authentication)](http://localhost:8082/rest/events?topics=openhab/items)
- [OpenHAB v3.3](http://localhost:8083/rest/events?topics=openhab/items)
When finished, you can reset the test-setup from scratch (this also removes volumes):
./clean.sh
