The wiki page here contains outdated documentation for the older openHAB 1. Please be aware that a lot of core details changed with openHAB 2 and this wiki as well as all tutorials found for openHAB 1. If you are completely new to openHAB 1. If you speak German, you can find an openHAB 1. It is therefore a pure Java solution and needs a JVM to run. Being based on OSGi, it provides a highly modular architecture, which even allows adding and removing functionality during runtime without stopping the service.
Here is an overview of the main bundles and how they depend on each other:. All bundles that do not require stateful behaviour should use it to inform other bundles about events and to be updated by other bundles on external events.
All protocol bindings which provide the link to the real hardware devices should communicate via the Event Bus. This makes sure that there is a very low coupling between the bundles, which facilitates the dynamic nature of openHAB. This is a light-weight pub-sub implementation, which perfectly meets the requirements. It is important to note that openHAB is not meant to reside on or near actual hardware devices which would then have to remotely communicate with many other distributed openHAB instances.
Instead, openHAB serves as an integration hub between such devices and as a mediator between different protocols that are spoken between these devices. In a typical installation there will therefore be usually just one instance of openHAB running on some central server. Not all functionality can be covered purely by stateless services.

Therefore openHAB also offers the Item Repository, which is connected to the Event Bus and keeps track of the current status of all items. The Item Repository can be used whenever needed to access the current state of items.
Also the automation logic execution engine needs to always be informed about the current states. The Item Repository avoids requiring each bundle to cache states themselves for their internal use.
It also makes sure that the state is in sync for all those bundles and it provides the possibility to persist states to the file system or a database, so that they are even kept throughout a system restart.
openHAB 2.5 Release Notes
The Sitemap is a tree structure of widgets, which define the different pages of a UI and their content. The definition of the Sitemap is quite abstract by design; it is supposed to be a suitable UI model for different kinds of user interfaces, so that the user does not have to configure each of them in case he sets up multiple UIs. If a UI has further requirements on top of the sitemap, it is still possible to introduce additional configuration options which are then specific for the UI in question.
Item UI providers offer a dynamic way to configure the UI, so that not everything must be stored statically in the Sitemap. An item UI provider can for example define, what widget should be used for an item, if none is specified and can dynamically define icons and labels which might depend on the current state of the item for the widgets.
An important use case for this feature is the dynamic display of item groups - all that there is stored in the Sitemap is the information that a certain group should be displayed; the page is then dynamically assembled at runtime with whatever items are available at that time.
It comes with editors for configuration files like the sitemap. Its advantage over simple text editors is the full IDE support, like syntax checking, auto completion, highlighting and content assist. It is also meant to implement and deploy rules for automatic actions. The wiki pages here contain outdated documentation for the older openHAB 1.
Please be aware that a lot of core details changed with openHAB 2. A good source of inspiration and tips from users gathered over the years. Be aware that things may have changed since they were written and some examples might not work correctly. Skip to content. Home Jump to bottom. Attention: openHAB 2. Overview The openHAB 1.Both utilities and vendors of home control have promoted such standards aggressively. It should be distinguished from the openADR standards that were promoted to ensure open access to customer electricity use data by all service providers.
A major rationale for a single set of standards is for the utilities themselves to provide a unified home energy monitor that "provides prompt, convenient feedback on electrical or other energy use. Devices may also display cost of energy used, and estimates of greenhouse gas emissions. Electricity use may be measured with an inductive clamp placed around the electric main, via the electric meter either through an optical port, or by sensing the meters actionsby communicating with a smart meter, or by direct connection to the electrical system.
In the US, the National Broadband Plan emphasized in its "goal 6" that consumers must be able to share usage data with literally any service provider, not just their electric distributor, who must then be able to provide simple instructions or direct remote control of the consumer's residential appliances and home grid.
Utilities accordingly have been motivated to remain ahead of the technology curve and aggressively roll out these capabilities internally. When integrated with the billing process for either print or online presentment, the utility can communicate to the customer valuable information to increase the understanding of energy use, its drivers, how to save, and comparisons to standards in their area.
Unlike most other networking standards, it uses in-home wiring between AC-powered devices. The closest DC equivalent is power over ethernet PoE. These [ which? In the OpenHAN architecture, "The display portion is remote from the measurement, communicating with the sensor using a cable, power line communications, or using radio.
Online displays are also available which allow the user to display near real-time consumption on any device that can connect to the Internet. These displays can reduce household energy consumption by providing real-time feedback to homeowners so they can change their energy using behavior.
Hydro One subsequently offered free power monitors to 30, customers based on the success of the pilot. Blue Line Innovations also indicatesunits in the market today. According to the utilities involved, all smart appliances and smart meters which also must meet openADR standards for energy demand management must meet the OpenHAN standard. Its appliance interface connector  is meant to ensure that all openHAN devices can communicate with each other.
The energy services interface  defines how energy use is managed. Implementing companies include Synapse, the ZigBee and HomePlug consortia, TrilliantUnited IlluminatingIngersoll-Rand and others closely affiliated with the utilities and seeking to sell them more equipment.We will later use MQTT. Let us take a look how we can level this new power to integrate our IP camera into an existing smart home. The configuration files for open hub can be found in the.
Eventually we will populate this file with devices that require a thing declaration, keep in mind that not all devices need it. To be able to access things - such as a light switch - we need to add them to an items file office.
For demo purposes we can add a Switch Item :. In this case Switch will be the type of item we add, MyFirstSwitch is its name and Demo Switch will be used as it's label.
Now we have to add the switch to our user interface, by adding a office. The sitemap file is how you interact with the devices or the user interface:. Type in the name of your sitemap - we used office - and click Save. You can then repeat this step with the Classic UI :. To add functionality to our switch, we need to add a office. This is the file that does all the automation. Search for Cloud to find the Addon and install it:. Go back to to MyOpenHABmake sure that you are logged in, and you will see a Online notification on the top right - if not, stop and restart the OpenHAB service from your console and refresh the webpage.With its pluggable architecture openHAB supports more than different technologies and systems and thousands of devices!

Why openHAB? Integrate Everything With its pluggable architecture openHAB supports more than different technologies and systems and thousands of devices! No Cloud Required More than supported things! Ready to join the community? Let's Meet Up! Next event.While a device or service might be quite specific, Items are unified substitutions inside the openHAB world.
Items can be Strings, Numbers, Switches or one of a few other basic Item types. A programmer can compare Item types with base variable data types of a programming language. An Item does not simply store information that is set by software e. But let's not get ahead of ourselves. The rest of this page contains details regarding Items and is structured as follows:.
Items are basic data types and have a state which can be read from, or written to. Items can be linked to a Binding channel for interaction with the outside world.
For example, an Item bound to a sensor receives updated sensor readings and an Item linked to a light's dimmer channel can set the brightness of the light bulb. Through Paper UI. Generally all 2. Note that 1. Through text. Files here must have the extension.
However, each Item must be unique across all.What is the BEST choice for home automation in 2018!
Refer to the installation docs to determine your specific installation's folder structure. Generally 1.
Assumptions for Paper UI: The examples below assume that the user is using a text editor to create a. While the way of defining an Item using the graphical, interactive Paper UI is different, the elements and the nature of an Item definition are identical using either method. Editor Recommendation: It's recommended to edit. Doing so will provide you with full IDE support including features such as syntax checking, and context assistance.
The Item type defines what kind of state can be stored in that Item and which commands the Item will accept. Item types are comparable to basic variable data types in programming languages. Each Item type has been optimized for a particular kind of component in your smart home. This optimization is reflected in the data and command types. More details about all of the available Item types and their commands are available under Concepts, see: Item Types Overview.
To learn about the technical internals of the individual Item types, please refer to: Javadoc on Generic Item and its subclasses.This binding supports multiple clients connected to a Plex Media Server. With this binding, it's possible to dim your lights when a video starts playing, for example. Here's a short demo video.
Most changes are pushed to the binding using web sockets. If you have Plex Home enabled, you need to fill in your plex.
A Plex server can have multiple clients. This can be found by signing into plex. You may need to start a video in your client first before it shows up in one of those local server URL's. Note: not all Plex clients support all properties. Status properties work on all platforms, except for the power property in the web client. Navigation commands are not support by the Android nor the web client. Cube MAX! System Integrations.

You can check the OpenHAB service status by typing:. The easiest option for installing Java is to use the version packaged with Debian. This package will install OpenJDK version 1. Java 8 is the current Long Term Support version and is still widely supported, though public maintenance ends in January This will allow you to run almost all Java software. Verify that the JDK is installed by checking the version of javacthe Java compiler:. We highly recommend that you read the Concepts Introduction.
It introduces a number of important ideas that will help you as you install and begin to configure openHAB for the first time.
Once you have openHAB up and running, the Configuration Guide contains everything you need to know to get your openHAB installation talking to different devices around your home. For instance, you can use Sitemaps to control how the status of these devices are displayed on different openHAB User Interfaces, and you can begin to experiment with Rules in order to get the most out of your installation.
There are many other ways of interacting with your openHAB smart home: the most popular are presented in the Interfaces and Ecosystem section below. It does not yet cover all aspects, so you still need to resort to textual configuration files.
Add-on management : Easily install or uninstall openHAB add-ons :. Add your brokers IP address and the broker port - by default this is Note that we are first not going to use TLS encryption. We will add it once we are able to establish the connection:.
Then save your setting by clicking on the blue confirmation button:. Click on the blue button to confirm:. Back in the Thing Menu click to edit the Thing you just created:.
Unfortunately OpenHab does not offer a simple button. Click on Save to confirm:. Note the MQTT. Instead of using MQTT. All right that's it - the Binding was successfully added and we are now able to control all of our camera functions with the MQTT interface. Once your account is set up and you are signed in, go to the Account Page. Those can be found on your OpenHAB installation under the following paths make sure that you install the Cloud Connector first for them to be generated :.
Click to configure it:. Now go back to your terminal and reboot your Linux system that is running OpenHab with sudo reboot. And this URL will work from anywhere where you have internet access:. For Developer MotionEye Setup.
