# openHAB 2 on Windows

The following instructions will guide you through the process of setting up openHAB 2.

This page is structured as follows:

{::options toc_levels="2..4"/}

* TOC
{:toc}

## Prerequisites

First, be sure to check that your system has the necessary [prerequisites]({{base}}/installation/index.html#prerequisites).

Add the `JAVA_HOME` System Environment Variable in Windows.
Navigate to:

* Control Panel ➡️ System and Security ➡️ System ➡️ Advanced System Settings ➡️ Environment Variables ➡️ System Variables

Create a New System Variable based on your Java installation directory:

![JAVA_HOME](images/JAVA_HOME.png)

The directory that openHAB is installed to must **contain no spaces**.
On this page, we will be using `C:\openHAB2` as an example.

## Installation

The openHAB runtime is distributed using a platform-independent zip file.
To install it, follow these simple steps:

1.  Choose between the Stable Version [![Download](https://api.bintray.com/packages/openhab/mvn/openhab-distro/images/download.svg)](https://bintray.com/openhab/mvn/download_file?file_path=org%2Fopenhab%2Fdistro%2Fopenhab%2F2.0.0%2Fopenhab-2.0.0.zip) or the latest Snapshot Version [![Download](https://api.bintray.com/packages/openhab/mvn/openhab-distro/images/download.svg?version=2.1.0)](https://openhab.ci.cloudbees.com/job/openHAB-Distribution/lastSuccessfulBuild/artifact/distributions/openhab/target/openhab-2.1.0-SNAPSHOT.zip) of openHAB2.

2.  Unzip the file in your chosen directory (e.g. `C:\openHAB2`)

    ![openHAB 2 Folders](images/openHAB_2_Folders.png)

3.  Start the server: Launch the runtime by executing the script `C:\openHAB2\start.bat` and wait a while for it to start and complete.

    ![Karaf_Windows](images/Karaf_Windows.png)

4.  Point your browser to `http://localhost:8080`.
    You should be looking at the openHAB [package selection page]({{base}}/configuration/packages.html).
    When you've selected an appropriate package, this page will contain the [UI]({{base}}/addons/uis.html) selection screen.

### File Locations

Assuming a successful install, you will now have various folders inside `C:\openHAB2`:

|                                  | Windows Installation         |
|:--------------------------------:|:-----------------------------|
| openHAB application              | `C:\openHAB2\runtime`        |
| Additional add-on files          | `C:\openHAB2\addons`         |
| Site configuration               | `C:\openHAB2\conf`           |
| Log files                        | `C:\openHAB2\userdata\logs`  |
| Userdata like rrd4j databases    | `C:\openHAB2\userdata`       |
| Service configuration            | `C:\openHAB2\userdata\etc`   |


## Backup

Make sure that you make regular backups of the **conf** and **userdata** folders, you can zip and unzip these folders too and from openHAB installations (even across most versions).
When you have a setup that you are happy with, it would be a good idea to make a backup of the whole `C:\openHAB2` folder.
Which can be used any time after a failure.

## Updating the openHAB Runtime

There is currently no automatic update script for Windows.
To update manually, download a later version of the openHAB distribution zip file and follow these steps:

1. Stop the openHAB process if it is currently running.
2. Backup openHAB as described above.
3. Delete the following files from your existing install:
   - `userdata\etc\all.policy`
   - `userdata\etc\branding.properties`
   - `userdata\etc\branding-ssh.properties`
   - `userdata\etc\config.properties`
   - `userdata\etc\custom.properties`
   - `userdata\etc\distribution.info`
   - `userdata\etc\jre.properties`
   - `userdata\etc\profile.cfg`
   - `userdata\etc\startup.properties`
   - Any file in `userdata\etc` that starts with `org.apache.karaf`
   - The `userdata\cache` folder
   - The `userdata\tmp` folder
4. Copy and paste the new `userdata` folder over your existing install, when prompted **do not overwrite existing files**
5. Copy and paste the new `runtime` folder over your existing install, when prompted **overwrite all existing files**

## Starting openHAB as a Service

By installing the openHAB process as a service in Windows, you can:

* Launch it automatically upon system startup
* Run it in the background

**Windows Service Installation Steps**

1.  Complete the [prerequisites](#prerequisites) and regular [installation](#installation) steps, including the package selection

2.  Issue the following two commands in your openHAB console:
    ```shell
    feature:install service-wrapper
    wrapper:install --name "openHAB2" --display "openHAB2" --description "openHAB 2 Service"
    ```

3.  Shutdown the openHAB instance by typing `logout` in the currently running console.

4.  Update the newly created `C:\openHAB2\userdata\etc\openHAB2-wrapper.conf` to include all necessary parameters.

    * Copy all the config text from the below section and paste it in your `openHAB2-wrapper.conf`, replacing all existing content.
    * Adapt the first entry (`OPENHAB_HOME`) to match your openHAB installation directory.

    ```conf
    #*******************************************************
    # openHAB2-wrapper.conf for Windows Service Installation
    #*******************************************************
    
    # openHAB installation dir (Adapt this first setting to your system)
    set.default.OPENHAB_HOME=C:\openHAB2

6.  Your openHAB Windows service is now installed and running.
    Validate proper operations by:

    * Browsing to [http://localhost:8080](http://localhost:8080)
    * Verifying that the Windows Service is running and set to Automatic Startup type.
      Use `services.msc` and find the `openHAB2` service.
      ![Windows Service](images/Windows_Service.jpg)
    * Logging in with an SSH client to the console (see info below)

### Connecting to the openHAB console

* Install an SSH client application, e.g., [Putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html), [KiTTY](http://kitty.9bis.net/) or [Xshell 5](https://www.netsarang.com/products/xsh_overview.html)
* Setup a session with the following parameters:
  * Host: 127.0.0.1
  * Port: 8101
  * Username: `openhab`
  * Password: `habopen`
