How to Install OpenHAB on Fedora CoreOS Latest

OpenHAB is an open-source home automation platform that enables communication between devices from different manufacturers. Fedora CoreOS is a container-focused operating system. Installing OpenHAB on Fedora Core OS requires several steps that we will outline in this tutorial.

Prerequisites

  • Installed Fedora Core OS
  • Root access
  • Basic knowledge of Linux commands

Step-by-Step Guide

Step 1: Launch Terminal

  • Open the terminal from the installed Fedora Core OS.

Step 2: Install Java

  • OpenHAB requires Java to function correctly. Install Java with the following command in the terminal:
sudo dnf install java-11-openjdk-devel

Step 3: Download Latest OpenHAB package

  • In the terminal, create a new directory for OpenHAB, download the latest OpenHAB package from the OpenHAB website and extract it with the following commands:
sudo mkdir /opt/openhab
cd /opt/openhab 
sudo wget https://bintray.com/openhab/mvn/download_file?file_path=org%2Fopenhab%2Fdistro%2Fopenhab%2F2.5.12%2Fopenhab-2.5.12.zip
sudo unzip download_file?file_path=org%2Fopenhab%2Fdistro%2Fopenhab%2F2.5.12%2Fopenhab-2.5.12.zip

Note: Replace the version number with the latest version available for download.

Step 4: Configure User Permissions

  • Fedora Core OS uses the rootless mode by default, and OpenHAB requires access to some system resources. You need to add the user openhab to the required groups by running the following command in the terminal:
sudo useradd --system --user-group openhab
sudo usermod -G audio,video,storage openhab

Step 5: Start OpenHAB Service

  • Enable and start the OpenHAB service with the following commands in the terminal:
sudo /opt/openhab/userdata/bin/karaf
systemctl enable openhab.service --user openhab
systemctl start openhab.service --user openhab

Note: The first command, sudo /opt/openhab/userdata/bin/karaf, starts the Karaf console, which is the command-line interface of OpenHAB. Type logout to exit the Karaf console after the OpenHAB service starts.

Step 6: Check OpenHAB Status

  • Check the status of OpenHAB with the following command in the terminal:
systemctl status openhab.service --user openhab
  • Output:
● openhab.service - openhab
   Loaded: loaded (/home/openhab/.config/systemd/user/openhab.service; enabled; vendor preset: enabled)
   Active: active (running) since Wed 2021-10-06 15:07:44 EDT; 5s ago
