Its architecture is quite impressive as it is developed in Java and more of an Eclipse Smart Home framework. This offers you a vast number of devices where you can run the system. Moreover, it provides a runtime environment that uses Apache Karaf alongside Eclipse Equinox to set up an Open Services Gateway initiative.

To add on to this, the OpenHAB’s architecture has the extension of additional features that are believed to expand its functionalities. Intuitive user interfaces provide the ability to easily interact with a sheer number of physical things. This allows more capabilities options of the OpenHAB. Also, OpenHAB has a pluggable feature that supports a good number of different technologies and systems as well as thousands of devices.

Furthermore, OpenHAB is capable of running on various platforms like Linux, Windows and Mac OSx as well. It can also run on Raspberry Pi, Docker, PINE64, and Synology among other numerous platforms. Most people are having a good experience installing the OpenHAB on Raspberry Pi, this might also be feasible for you.

Home Assistant, on the other hand, is a home automation platform running on Python 3 under the Apache 2.0 license. It is powered by DIY enthusiasts and a worldwide of tinkerers to ensure a smart home control with privacy concerns. It also perfectly runs on a Raspberry Pi platform just like OpenHAB or any other local server.

Home Assistant also has an incredible operating system referred to as Hass.io. This plays a very important role in installing and updating Home Assistant. As it is managed from the frontend, the Home Assistant user interface allows the creation or restoration of snapshots of your configuration.

Moreover, there is the ability to extend the Hass.io add-on features like the Duck DNS, Let’s Encrypt, as well as Google Assistant among others. This provides you with the additional functionalities that come in handy with the add-on features. The Home Assistant also has several amazing resources including the additional software, custom components, Lovelace panels and much more.

The architecture of Home Assistant has home control feature which is responsible for collecting information and controlling devices. It also has Home Automation which triggers commands based on user configurations. In addition to this is the Smart Home which triggers commands based on the previous behavior.

Home Assistant Vs OpenHAB: Installation and Configuration

The installation and configuration process is pretty simple and easy to follow for both Home Assistant and OpenHAB. We recommend you to install the software on a Raspberry Pi which is cheap and scalable.

For OpenHAB, the installation process will consume between 20 and 30 minutes of your time and it is just straightforward. The configuration process is usually done using the web interface by following the installation guide provided on the website.

The installation process for Home Assistant is just as simple as that for OpenHAB. However, you will need to download and burn the image of HassBian. Be sure to have a stable internet connection so that the process may be smooth and without problems. The getting started guide is provided in the Home Assistant webpage, therefore, achieving the installation process would be much simpler with the guide.

In terms of configuration, the latest version of OpenHAB has the paper UI and the Web UI. This allows you to perform several configurations without the need to edit files. However, the paper UI does not support all features in the OpenHAB, therefore, you will need to edit files to achieve the configuration.

The Home Assistant performs the configuration by making decisions on behalf of the user. This happens during the first time it runs as it automatically discovers all devices that are in your house and then add them to the UI. There is also an option for YAML which is used to configure files, blueprints as well as page settings.

The Home Assistant proves to be the best by having certain capabilities that the OpenHAB does not. The add-on feature in Home Assistant makes it impressive due to the widespread documentation and the one-click installation process. Also, it does not require you to use command line during installation and configuration as this can be quite involving and demanding too.

Home Assistant Vs OpenHAB: Flexibility

Talking of flexibility, OpenHAB can be as flexible as you would want it to be but this comes at a cost. The system is not that easy to use as there are so many efforts needed in the configuration of files. The Web UI supports various basic things, however, the mixed-up configurations might be cumbersome to the users. This considers it a little bit flexible.

On the other side, the Home Assistant is known to quench the thirst of many users. This is due to the presence of the auto-discovery function which works pretty well. Another great feature of this system is the ability to predict or guess the needs of the user. With this, Home Assistant is believed to be flexible in a way that it can suit the desires of many users.

Home Assistant Vs OpenHAB: Automation

There are several ways in which you can control and manage automation rules. For Home Assistant, there is the use of YAML (YAML Ain’t Mark-up Language). This is a human-friendly standard for all programming languages. Using the Python style indentations, YAML proves to be a good way to create automation rules however, it can be hard to use for novice users.

Also, there is a built-in automation editor that allows beginners to easily create and edit automation rules. This is an alternative to YAML which seems to be unforgiving to the beginners. It is, therefore, easy to use but it still requires a better understanding of the entity names and service calls concept.

Furthermore, Home Assistant also uses the Node-RED to manage the automation rules. This tool is visual, quick to change and to deploy, therefore, offering great flexibility. Node-RED was originally developed by IBM as a flow-based development tool for visual programming. Also, App-daemon is another powerful tool used by Home Assistant which uses Python abilities to manage automation rules. Python is quite easy and quick to learn as you can be able to perform complex tasks with just a few lines of code.

The OpenHAB is most likely to handle anything that you want it to while considering the Xbase syntax which is easy to deal with. It also has a good number of built-in tools for managing automation rules. This includes the use of Xtend which is a supple and meaningful language of Java that compiles into readable Java 8 compatible source.
