Home Assistant Windows

Are you ready to transform your home into a smart haven? Look no further than Home Assistant—a powerful and versatile platform that allows you to automate various aspects of your home, making it more convenient and efficient.

In this comprehensive guide, I will walk you through the process of installing and configuring a Home Assistant Windows instance, enabling you to take full advantage of its incredible features and turn your ordinary house into a futuristic, intelligent dwelling.

Introduction to Home Assistant

Home Assistant is an open-source home automation platform that enables you to control and monitor various devices and services in your home. It serves as a centralized hub, allowing you to integrate smart devices from different manufacturers and manage them through a single interface. With Home Assistant, you can automate routines, create complex scenarios, and monitor the state of your home from anywhere in the world.

Does Home Assistant Work on Windows?

Home Assistant can not be installed directly onto a Windows operating system.

If you need to have an instance of Home Assistant on Windows the best option is to install Home Assistant OS in a virtual machine on your Windows device.

You may want to do this because you don't have any spare hardware to install Home Assistant OS directly on, or you would like a test instance of Home Assistant for experimenting with.

Later in this article, I will guide you step-by-step on installing a Home Assistant Windows VM and getting up and running with USB redirection to allow devices such as a Z-Wave dongle to communicate with Home Assistant.

The recommended Windows platform would be Windows Server 2016+, Windows 10/11 will work but these operating systems are not designed to run 24/7.

Benefits of Home Assistant for Windows Users

For Windows users, Home Assistant provides a seamless and user-friendly experience. Whether you are a tech enthusiast or a beginner, setting up Home Assistant on your Windows machine offers several advantages:

  • Compatibility: Home Assistant supports a wide range of devices and protocols, ensuring compatibility with your existing smart home ecosystem.

  • Flexibility: The platform is highly customizable, allowing you to tailor your smart home automation to your specific needs and preferences.

  • Community Support: Home Assistant has a vibrant community of users and developers who actively contribute to its development, ensuring continuous improvement and support.

  • Integration: Home Assistant integrates with popular platforms like Google Assistant, Amazon Alexa, and Apple HomeKit, providing a unified control experience across multiple devices and voice assistants.

  • Privacy and Security: With Home Assistant running locally on your Windows machine, you have full control over your data and can ensure the highest level of privacy and security.

System Requirements

Before installing Home Assistant, ensure that your Windows machine meets the following system requirements:

  • Operating System: Windows 10 (64-bit) or Windows Server 2016 (64-bit) or later versions.

  • Processor: Intel Pentium 4 / AMD Athlon 64 or newer with support for SSE3.

  • RAM: 8GB or higher.

  • Storage: At least 10GB of free disk space.

  • Network: A stable internet connection for initial setup and remote access.

Home Assistant Windows Installation Steps

You can create your Home Assistant VM in either Oracle VirtualBox, Hyper-V, or VMWare Workstation.

In this article, I will be using Oracle VirtualBox because it is completely free to use and is the most popular platform used by the Home Assistant community for Windows users.

Part 1 - Install Oracle VirtualBox

Oracle VirtualBox is a free and open-source virtualization software that allows users to run multiple operating systems on a single computer. It creates virtual machines that mimic the hardware and software of a physical computer.

Go to https://www.virtualbox.org/wiki/Downloads and click the download link for "Windows hosts" to download and run the exe installer.

Click next

Ensure VirtualBox USB Support and VirtualBox Networking are enabled and click next

Click Yes to accept brief network interruption during the installation.

Click Yes to proceed with installation, we won't be using Python here so we can ignore the warning.

Click Install then Finish to complete the VirtualBox installation!

Part 2 - Install Home Assistant OS in a VirtualBox VM

To install Home Assistant on your Windows machine you will need to download a Home Assistant OS image and install this image in a VirtualBox virtual machine. Follow these steps to complete the process:

Visit the official Home Assistant website at https://www.home-assistant.io/installation/windows and click on the VirtualBox link to download the ZIP archive.

Extract the downloaded ZIP file then open up VirtualBox.

Click on New to begin creating a VM.

Give your new VM a name, set the VM type to Linux then the version to Linux 2.6 / 3.x / 4.x / 5.x (64-bit)

On the hardware screen give the VM at least 2GB of memory and tick the Enable EFI box.

For the virtual hard disk we need to select Use an Existing Virtual Hard Disk File and browse to where you extracted the Home Assistant OS file from the ZIP file downloaded earlier.

On the summary page, review your settings and click Finish.

From the main VirtualBox GUI right click on your VM and select Settings.

Go to the Network section and change the drop-down option to Bridged Adapter.

If you have a USB dongle such as a Bluetooth adapter, Zigbee or Z-Wave stick then go to the USB section and click the button on the right with the green plus sign then choose your adapter so that it appears in the USB Device Filters list.

In the screenshot below I have added an AEOTEC Z-Wave USB dongle, this shows up in the list as "Sigma Designs, Inc".

You can now close the settings page and start up your Home Assistant VM. Open the console to view the boot process and make a note of the IP address it picks up.
