Generic x86-64

Install Home Assistant Operating System

Follow this guide if you want to get started with Home Assistant easily or if you have little to no Linux experience.

Configure the BIOS on your x86-64 hardware

To boot Home Assistant OS, the BIOS needs to have UEFI boot mode enabled and Secure Boot disabled. The following screenshots are from a 7th generation Intel NUC system. The BIOS menu will likely look different on your system. However, the options should still be present and named similarly.

1. To enter the BIOS, start up your x86-64 hardware and repeatedly press the F2 key (on some systems this might be Del, F1 or F10).

2. Make sure the UEFI Boot mode is enabled.

3. Disable Secure Boot.

4. Save your changes and exit.

The BIOS configuration is now complete.

Write HAOS onto your x86-64 hardware

Next, you need to write the Home Assistant Operating System image to the boot medium, which is the medium your x86-64 hardware will boot from when it is running Home Assistant.

Typically, an internal medium like S-ATA hard disk, S-ATA SSD, M.2 SSD, or a non-removable eMMC is used for the x86-64 boot medium. Alternatively, an external medium can be used such as a USB SDD, though this is not recommended.

To write the HAOS image to the boot medium on your x86-64 hardware, there are 2 different methods:

Method 1 (recommended): Boot Ubuntu from a USB flash drive and install the Home Assistant Operating SystemHome Assistant OS, the Home Assistant Operating System, is an embedded, minimalistic, operating system designed to run the Home Assistant ecosystem. It is the recommended installation method for most users. [Learn more] from there. It also works on laptops and PCs with internal hard disks.

Method 2: With this method, you write the Home Assistant Operating disk image directly onto a boot medium from your regular computer. The steps are a bit more complex. If you have non-removable internal mediums (for example because you are using a laptop) or do not have the necessary adapter (for example an USB to S-ATA adapter) use method 1 instead.

   • This means you will lose all the data as well as the previously installed operating system.
   • Back up your data before carrying out this procedure.
2. Create a live operating system on a USB flash drive:
   • Follow the Ubuntu instructions on writing an Ubuntu iso file onto a USB device.
3. Insert the USB flash drive into the system on which you want to run Home Assistant.
   • Boot the live operating system.
   • You might need to adjust boot order or use F10 (might be a different F-key depending on the BIOS) to select the USB flash drive as boot device.
4. When prompted, make sure to select Try Ubuntu. This runs Ubuntu on the USB flash device.
   • The system then starts Ubuntu.
   • Connect your system to your network and make sure it has internet access.
5. In Ubuntu, open a browser and open the current documentation page, so you can follow the steps.
   • From there, download the image.
6. In Ubuntu, in the bottom left corner, select Show Applications.
7. In the applications, search and open Disks and start restoring the HAOS image:
   1. In Disks, on the left side, select the internal disk device you want to install HAOS onto.
   2. On top of the screen, select the three dots menu and select Restore Disk Image….
   3. Select the image you just downloaded.
   4. Select Start Restoring….
   5. Confirm by selecting Restore.
      • If you are getting an Error unmounting filesystem error message, stating that the target is busy:
      • Most likely, you are running Ubuntu on your internal disk. Instead, you need to run it on your stick.
        • Go back to step 3 and during start up, make sure you select Try Ubuntu (and NOT Install Ubuntu).
   6. In the partitions overview, you should now see the restore operation in progress.
      • The Home Assistant Operating System is now being installed on your system.
8. Once the Home Assistant Operating System is installed, shut down the system.
   • Once Ubuntu has been shut down, remove the USB flash drive (Ubuntu will inform you when this is the case).
   • Your Home Assistant server is now set up and you can start using it.
   • To use it, proceed as described under start up your generic x86-64.

5. Paste the URL into your browser to start the download.
6. Extract the file you just downloaded.
7. Select Flash from file and select the image you just extracted.
   • Do not use Flash from URL. It does not work on some systems.

8. Select target. 9. Select the boot medium (storage device) you want to use for your installation. 10. Select Flash! to start writing the image.

• If the operation fails, decompress the .xz file and try again.
• When Balena Etcher has finished writing the image, you will see a confirmation.

Start up your Generic x86-64

• If you used method 1 for the installation, make sure the USB flash drive is removed from the system.

• If you used method 2 for the installation, install the boot medium into your x86-64 hardware.

1. Plug in an Ethernet cable that is connected to the network and to the internet.
   • Note: Internet is required because the newly installed Home Assistant OS does not contain all Home Assistant components yet. It downloads the latest version of Home Assistant Core on first start.
2. Power the system on. If you have a screen connected to the Generic x86-64 system, after a minute or so the Home Assistant welcome banner will appear in the console.

efibootmgr --create --disk /dev/<drivename> --part 1 --label "HAOS" \
   --loader '\EFI\BOOT\bootx64.efi'

\EFI\BOOT\bootx64.efi

3. In the browser of your desktop system, within a few minutes you will be able to reach your new Home Assistant at homeassistant.local:8123.

With the Home Assistant Operating System installed and accessible, you can continue with onboarding.

Install Home Assistant Container

These below instructions are for an installation of Home Assistant ContainerHome Assistant Container is a standalone container-based installation of Home Assistant Core. Any OCI compatible runtime can be used, but the documentation focus is on Docker. [Learn more] running in your own container environment, which you manage yourself. Any OCI compatible runtime can be used, however this guide will focus on installing it with Docker.

Platform installation

Installation with Docker is straightforward. Adjust the following command so that:

• /PATH_TO_YOUR_CONFIG points at the folder where you want to store your configuration and run it. Make sure that you keep the :/config part.

• MY_TIME_ZONE is a tz database name, like TZ=America/Los_Angeles.

• D-Bus is optional but required if you plan to use the Bluetooth integration.

  Install

  Update

  docker run -d \
    --name homeassistant \
    --privileged \
    --restart=unless-stopped \
    -e TZ=MY_TIME_ZONE \
    -v /PATH_TO_YOUR_CONFIG:/config \
    -v /run/dbus:/run/dbus:ro \
    --network=host \
    ghcr.io/home-assistant/home-assistant:stable
  

  # if this returns "Image is up to date" then you can stop here
  docker pull ghcr.io/home-assistant/home-assistant:stable
  

  # stop the running container
  docker stop homeassistant
  

  # remove it from Docker's list of containers
  docker rm homeassistant
  

  # finally, start a new one
  docker run -d \
    --name homeassistant \
    --restart=unless-stopped \
    --privileged \
    -e TZ=MY_TIME_ZONE \
    -v /PATH_TO_YOUR_CONFIG:/config \
    -v /run/dbus:/run/dbus:ro \
    --network=host \
    ghcr.io/home-assistant/home-assistant:stable
  

  Once the Home Assistant Container is running Home Assistant should be accessible using http://<host>:8123 (replace with the hostname or IP of the system). You can continue with onboarding.

    Onboarding

  Restart Home Assistant

  If you change the configuration, you have to restart the server. To do that you have 3 options.

  1. In your Home Assistant UI, go to the Settings > System and click the Restart button.
  2. You can go to the Developer Tools > Actions, select homeassistant.restart and select Perform action.
  3. Restart it from a terminal.
  Docker CLI

  Docker Compose

  docker restart homeassistant
  

  docker compose restart
  

  Docker compose

  Tip

  docker compose should already be installed on your system. If not, you can manually install it.

  As the Docker command becomes more complex, switching to docker compose can be preferable and support automatically restarting on failure or system restart. Create a compose.yml file:

    services:
      homeassistant:
        container_name: homeassistant
        image: "ghcr.io/home-assistant/home-assistant:stable"
        volumes:
          - /PATH_TO_YOUR_CONFIG:/config
          - /etc/localtime:/etc/localtime:ro
          - /run/dbus:/run/dbus:ro
        restart: unless-stopped
        privileged: true
        network_mode: host
  

  Start it by running:

  docker compose up -d
  

  Once the Home Assistant Container is running, Home Assistant should be accessible using http://<host>:8123 (replace with the hostname or IP of the system). You can continue with onboarding.

    Onboarding

  Exposing devices

  In order to use Zigbee or other integrations that require access to devices, you need to map the appropriate device into the container. Ensure the user that is running the container has the correct privileges to access the /dev/tty* file, then add the device mapping to your container instructions:

  Docker CLI

  Docker Compose

  docker run ... --device /dev/ttyUSB0:/dev/ttyUSB0 ...
  

  services:
    homeassistant:
      ...
      devices:
        - /dev/ttyUSB0:/dev/ttyUSB0
  

  Optimizations

  The Home Assistant Container is using an alternative memory allocation library jemalloc for better memory management and Python runtime speedup.

  As the jemalloc configuration used can cause issues on certain hardware featuring a page size larger than 4K (like some specific ARM64-based SoCs), it can be disabled by passing the environment variable DISABLE_JEMALLOC with any value, for example:

  Docker CLI

  Docker Compose

  docker run ... -e "DISABLE_JEMALLOC=true" ...
  

  services:
    homeassistant:
    ...
      environment:
        DISABLE_JEMALLOC: true
  

  The error message <jemalloc>: Unsupported system page size is one known indicator.

  Install Home Assistant Core

  Caution

  This is an advanced installation process, and some steps might differ on your system. Considering the nature of this installation type, we assume you can handle subtle differences between this document and the system configuration you are using. When in doubt, please consider one of the other installation methods, as they might be a better fit instead.

  Prerequisites

  This guide assumes that you already have an operating system setup and have installed Python 3.13 (including the package python3-dev) or newer.

  Install dependencies

  Before you start, make sure your system is fully updated, all packages in this guide are installed with apt, if your OS does not have that, look for alternatives.

  sudo apt-get update
  sudo apt-get upgrade -y
  

  Install the dependencies:

  sudo apt-get install -y python3 python3-dev python3-venv python3-pip bluez libffi-dev libssl-dev libjpeg-dev zlib1g-dev autoconf build-essential libopenjp2-7 libtiff6 libturbojpeg0-dev tzdata ffmpeg liblapack3 liblapack-dev libatlas-base-dev
  

  The above-listed dependencies might differ or missing, depending on your system or personal use of Home Assistant.

  Create an account

  Add an account for Home Assistant Core called homeassistant. Since this account is only for running Home Assistant Core the extra arguments of -rm is added to create a system account and create a home directory. The arguments -G dialout,gpio,i2c adds the user to the dialout, gpio and the i2c group. The first is required for using Z-Wave and Zigbee controllers, while the second is required to communicate with GPIO.

  sudo useradd -rm homeassistant -G dialout,gpio,i2c
  

  Create the virtual environment

  First we will create a directory for the installation of Home Assistant Core and change the owner to the homeassistant account.

  sudo mkdir /srv/homeassistant
  sudo chown homeassistant:homeassistant /srv/homeassistant
  

  Next up is to create and change to a virtual environment for Home Assistant Core. This will be done as the homeassistant account.

  sudo -u homeassistant -H -s
  cd /srv/homeassistant
  python3 -m venv .
  source bin/activate
  

  Once you have activated the virtual environment (notice the prompt change to (homeassistant) homeassistant@raspberrypi:/srv/homeassistant $) you will need to run the following command to install a required Python package.

  python3 -m pip install wheel
  

  Once you have installed the required Python package, it is now time to install Home Assistant Core!

  pip3 install homeassistant==2024.12.5
  

  Troubleshooting: If you do not see the above version of Home Assistant package in your environment, make sure you have the correct Python version installed, as defined under the Prerequisites.

  Start Home Assistant Core for the first time. This will complete the installation for you, automatically creating the .homeassistant configuration directory in the /home/homeassistant directory, and installing any basic dependencies.

  hass
  

  You can now reach your installation via the web interface on http://homeassistant.local:8123.

  If this address doesn’t work you may also try http://localhost:8123 or http://X.X.X.X:8123 (replace X.X.X.X with your machines’ IP address).

  Note

  When you run the hass command for the first time, it will download, install and cache the necessary libraries/dependencies. This procedure may take anywhere between 5 to 10 minutes. During that time, you may get a site cannot be reached error when accessing the web interface. This will only happen the first time. Subsequent restarts will be much faster.
