- Download the operating system from the link above.
- Attach the drive you are using in your NUC to your computer.
- Download and start Balena Etcher
- Select “Flash from File” and choose the image you have just downloaded.
- Click “Select Target” and choose the drive you wish to flash too, then click “Flash”.
- Start the NUC with the drive you installed the operating system to as the boot device.
- Once the initial setup has completed you will be able to reach Home Assistant on homeassistant.local:8123. If you are running an older Windows version or have a stricter network configuration, you might need to access Home Assistant at homeassistant:8123 or
http://X.X.X.X:8123(replace X.X.X.X with your ’s IP address).
With the Home Assistant Operating System installed and accessible you can continue with onboarding.
These below instructions are for an installation of Home Assistant Container 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.
This guide assumes that you already have an operating system setup and a container runtime installed (like Docker).
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.
docker run --init -d \ --name homeassistant \ --restart=unless-stopped \ -v /etc/localtime:/etc/localtime:ro \ -v /PATH_TO_YOUR_CONFIG:/config \ --network=host \ homeassistant/home-assistant:stable
# if this returns "Image is up to date" then you can stop here docker pull homeassistant/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 --init -d \ --name homeassistant \ --restart=unless-stopped \ -v /PATH_TO_YOUR_CONFIG:/config \ -v /etc/localtime:/etc/localtime:ro \ --network=host \ homeassistant/home-assistant:stable
Once the Home Assistant Container is running Home Assistant should be accessible using
If you change the configuration you have to restart the server. To do that you have 3 options.
- In your Home Assistant UI go to the Configuration panel -> Server management and click the “Restart” button.
- You can go to the Developer Tools -> Services, select the service
homeassistant.restartand click “Call Service”.
- Restart it from a terminal.
docker restart homeassistant
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
version: '3' services: homeassistant: container_name: homeassistant image: homeassistant/home-assistant:stable volumes: - /PATH_TO_YOUR_CONFIG:/config - /etc/localtime:/etc/localtime:ro restart: unless-stopped network_mode: host
Start it by running:
docker-compose up -d
In order to use Z-Wave, 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 run ... --device /dev/ttyUSB0:/dev/ttyUSB0 ...
version: '3' services: homeassistant: ... devices: - /dev/ttyUSB0:/dev/ttyUSB0
The Home Assistant Container is using an alternative memory allocation library jemalloc for better memory management and Python runtime speedup.
As jemalloc can cause issues on certain hardware, it can be disabled by passing the environment variable
DISABLE_JEMALLOC with any value, for example:
docker run ... -e "DISABLE_JEMALLOC=true" ...
version: '3' services: homeassistant: ... environment: DISABLE_JEMALLOC: true
The error message
<jemalloc>: Unsupported system page size is one known indicator.
This guide assumes that you already have an operating system setup and have installed Python 3.8 (including the package
python3-dev) or newer.
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 libffi-dev libssl-dev libjpeg-dev zlib1g-dev autoconf build-essential libopenjp2-7 libtiff5 tzdata
Add an account for Home Assistant Core called
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.
sudo useradd -rm homeassistant
First we will create a directory for the installation of Home Assistant Core and change the owner to the
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
sudo -u homeassistant -H -s cd /srv/homeassistant python3.8 -m venv . source bin/activate
Once you have activated the virtual environment (notice the prompt change to
(homeassistant) [email protected]:/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
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.
You can now reach your installation via the web interface on
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 “site cannot be reached” error when accessing the web interface. This will only happen for the first time, and subsequent restarts will be much faster.
