1. Update the system
$ sudo apt-get update $ sudo apt-get upgrade -y
2. Install the dependencies
sudo apt-get install python3 python3-venv python3-pip
3. Add an account for Home Assistant called homeassistant
$ sudo useradd -rm homeassistant -G dialout,gpio
4. Create a directory for the installation of Home Assistant
$ cd /srv
$ sudo mkdir homeassistant
$ sudo chown homeassistant:homeassistant homeassistant
5. Create and Change to a Virtual environment for Home Assistant
$ sudo -u homeassistant -H -s $ cd /srv/homeassistant $ python3 -m venv . $ source bin/activate
pi@raspberrypi:/srv/homeassistant $ source bin/activate
(homeassistant) pi@raspberrypi:/srv/homeassistant $
6. Once activated the virtual environment, Install a required python package
(homeassistant) homeassistant@raspberrypi:/srv/homeassistant $ python3 -m pip install wheel
7. Now it's time to Install Home Assistant
(homeassistant) homeassistant@raspberrypi:/srv/homeassistant $ pip3 install homeassistant
8. Create /home/homeassistant/.homeassistant configuration directory

automations.yaml custom_components deps groups.yaml home-assistant_v2.db scripts.yaml tts
configuration.yaml customize.yaml entity_registry.yaml home-assistant.log known_devices.yaml secrets.yaml
(homeassistant) pi@raspberrypi:/home $
9. Run hass, And you can reach your installation on your Raspberry Pi over the web interface on http://ipaddress:8123
(homeassistant) pi@raspberrypi:/home $ hass
10. When you login in you pi system, before you run hass, you should change to the virtual environment
