Homeassistant Raspberrypi 4
Quick wrap up of how to install HomeAssistant on a fresh RaspberryPi OS (32-bit) install. Source
First, setup your OS and update to the newest point by running the following:
sudo apt update sudo apt upgrade -y
Once everything is up to date, we can begin installing prerequisites.
add-apt-repository universe apt-get install -y apparmor-utils apt-transport-https avahi-daemon ca-certificates curl dbus jq network-manager socat software-properties-common curl -sSL https://get.docker.com | sh
Then we have to disable ModemManager
systemctl disable ModemManager apt-get purge modemmanager
And finally, we can run the HomeAssistant provided install script for the Docker based installation:
curl -sL "https://raw.githubusercontent.com/home-assistant/hassio-installer/master/hassio_install.sh" | bash -s
This is no longer an officially supported install method, but works great for me still
Once this is run through you will find one lonely docker container,
This container will begin pulling and setting up the remaining containers for hassio, including the audio server, dns, etc.
You can watch the progress by running,
sudo docker logs -f hassio_supervisor.
Once all of the following containers are up and running, you can visit port
8123 on your pi's IP.

So in my example,
This will bring up the "Preparing Home Assistant" screen. This process actually does take a while, so at this point maybe go have a smoke or make another coffee..
After the setup is done doing its thing, you will be presented with a User setup form.
Enter your chosen Name, Username, and Password.
Then you will be asked to name your instance, confirm your location, and a few other settings.
Finally you can setup some of the autodetected devices on your network and then you're in!
At this point I would recommend installing the Hassio Google Drive Backup addon.
Available here: sabeechen/hassio-google-drive-backup.
To restore a snapshot, login with your Google credentials and download your latest available snapshot.
scp that snapshot onto your pi to
/usr/share/hassio/backup. You will then find it in the HomeAssistant UI under 'Supervisor' -> 'Snapshots' where you can wipe and restore to that snapshot.
