Homeassistant Raspberrypi 4

Introduction

Quick wrap up of how to install HomeAssistant on a fresh RaspberryPi OS (32-bit) install. Source

Setup

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, hassio_supervisor.

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, http://localhost:8123.

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!

Next Steps

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.

Finally, 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.
