Saw the announcement yesterday for HASSbian 1.21 and got super excited?

Today we’ll flash the latest HASSbian to a Raspbery Pi Zero W. With an added bonus that besides for an USB cable for power, there’s no need for any cables!

What you’ll need:

  • a Raspberry Pi Zero W (an amazing tiny computer with built-in wifi)
  • a microSD card
  • some source of USB power
  • Wifi
  • a desktop or laptop

Let’s get to it!

First, download the HASSbian 1.21 image from here.

Unzip it.

Flash it to the microSD card. If you need a flash tool, try Etcher

When the flashing finishes, remove it and plug it back in. You should see a drive called “boot”.

Right in there, not in any folders, create a file called wpa_supplicant.conf.

The contents of the configuration file should be something like this: (You may have to adjust for your configuration, hints here )

network={
    ssid="YOUR_WIFI_NETWORK_NAME_HERE"
    psk="YOUR_WIFI_PASSWORD_HERE"
    key_mgmt=WPA-PSK
}

Next stick your SD card into the Raspberry Pi Zero W, and plug it in.

After about a minute, use your SSH client to connect to HASSbian (or hassbian.local from a Mac), with the username pi. The default password is raspberry.

It’s a good idea to change the password. To do so, use the passwd command.

Next, type the following two commands into the SSH console:

$ sudo systemctl enable install_homeassistant.service
$ sudo systemctl start install_homeassistant.service

Wait about 15-20 minutes and voilà you have your Home Assistant on your Raspberry Pi Zero W in 30 minutes.

To try it out, go to http://hassbian:8123 or http://hassbian.local:8123 if you’re using Mac.

For further details about HASSbian, take a look at the documentation.
