The goal of this getting started guide is to install Hass.io on a Raspberry Pi 3. Hass.io is our own all in one solution that turns your Raspberry Pi into the ultimate home automation hub.
Follow this guide if you want to easily get started with Home Assistant, or if you have no or little Linux experience. For advanced users or if you have no Raspberry Pi at hand, check our alternative installation methods. The FAQ explains more about the differences.
Please remember to secure your installation once you’ve finished with the installation process.
We will need a few things to get started with installing Home Assistant. Links below are linking to Amazon US. If you’re not in the US, you should be able to find these items in web stores in your country.
- Raspberry Pi 3 model B + Power Supply (at least 2.5A)
- Micro SD Card. Get one that is Class 10 as they are more reliable. Size 32 GB or bigger recommended.
- SD Card reader. Part of most laptops, and also available as standalone USB sticks (the brand doesn’t matter, just pick the cheapest)
- Ethernet cable (optional, Hass.io can work with WiFi too)
Support for the Raspberry Pi 3 model B+ is available in the alternative installation method Hassbian. The recently released Raspberry Pi 3 model B+ is not yet supported by Hass.io.
- Download Hass.io image for Raspberry Pi 3
- Download Etcher to write the image to an SD card
- Text Editor like Visual Studio Code
- Put the SD card in your SD card reader.
- Open Etcher, select the Hass.io image and flash it to the SD card.
- WiFi setup only: open the file

ssidto be your network name and
pskto be your password. Note: When connecting to a 5 GHz-only network, make sure your device supports that. If you don’t know what that means, then you probably have nothing to worry about.
- Unmount the SD card and remove it from your SD card reader.
- Insert the SD card into your Raspberry Pi 3. If you are going to use an Ethernet cable, connect that too.
- Connect your Raspberry Pi to the power supply so it turns on.
- The Raspberry Pi will now boot up, connect to the Internet and download the latest version of Home Assistant. This will take about 20 minutes. Do not expect anything but the Home Assistant logo on the HDMI display, or any use for a keyboard or mouse.
- Home Assistant will be available at http://hassio.local:8123. Shortly after the download has started, a simple preparation status page will be available at this URL. Point your browser there. The page refreshes automatically, and Home Assistant will be shown when the download is complete.
When you’re done, remember to set up regular backups of your configuration. This will protect you from hardware failure and mistakes. On Hass.io you have snapshots, but you can back up to GitHub, DropBox and many other ways. All that matters is that you set them up and test them regularly.
