How to Install Home Assistant on Raspberry Pi?

To install the Home Assistant on your RPi, use these steps:

First, you need to download the latest version of Home Assistant OS from their official GitHub page. Make sure to download the correct file for your version of Raspberry Pi and the file name should end in .img.xz. Extract the file to a new folder in your PC.
Next, download and install Balena Etcher software corresponding to your computer’s operating system (Windows/ Mac/ Linux) for flashing the Home Assistant OS image to your SD card.
Now connect your SD card to the computer and format it. Make sure to backup all your require files before proceeding.
Once done with that, launch Etcher and click on the Flash from file button and choose the OS image file that we’ve extracted.
After that, click on the Select target button to choose the SD card on which you want to install the Home Assistant OS. If you have only one writable drive, Etcher will automatically select it as the target drive.
Now click on Flash! to start writing the OS image on your SD card. The process will take some time to complete depending on your system and drive speed. Once the process successfully completes, you will see a “Flash complete!” message.
Now, if you intend to use ethernet cable for internet connection, you can skip to step * But, if you want to connect your Raspberry Pi to Wi-Fi, a little tweaking is needed. For this, open the drive (hassos-boot) where you flashed the OS and there create a new folder named Config.
Within the Config folder, create another folder called network.
Inside the network folder, create a text file called my-network.
The extension of my-network file is now .txt. You need to remove the file extension as shown in the screenshots below.

Now, open the file my-network and add the below code.

[connection]
id=my-network
uuid=<UUID>
type=802-11-wireless

[802-11-wireless]
mode=infrastructure
ssid=<WIFISSID>
# Uncomment the below line if your SSID is not broadcasted
#hidden=true

[802-11-wireless-security]
auth-alg=open
key-mgmt=wpa-psk
psk=<WIFIPASSWORD>

[ipv4]
method=auto

[ipv6]
addr-gen-mode=stable-privacy
method=auto

Now, replace <UUID> with your new UIID. To generate a new UUID using an online UUID generator. Then replace <WIFISSID> with the SSID of your Wi-Fi network, and finally replace <WIFIPASSWORD> with the password of your network. Once done, save the file.
Eject the SD card from your system, insert it into your Pi and Power it on. Wait till the Home Assistant command line interface appears.
Now, open your browser and head to the following URL to get to the Home Assistant homepage.
```
http://homeassistant.local:8123
```
If the above URL doesn’t work for you, try accessing the following URL.
```
http://homeassistant:8123
```
If that too doesn’t get through, the final option is to use the below URL, but here you need to know Raspberry Pi’s IP address.
```
http://<IPADDRESS>:8123
```
Here, replace <IPADDRESS> with the IP address of your Raspberry Pi.
If you see an error message like “Site Can’t Be Reached” or something similar, wait for sometime and try again. It may take some time to download the latest version and set up everything for you.
Once done, you will see the following screen on your browser window.
The first thing you need to do is to create a new account to start using it. So, provide all necessary details and click CREATE ACCOUNT.
On the next screen, give a name to your Home Assistant installation and click NEXT.
Check all the boxes on the next screen and click NEXT.
Finally, click on FINISH to complete the process.
Once you do the above steps successfully, you will be take into the Home Assistant dashboard where you can add more integrations and start automating your home.

Conclusion

Overall, installing Home Assistant on a Raspberry Pi is a great way to get started with home automation. Not only is it easy to set up, but it’s also relatively inexpensive and customizable. Plus, plenty of projects and devices can be added to a home automation setup with Raspberry Pi. As home automation becomes more popular, it’s crucial to have a secure and easy system to use.
