Raspberry Pi Options That I Recommend Avoiding

Are you on the hunt for a Raspberry Pi? That’s cool! While shopping around, you might see other options pop up. Don’t get me wrong, they’re all great products, but I wouldn’t recommend them for this specific project. The reason being, when you go to download that Home Assistant installer, you ain’t gonna find a match for these bad boys.

  • Raspberry Pi 2 Model B
  • Raspberry Pi 400
  • Raspberry Pi Zero, Zero 2, or Zero W

What Else Do You Need For This Setup?

Besides the Raspberry Pi, there are a few other things that you are going to need to set this configuration up:

How to Install Home Assistant On A Raspberry Pi 4

Once you have everything you need, you are ready to get through this Home Assistant Raspberry Pi tutorial. This will take you through the best way to install home assistant on Raspberry Pi and get it up and running as quickly and efficiently as possible.

Download the required software.

There are two pieces of software you will need to download – The Home Assistant installer image file from and Etcher from Home Assistant is obviously the Home Assistant software, and Etcher is the software used to load Home Assistant onto your SD card.

Flash SD card.

Insert your SD card into your card reader and connect it to your PC. Open Etcher and find the Home Assistant image in your downloaded folder. Then click “Select Drive” to choose the SD card. Then click “Flash.” It will take a few minutes to Flash the card, and you may get messages that you need to reply “Yes” to.

Install Home Assistant on your Raspberry Pi.

Take the SD card from the card reader and insert it into your Raspberry Pi. Connect the Pi to power and your network and boot it up. Over about the next 15-20 minutes, Home Assistant will install itself on your Pi. It will likely reboot itself once or twice during the process as well. Connecting a monitor to your Raspberry Pi can watch the progress by opening homeassistant.local:8123.

Configure Home Assistant.

Once the installation is complete, you are prompted to create a username and password to create your account. After this is done, you will want to set things like your time zone, elevation, name, etc. After you do this, click the finish button to pull up your dashboard and start using it.

Some Add-Ons That I Would Recommend

After you have it up and running, there are some add-ons that you can quickly install to help with various things in your Home Assistant installation. To find the Add-ons section, click the Supervisor link on the bottom left of the dashboard screen. Then click the “Add-on store” tab link.

  • Duck DNS – allows you to have a free dynamic DNS. Set it to start on boot. You will also need a Duck DNS account to get a token code – you add this token code and domain to the configuration section for the add-on. Be sure to click start after you have configured it.
  • Let’s Encrypt – creates an SSL certificate to make your installation more secure. When you click install on this add-on, you will also see a Documentation link that gives you complete instructions on installing it properly.
  • Samba Share – This allows you to access Home Assistant’s file system using your PC. When installing, you will need to define your host IP, user, and password in the configuration section.

Running Home Assistant on Raspberry Pi vs. PC

So, you’re wondering about the difference between running Home Assistant on a PC versus a Raspberry Pi, huh? Well, let me break it down for you.

Truth is, it’s not much different, but the PC version gives you an edge with more processing power and memory, so you can run all the apps you want all at once. But, at the end of the day, both options will get the job done just fine.

Let’s talk about why using a Raspberry Pi instead of a PC might be the way. The little guy may be petite, but it packs a punch!

  • Performance – a Raspberry Pi has plenty of performance for this application, and you would likely run most applications with it. It is also pretty cheap to get one of these compared to a PC as an alternative, which makes it easier to experiment without spending a lot of money on it.
  • Portability – With a Pi, you can move it around from location to location pretty quickly if you want to do so.
  • Dedicated platform – you are not tying up a full PC for your home automation setup, which is nice because you can use it for other purposes while doing your home automation setup.
  • Low cost.


Home Assistant, how many devices are on Raspberry Pi?

The number of devices you can control with a Raspberry Pi Home Assistant installation depends on how much processing power you have available in your setup and how complex you want things to be.

The more processing power you have and the more RAM you have available, the more devices you can control simultaneously without lag or slowdowns. That being said, even on a low-budget setup like the one I have here, I can handle about a half dozen devices and have some room to add more if I want.

Can Home Assistant run without Raspberry Pi? 

Yes, Home Assistant can run on other pieces of hardware other than a Raspberry Pi. These include a PC, ODroid N2+, Intel NUC, etc.


I hope you found this tutorial helpful and that it gets you up and running with setting up your first Home Assistant home automation system using a low-cost device like a Raspberry PI. It is a fun project to start in home automation, and it opens things up quite a bit once you get it running and configure some add-ons for it.
