Get started with the automation system

In the previous post I’ve covered pros and cons about having a home automation system in the house. Now I will cover how we can set up the system and get it running.



There are multiple ways to set Home automation up, but here I will only cover the way I’ve set it up.


First we need to collect all needed hardware and software we are gonna use. You can setup everything in place where you gonna have it in your house, but we have to install the home assistant software on the SD card first. So no need to rush and boot it up before this is done, you will get dissapointed if your’e expecting picture on your screen.


  • Raspberry Pi Model 3 B+
  • Power Supply (2.5 A)
  • Case for Raspberry Pi (optional but recommended)
  • Micro-SD card (32gb or bigger recommended)
  • USB-stick if your gonna setup WI-FI connection (a cheap one will do the trick)


OK, lets start!

1. Set up WI-FI for Home assistant (optional)



I’ve read some places that this step can be done later on, but I didn’t get this to work properly so i ended up wiping my installation and started all over again and started with this step.

If your’e gonna have the system cabled then you can skip this step, but nice to have i guess.

This is where the USB-stick comes in, we need to format this to FAT or EXFAT format and give it a new name «CONFIG». 
You can do this by using: 
Disk utility (mac)
Go to my computer -> right click on USB-stick and «format» (windows). 

After the USB-stick is formated we can now create directory for the configuration file for WIFI, the new directory is CONFIG/network 
In this folder we need to create a new file called «hassos-wifi» without any file extension.
Then you can copy paste the code under and replace SSID (WIFI-name) and PSK (WI-FI password) 

Now save the file and eject the USB-stick and insert it in the Raspberry PI.
Don’t boot the PI yet. 

2. Flash image to SD-card

Ok, now we are getting closer to getting the setup up running, now we need to open Etcher for flashing the image to the SD-card

The Etcher software is pretty straight forward, just simply select image that we downloaded, then select the SD-Card as drive and hit Flash!
The flashing can take some minutes..

When the flashing is done we can eject the SD-card and place it in the Raspberry PI and we can jump to the next step!

3. Start the install

Now as the USB-stick and SD-Card are ready and mounted to the Raspberry PI, we can plug the power cable in. After a few minutes (independent if its cabled or WI-FI) the Home Assistant should be able from http://hassio.local:8123 

If everything is set up right, you will get this message on your screen (this can take up to 20 minutes). When this is done we can go forward to the next step. 

3. Setup new account

When the preparing of is ready, then you will get a user registration form (username and password) for logging in to the system. As probably said many times, Its very recommended to have a strong password.

You can use to create a new password if you dont know what to use..

4. And your’e DONE! 

You should now be able to access the Home Assistant panel now, Great! Now we can start setting up our frontend setup and smart devices such as bulbs temperature monitors and so on. That you can read more about in one of my other articles.
