Set up Home Assistant Development Environment on Raspberry Pi

Last Updated on2021-05-14 03:32:18

Overview

This tutorial describes how to install Home Assistant Core on Raspberry Pi to get started with Home Assistant and set up the development environment.

Home Assistant is a Python-based open-source smart home system. It supports connection to smart devices across different platforms, which allows you to control a connected home with one system.
We use Home Assistant Core (recommended for developers) to install Home Assistant OS and runs the program in Ubuntu Server. For more information about other installation methods, see the instructions on Home Assistant.

    Prepare hardware and software

    Hardware/Software Description
    Computer A Mac computer
    Device to run Home Assistant Raspberry Pi 3 or later
    This tutorial uses the 64-bit Raspberry Pi 4, with 8 GB RAM.
    Environment Ubuntu Server 20.04.2 LTS
    Wireless router One piece
    microSD card One piece
    SD Card reader One piece
  • Step 2: Install the environment

    1. Download and install Raspberry Pi Imager 1.6.
    2. Insert the microSD card into your computer.
    3. Start Raspberry Pi Imager 1.6 and click CHOOSE OS. Select OS
    4. In the Operating System dialog box, select Other general purpose OS > Ubuntu > Ubuntu Server 20.04.2 LTS (RPi 3/4/400). Select Ubuntu Server
    5. On the page of Raspberry Pi Imager 1.6, click CHOOSE STORAGE and select your microSD card. Select SD card
    6. Click WRITE to flash the SD card with Raspberry Pi Imager. Flash
    7. Waiting for flashing completed. Flashing progress
    8. Remove the microSD card from your Mac and insert it into the Raspberry Pi.
  • Step 3: Connect Raspberry Pi to the internet

    You can connect Raspberry Pi to the internet through a wired Ethernet connection (recommended) or a Wi-Fi network.

    • Wired connection
      Use an Ethernet cable to connect Raspberry Pi to the router.
    • Wi-Fi connection
      1. Insert the flashed microSD card into your computer.
      2. Open Finder on your Mac and click Locations > system-boot.
      3. Open the network-config file with a text editor. Change the myhomewifi field to the SSID of your router and the S3kr1t field to the password of your router.
        wifis:
            wlan0:
                dhcp4: true
                optional: true
                access-points:
                myhomewifi:
                    password: "S3kr1t"
        
      4. Save the file and exit.
      5. Insert the microSD card into Raspberry Pi.
  • Step 4: Start Ubuntu Server

    1. Find your Raspberry Pi’s IP address on the local network from your router setup page. This tutorial uses 192.168.1.140 as an example.
    2. Make sure your computer and Raspberry Pi connect to the same LAN. Execute the following command to connect to Raspberry Pi.
      ssh ubuntu@192.168.1.140
      
    3. Enter the default password and then enter the new password twice to reset the password.

      Note: The default username and password of Ubuntu Server both are ubuntu.

  • Step 5: Install Home Assistant

    Install dependency

    Execute the following three commands respectively to install dependencies. The installation process will take some time.

    sudo apt-get update
    
    sudo apt-get upgrade -y
    
    sudo apt-get install -y python3 python3-dev python3-venv python3-pip libffi-dev libssl-dev libjpeg-dev zlib1g-dev autoconf build-essential libopenjp2-7 libtiff5 --fix-missing
    

    Create virtual environment

    1. Create a directory for the installation of Home Assistant.

      mkdir ~/hass
      
    2. Create and activate the virtual environment for Home Assistant.

      1. Go to the directory.
        cd ~/hass
        
      2. Create virtual environment.
        python3 -m venv .
        
      3. Activate virtual environment.
        source bin/activate
        

    Install Home Assistant

    1. Install Python package.
      python3 -m pip install wheel
      
    2. Install Home Assistant Core.
      pip3 install homeassistant
      

    Start Home Assistant

    Execute the following command to start Home Assistant.

    hass
    

    When you start Home Assistant for the first time, the system will create ~/.homeassistant directory to store configuration files and install required dependencies. This process will take some time.

    Visit http://192.168.1.140:8123 in a browser by using a device in the same LAN. If the Home Assistant homepage appears, it indicates that installation is successful.

    Note: The IP address here is only for demonstration. Use your Raspberry Pi’s IP address.

  • Step 6: Install Samba

    We use Samba to share .homeassistant directory in the LAN. You can modify the .homeassistant file directly on your computer, which will help the development of drivers.

    1. Install Samba.
      sudo apt-get install samba samba-common-bin
      
    2. Configure smb.conf file.

      Note: Yo must specify an absolute path to smb.conf, such as /home/ubuntu/.homeassistant.

      1. Edit the file.
        sudo vi /etc/samba/smb.conf
        
      2. Add the following line of code to the bottom of the configuration file.
        [pi]
        path = /home/ubuntu/.homeassistant
        writeable=Yes 
        create mask=0777 
        directory mask=0777 
        public=no 
        
      3. Save the file.
    3. Add a Samba account.

      Note: When you use the sudo smbpasswd -a command to create a Samba user, the account must be a Linux system account, such as ubuntu.

      1. Execute the following command line.
        sudo smbpasswd -a ubuntu
        
      2. Enter a password, such as a123456.
    4. Restart Samba to make the configuration effective.
      sudo systemctl restart smbd
      

    Once Samba is installed, the development environment is set up.

    Access Home Assistant folder through Samba

    1. Open Finder on your Mac.

    2. In the top-left corner of the screen, click Go > Connect to Server.

    3. In the dialog box, enter your Raspberry Pi’s IP address and click Connect.

      smb://192.168.1.140/pi
      

      Note: The IP address here is only for demonstration. Use your Raspberry Pi’s IP address.

      Connect to Raspberry Pi

    4. In the dialog box, enter the account and password of the Samba user. See the following example.

      • Name: ubuntu
      • Password: a123456
    5. Click Connect to access the Home Assistant folder shared with Raspberry Pi.
      Browse folder

Summary

You can access the Home Assistant folder through Samba and proceed with the development of drivers. For more information, see Develop Tuya-Compatible Home Assistant Drivers.
