Install the OpenHAB Ubuntu Appliance for Raspberry Pi 2

Download the OpenHAB image


Installation instructions

What you’ll need

  • A microSD card (4GB minimum, 8GB recommended)
  • A Raspberry Pi 2
  • A computer with a microSD card drive
  • A micro-USB power cable
  • A monitor with an HDMI interface
  • An HDMI cable
  • A USB keyboard

These steps will flash your OpenHAB Ubuntu Appliance to your Raspberry Pi with a Ubuntu machine, and get you logged in.

  1. Install the Raspberry Pi Imaging Tool

    Download the Imaging Tool for Ubuntu

  2. Prepare the microSD card

    Warning
    This will completely erase the microSD card.

    • Insert the microSD card into your computer
    • Run the imager and click CHOOSE OS
    • Next, choose Use Custom. Select the image you downloaded.
    • Select your microSD card and click WRITE.

    While it is preparing the disk you can go on to the next step and create your SSH keys for secure access to the appliance.

  3. Generate Secure Shell (SSH) keys

    The ‘Secure Shell’ protocol provides access to your Ubuntu Appliance and uses cryptographic keys to authenticate you to the device. You need SSH software and keys.

    Run the following command:

    ssh-keygen -t rsa
    1. This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key
    2. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase
    3. Type in a passphrase

    You now have a public and private key that you can use to authenticate.

  4. Create an Ubuntu SSO account

    Your Ubuntu Appliance will be added to your Ubuntu cloud account and use your SSH keys to identify you. Add your keys to your account at https://login.ubuntu.com/ssh-keys.

    To do so, run the following command in your terminal.

    cat ~/.ssh/id_rsa.pub

    Copy the result into the text field on the website. Click import and will have the key set up.

  5. Boot your Raspberry Pi from the microSD card

    Wait for the Raspberry Pi images to complete. Remove the microSD card from your computer and insert it into the Raspberry Pi. Attach your monitor and keyboard to the Pi, you will use them for the initial device configuration.

    If you want to use a wired network, connect your ethernet cable to the Pi before booting.

    Power up the Pi by connecting it to your USB power supply.

    Your Pi will boot, and present you with a series of configuration choices. You need to ensure that the Pi has internet access so that it can get updates and verify your SSH keys. If you need more help there is a tutorial that goes through these steps in more detail.

    Next, you will need to enter your Ubuntu cloud account email address. Your Pi will connect to your cloud account and retrieve your SSH keys.

  6. SSH in

    Your Pi will show an ssh command like:

    ssh <Ubuntu SSO user name>@<device IP address>

    Your user name is your Ubuntu SSO user name.

    Your terminal will welcome you to Ubuntu Core.

  7. That’s it

    Now that you’re in your Pi you will be able to use your OpenHAB Ubuntu Appliance image.

What you’ll need

  • A microSD card (4GB minimum, 8GB recommended)
  • A Raspberry Pi 2
  • A computer with a microSD card drive
  • A micro-USB power cable
  • A monitor with an HDMI interface
  • An HDMI cable
  • A USB keyboard

These steps will flash your OpenHAB Ubuntu Appliance to your Raspberry Pi with a Windows machine, and get you logged in.

  1. Install the Raspberry Pi Imaging Tool

    Download the Imaging Tool for Windows

  2. Prepare the microSD card

    Warning
    This will completely erase the microSD card.

    • Insert the microSD card into your computer
    • Run the imager and click CHOOSE OS
    • Next, choose Use Custom. Select the image you downloaded.
    • Select your microSD card and click WRITE.

    While it is preparing the disk you can go on to the next step and create your SSH keys for secure access to the appliance.

  3. Generate Secure Shell (SSH) keys

    After you have installed OpenSSH client you will need to generate user SSH keys to secure the connection to your Raspberry Pi.

    Launch ‘Windows PowerShell’ as an Administrator, and type:

    ssh-keygen

  4. Create an Ubuntu SSO account

    Your Ubuntu Appliance will be added to your Ubuntu cloud account and use your SSH keys to identify you. Add your keys to your account at https://login.ubuntu.com/ssh-keys.

    To do so, run the following command in your terminal.

    cat ~/.ssh/id_rsa.pub

    Copy the result into the text field on the website. Click import and will have the key set up.

  5. Boot your Raspberry Pi from the microSD card

    Next, you will need to enter your Ubuntu cloud account email address. Your Pi will connect to your cloud account and retrieve your SSH keys.

  6. SSH in

    Your Pi will show an ssh command like:

    ssh <Ubuntu SSO user name>@<device IP address>

    Your user name is your Ubuntu SSO user name.

    Your terminal will welcome you to Ubuntu Core.

  7. That’s it

    Now that you’re in your Pi you will be able to use your OpenHAB Ubuntu Appliance image.

What you’ll need

  • A microSD card (4GB minimum, 8GB recommended)
  • A Raspberry Pi 2
  • A computer with a microSD card drive
  • A micro-USB power cable
  • A monitor with an HDMI interface
  • An HDMI cable
  • A USB keyboard

These steps will flash your OpenHAB Ubuntu Appliance to your Raspberry Pi with a macOS machine, and get you logged in.

  1. Install the Raspberry Pi Imaging Tool

    Download the Imaging Tool for macOS

  2. Prepare the microSD card

    Warning
    This will completely erase the microSD card.

    • Insert the microSD card into your computer
    • Run the imager and click CHOOSE OS
    • Next, choose Use Custom. Select the image you downloaded.
    • Select your microSD card and click WRITE.

    While it is preparing the disk you can go on to the next step and create your SSH keys for secure access to the appliance.

  3. Generate Secure Shell (SSH) keys

    The ‘Secure Shell’ protocol provides access to your Ubuntu Appliance and uses cryptographic keys to authenticate you to the device. You will need SSH software and keys.

    Terminal is the terminal emulator which provides a text-based command-line interface (CLI) to the Unix shell of macOS.

    To open the macOS Terminal:

    1. In Finder, select Utilities from the Applications folder.
    2. Find Terminal in the utilities list.
    3. Enter the following command:

      ssh-keygen -t rsa

      This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key

    4. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase
    5. Type in a passphrase

    You now have a public and private key that you can use to authenticate.

    Your private key is saved to the id_rsa file in the .ssh directory and is used to verify the public key you use belongs to the same account.

  4. Create an Ubuntu SSO account

    Your Ubuntu Appliance will be added to your Ubuntu cloud account and use your SSH keys to identify you. Add your keys to your account at https://login.ubuntu.com/ssh-keys.

    To do so, run the following command in your terminal.

    cat ~/.ssh/id_rsa.pub

    Copy the result into the text field on the website. Click import and will have the key set up.

    Your user name is your Ubuntu SSO user name.

    Your terminal will welcome you to Ubuntu Core.

  7. That’s it

    Now that you’re in your Pi you will be able to use your OpenHAB Ubuntu Appliance image.

Start using your OpenHAB Ubuntu Appliance

When you start openHAB for the first time, it only starts the dashboard. So let's have a look at it: open a browser and browse to your openHAB dashboard:
