• Click the download icon: ⬇ (at the far right of screen) for the client ID to download the client secret JSON file. (you may need to scroll the page to the right to see the icon) Save the file.

Prepare Raspberry Pi

Install LibreELEC

Boot the Pi using LibreELEC from PINN (PINN Is Not NOOBS):

https://sourceforge.net/projects/pinn/

or using the LibreELEC installer:

https://libreelec.tv/downloads/

Enable SSH

• Kodi main menu -> Add-ons -> LibreELEC Configuration -> Services -> Enable SSH

Enable Audio Output

• Connect using SSH and edit the boot config:

mount -o remount,rw /flash
vi /flash/config.txt

• Add this parameter:

dtparam=audio=on

• Reboot

Install Add-ons:

Install the Docker add-on :

• Kodi main menu -> Add-ons -> Install from repository

• LibreELEC Add-ons -> Services -> Docker

Install the Portainer add-on:

• LibreELEC Add-ons -> Add-on Repository -> LinuxServer.io's Docker Add-ons

• Kodi main menu -> Add-ons -> Install from repository
• LinuxServer.io's Docker Add-ons -> Services -> Portainer

Install and Configure Google Assistant

Access Portainer at: http://192.168.1.12:9000 (replace the IP with the address of your Raspberry Pi)

Deploy Container

• Containers -> Add container
  • Container name: GoogleAssistant
  • Image configuration Name: obstruse/googleassistant
  • Disable Access control
  • Console: Interactive & TTY
  • Restart policy: Unless stopped
  • Runtime & Resources: add device: /dev/snd
• Click Deploy the container

Install Credentials

• Click on the container name and select ">_ Console"
• click Connect
• In the console window, enter:

/root/installCred.sh

• Paste the contents of the client_secret.json file saved at the beginning of the proceedure
• Copy the URL displayed in the console window and paste it in a browser
• Copy and paste the returned access code into the console window
• Restart the container

Audio Output

Volume

The output audio level is set to 60% after installation. To increase the volume, say the following:

"Hey Google, set volume to maximum"

Output Device

The Raspberry Pi automatically selects either HDMI or speaker jack for audio output, depending on what's available at boot time. If both are available, it defaults to HDMI. To force it to always use the speaker jack:

• Connect using SSH and edit/create autostart.sh:

vi /storage/.config/autostart.sh

• Add this line:

amixer cset numid=3 1

• Reboot

Google Assistant will use the speaker jack for output, and Kodi will continue to use HDMI
