Before Starting the setup

For Google Assistant

1. Create a project in the Google's Action Console.
2. Download credentials--->.json file (refer to this doc for creating credentials https://developers.google.com/assistant/sdk/develop/python/config-dev-project-and-account)

For Amazon Alexa

1. Create a security profile for alexa-avs-sample-app if you already don't have one.
   https://github.com/alexa/avs-device-sdk/wiki/Create-Security-Profile

2. Download the "config.json" file.

Setup Amazon Alexa, Google Assistant or Both

1. Clone the git using:

git clone https://github.com/shivasiddharth/Assistants-Pi  

DO NOT RENAME THE CREDENTIALS FILEs
Place the Alexa config.json in file in the /home/pi/Assistants-Pi/Alexa directory.
Place the Google client_secret.....json file in the /home/pi/ directory.

2. Make the installers executable using:

sudo chmod +x /home/pi/Assistants-Pi/scripts/prep-system.sh    
sudo chmod +x /home/pi/Assistants-Pi/scripts/audio-test.sh   
sudo chmod +x /home/pi/Assistants-Pi/scripts/installer.sh  

3. Prepare the system for installing assistants by updating, upgrading and setting up audio using:

sudo /home/pi/Assistants-Pi/scripts/prep-system.sh

4. Restart the Pi using:

sudo reboot

5. Make sure that contents of asoundrc match the contents of asound.conf
   Open a terminal and type:

sudo nano /etc/asound.conf

Open a second terminal and type:

sudo nano ~/.asoundrc

If the contents of .asoundrc are not same as asound.conf, copy the contents from asound.conf to .asoundrc, save using ctrl+x and y

6. Bonus Script - Test the audio setup using the following code (optional). Dont panic if the test does not go through successfully, proceed with the installation:

sudo /home/pi/Assistants-Pi/scripts/audio-test.sh  

7. Restart the Pi using:

sudo reboot

8. Install the assistant/assistants using the following. This is an interactive script, so just follow the onscreen instructions:

sudo /home/pi/Assistants-Pi/scripts/installer.sh  

9. After verification of the assistants, to make them auto start on boot:

Open a terminal and run the following commands:

sudo chmod +x /home/pi/Assistants-Pi/scripts/service-installer.sh
sudo /home/pi/Assistants-Pi/scripts/service-installer.sh  

For Alexa:

sudo systemctl enable alexa.service  

For Google Assistant:

sudo systemctl enable google-assistant.service  

10. Authorize Alexa before restarting

sudo /home/pi/Assistants-Pi/Alexa/startsample.sh  

Manually Start The Alexa Assistant

Double click start.sh file in the /home/pi/Assistants-Pi/Alexa folder and choose to "Execute in the Terminal".

Manually Start The Google Assistant

Open a terminal and execute the following:

/home/pi/env/bin/python -u /home/pi/Assistants-Pi/Google-Assistant/src/main.py --project_id 'replace this with the project id '--device_model_id 'replace this with the model id'

If you have issues with the Assistants strating on boot, you may have to setup PulseAudio as a system wide service. For further details refer this git https://github.com/shivasiddharth/PulseAudio-System-Wide
