Note:

Due to the 20th Dec update to Google Assistant SDK, the installation process has remarkably changed. Please Read through this document carefully
Refer to this video https://youtu.be/vprJBDDYE8Q for critical steps in Google Assistant installation

The Google Assistant Component used in this project is the GassistPi project. So for 'Preliminary Setups for the customizations and respective How-Tos' check this out

Setup Amazon Alexa, Google Assistant or Both

---

1. Clone the git using:

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

2. Make the installers executable using:

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

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

sudo /home/pi/Assistants-Pi/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. Test the audio setup using:

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

9. After verification of the assistants, to make them auto start on boot:
   Pi 3 and Pi2 users, open the gassistpi-ok-google.service in the /home/pi/Assistants-Pi/systemd folder and add your project-id and model-id in the indicated points.
   Pi Zero users, open the gassistpi-push-button.service in the /home/pi/Assistants-Pi/systemd folder and add your project-id and model-id in the indicated points.
   After that, open a terminal and run the following commands:

sudo chmod +x /home/pi/Assistants-Pi/scripts/service-installer.sh
sudo chmod +x /home/pi/Assistants-Pi/scripts/clientstart.sh  
sudo chmod +x /home/pi/Assistants-Pi/scripts/companionstart.sh  
sudo chmod +x /home/pi/Assistants-Pi/scripts/wakeword.sh  
sudo /home/pi/Assistants-Pi/scripts/service-installer.sh  
sudo systemctl enable companionapp.service
sudo systemctl enable client.service
sudo systemctl enable wakeword.service
sudo systemctl enable stopbutton.service

#If using Pi 2B or Pi 3B

sudo systemctl enable gassistpi-ok-google.service  

#If using Pi zero

sudo systemctl enable gassistpi-push-button.service  

Manually Start The Google Assistant

At any point of time, if you wish to manually start the assistant:

Ok-Google Hotword/Pi3/Pi2/Armv7 users
Open a terminal and execute the following:

/home/pi/env/bin/python -u /home/pi/GassistPi/src/main.py --device_model_id 'replace this with the model id'

Pushbutton/Pi Zero/Pi B+ and other users
Open a terminal and execute the following:

/home/pi/env/bin/python -u /home/pi/GassistPi/src/pushbutton.py --project-id 'replace this with your project id'  --device-model-id 'replace this with the model id'
