MMM-GoogleAssistant

MMM-GoogleAssistant is a customizable hotword detection module to activate/notify other MagicMirror modules. This is a pre-trained model that can activate an embedded Google Assistant that requires OAuth Keys. The Porcupine Wake Word Engine is open-source and executes ONLY locally.

Google Assistant Keys + Setup

1. Create a Google Project on Actions Console & click on device registration:

ENABLE THE FOLLOWING APIS on your Google Cloud Project in the Google Cloud Console:

• Cloud Pub/Sub API
• Google Assistant API
• Cloud Speech-to-Text API

2. Register a model & download the client_secret.json

3. Run Jarvis.js to test your configuration and say "Jarvis"

4. The system will open a local browser and require you to login with your Google Account.

If you would like to setup facial recognition on another device, highly recommended setup instructions here: https://github.com/jeffmur/Smart-Mirror

Now your tokens.json will be automatically generated and access to the Embedded Google Assistant API.
