GOOGLE HOME FOR LOXONE

This project allow you to control your Loxone Server from your Google Home.

Requirements

To use this plugin, you have to create your own SmartHome project in google : https://developers.google.com/assistant/smarthome/develop/create

Set up an OAuth 2.0 server

We suggest to use the free oauth 2.0 server : OAuth0

1. Create an account or login
2. Create a new application (Eg : Google Home)
3. In Allowed Callback URLs section, add https://oauth-redirect.googleusercontent.com/r/YOUR_GOOGLE_PROJECTNAME

### Create an Actions on Google developer project

1. Use your Oauth0 App ClientId et ClientSecret, created before, in the Account Linking Section
2. In the Fulfillment section, use the google-home-loxone url (Eg : http://YOUR_IP:3000/smarthome). It must be accessible from the cloud.

Request State Config

The Report State feature allows a cloud integration to proactively provide the current state of devices to the Home Graph without a QUERY request. This is done securely through JWT (JSON web tokens).

1. Navigate to the Google Cloud Console API Manager for your project id.
2. Enable the HomeGraph API. This will be used to request a new sync and to report the state back to the HomeGraph.
3. Click Credentials
4. Click 'Create credentials'
5. Click 'Service Account'
6. Create a new service account by folling steps (without specific role)
7. Edit the service account and add a new JSON key
8. Download the key and save it in your home directory ~/.google-home-loxone/jwt.json
