This sample contains a fully functioning example of a Smart Home provider cloud service designed to work with Actions on Google. This can be used with a Actions Console project to create an Action interface to your IoT devices. This sample includes everything you need to get started, including a mocked user authentication service with sample users and a user web portal to demonstrate the user experience when controlling their lights with your action.
An example of a Smart Home IoT cloud engine is stored in
smart-home-provider/cloud. This consists of both the main
smart-home-provider-cloud.js main web service, as well as the web portal used
to interact with virtual devices in frontend/. smart-home-provider-cloud.js
is the entry point to the Node.js Express app that runs the IoT cloud service,
and handles authentication, and ultimately handles requests from the Google
Assistant.
The primary AoG intent handlers are stored in
smart-home-provider/smart-home-app.js. Here, you can find listeners for POST
requests similar to the one your app will receive from the Google Assistant
when SYNCing, QUERYing, or EXECuting smart home device control with your cloud.
The path for requests to this app is '/ha'.
This sample also includes a mock-assistant-platform module that you can use to
locally test your Smart Home app with mocked requests for the SYNC, QUERY, and
EXEC intents that you will receive from the Google Assistant. See below for
instructions on how to use. It is hard coded to use the account under username
'rick' given in smart-home-provider/cloud/datastore.js. However you swap the
appropriate Bearer token in the makeReq method of the mock-assistant-platform.
See the developer guide and release notes at https://developers.google.com/actions/ for more details.
-
Navigate to the Actions Console and click Add/Import Project.
-
Create a new project or import an existing Google Cloud project.
-
Navigate to the Google Cloud Console API Manager for your project.
-
Click Credentials
-
Click 'Create credentials'
-
Click 'API key'
-
Copy the API key shown and insert it in
smart-home-provider/cloud/config-provider.js -
Set up the web portal
cd smart-home-provider/frontend npm install -g bower bower install cd .. -
Run cloud/smart-home-provider-cloud.js, either locally or hosted
-
If running locally
cd cloud/ npm install node smart-home-provider-cloud.js isLocal -
If running in a hosted env,
node smart-home-provider-cloud.js smart-home-pub="https://your_domain.com"
-
-
In the resulting output, note the config data. In particular the client ID and client Secret.
-
In a browser, open the ngrok URL shown.
-
Log in with one of the sample user accounts, for instance
user: rick password: oldman -
This is a web portal to your Smart Home devices. Configure the smart lights shown as you please. Click the cloud icon shown above at least one of them to enable it for cloud control.
-
Return to the Actions Console project. Click 'Use Actions SDK'.
-
Update the Action Package (action.json) with the URL where your project is hosted (don't forget to include /ha).
-
Use the gActions CLI to run the command given with the 'action.json' file as your Action Package.
-
Click Okay.
-
Click ADD under App information.
-
Give your App some information like an invocation name, some description, and some policy and contact info.
-
Click Save.
-
Click Add under Account Linking.
-
Select 'Authorization Code' for Grant Type.
-
Under Client Information, enter the client ID and secret from earlier.
-
The Authorization URL is the hosted URL of your app with '/oauth' as the path, e.g. https://xyz123.ngrok.io/oauth
-
The Token URL is the hosted URL of your app with '/token' as the path, e.g. https://xyz123.ngrok.io/token
-
Enter any remaining necessary information you might need for authentication your app. Then Save.
-
On a device with the Google Assistant logged into the same account used to create the project in the Actions Console, enter your Assistant settings.
-
Click Home Control.
-
Click the '+' sign to add a device.
-
Find your app in the list of providers.
-
Log in to your service.
-
Start using the Google Assistant or Simulator in the Actions Console to control your devices. Try saying 'turn my lights on'.
âšī¸ Assistant will only provide you control over items that are registered, so if you visit your front end https://xyz123.ngrok.io and click the cloud icon to enable a device you will need to unlink and then re-link your account to see the new or removed devices.
-
Set up the web portal
cd smart-home-provider/frontend npm install -g bower bower install cd .. -
Run cloud/smart-home-provider-cloud.js, either locally or hosted
-
If running locally
cd cloud/ npm install node smart-home-provider-cloud.js isLocal -
If running in a hosted env,
node smart-home-provider-cloud.js smart-home-pub="https://your_domain.com"
-
-
In the resulting output, note the config data. In particular the client ID and client Secret.
-
In a browser, open the ngrok URL shown.
-
Log in with one of the sample user accounts, for instance
user: rick password: oldman -
This is a web portal to your Smart Home devices. Configure the smart lights shown as you please. Click the cloud icon shown above at least one of them to enable it for cloud control.
-
Use the mock-assistant platform to send requests to your Smart Home app.
cd mock-assistant-platform node platform help node platform url="https://<NGROK_DOMAIN>.ngrok.io/ha" sync node platform url="https://<NGROK_DOMAIN>.ngrok.io/ha" query node platform url="https://<NGROK_DOMAIN>.ngrok.io/ha" ex
For more detailed information on deployment, see the documentation.
Your app will need to handle these 3 basic requests from the Google Assistant.
