Google Developer Home Script Looping Until Door Is Closed

Imagine a world where your smart home automatically verifies if the door is closed before you settle in for the night. Google Developer Home lets you create such automations using scripts! Here's how to write a script that loops until your door confirms it's closed, providing an extra layer of security with this guide 
Google Developer Home Script Looping Until Door Is Closed. 

Understanding the Setup: google developer home script looping until door is closed

Before diving into the code, ensure you have the following:

1.      Google Assistant with a compatible smart speaker: This is the hub that will run your script.

2.      Smart door sensor: This sensor will detect whether your door is open or closed. Many smart home brands offer compatible door sensors.

The Script's Superpower: Looping Until Secured

The magic of this script lies in its ability to continuously check the door's status until it's closed. 
Here's a breakdown of the code:


// This function checks the door sensor status
function isDoorClosed() {
  const doorSensor = AssistantDevices.getSensor("Your Door Sensor Name");  // Replace with your sensor's name
  return doorSensor.getIsOpen();

// This loop keeps checking until the door is closed
while (isDoorClosed()) {
  // Display a message (optional)
  console.log("Door is still open. Please close it to continue.");
  // You can also add an audio cue here using Assistant sdk methods
  // Wait for a short interval before checking again
  Utilities.sleep(5000);  // Adjust the waiting time in milliseconds (5 seconds in this example)

// Door is closed! (Optional)
console.log("Door is closed. Have a safe night!");

Use this code 

Breaking Down the Code: Google developer home script looping until door is closed

1.      The isDoorClosed function retrieves the door sensor's status using the AssistantDevices library. Replace "Your Door Sensor Name" with the actual name assigned to your door sensor in the Google Home app.

2.      The while loop continuously calls the isDoorClosed function. As long as the function returns true (meaning the door is open), the loop continues.

3.      Inside the loop, you can optionally display a message on your smart speaker or play an audio cue using the Assistant SDK methods.

4.      The Utilities.sleep function pauses the script for a brief period (5 seconds in this example) before checking the door sensor again. Adjust this time as needed.

5.      Once the loop exits (because the door is closed), an optional message can be displayed to confirm.

Putting it All Together:

1.      Copy and paste the script into your Google Apps Script project.

2.      Replace "Your Door Sensor Name" with the actual name of your door sensor.

3.      Save the script and give it a descriptive name.

4.      Trigger the script using your preferred method voice command, routine, or schedule.


  1. This is a basic example. You can customize it further by adding functionalities like sending phone notifications if the door remains open for an extended period.
  2. Always refer to Google's Assistant SDK documentation for the latest libraries and methods.
By implementing this script, you can leverage the power of Google Developer Home to create a more secure and automated smart home experience. So, code your way to peace of mind and enjoy the comfort of knowing your doors are closed tight!
