Smart Home Security System Guide

action.devices.types.SECURITYSYSTEM - Security systems can be armed and disarmed. They can be armed at multiple security levels (for example, home and away) and they can report information about certain sensors, such as a sensor that detects motion or an open window.

This type indicates that the device gets the Security System icon and some related synonyms and aliases.

Device capabilities

Refer to the corresponding trait documentation for implementation details, such as attributes and states that your service should support, and how to build EXECUTE and QUERY responses.

These traits are recommended, if applicable to your device. However, you are free to mix and match from all available traits to best match your existing product functionality.

Example device: Simple security system

This section contains example intent payloads representing a common "Security System" based on the device type and traits above. If you add or remove traits in your implementation, modify your responses accordingly to reflect those changes.

Device ERRORS

See the full list of errors and exceptions.

Report arming exceptions

When attempting to arm or disarm the system, you can provide additional context via exceptions codes that you report through the StatusReport trait. Exceptions can be reported as blocking or non-blocking.

  • Non-blocking exceptions reported with a "SUCCESS" status indicate that the exception did not prevent arming or disarming.
  • Blocking exceptions reported with an "EXCEPTIONS" status indicate that arming or disarming was stopped because of these exceptions.

Exception codes that are commonly associated with security systems include:

  • doorOpen: A door is open.
  • windowOpen: A window is open.
  • isOpen: A sensor detects something is open (but doesn’t know if it’s a door or window).

Example: Non-blocking exception

This example shows a non-blocking exception where the security system is armed even though a window is reported as open.

User Set the security system to high security.
Google Assistant Ok, the front window is open. Arming security system to high security.

Arming with two-factor authentication

If your arming flow requires users to input a PIN through a two-factor authentication dialog, you must acknowledge whether they would like to continue arming the system when there are active exceptions (for example, when a window or door is open).

This scenario may require both a PIN or passphrase entry, followed by an acknowledgment.

Example: Acknowledgement challenge

This example shows a user attempting to arm the security system, but a front door is detected as open. The user acknowledges that the security system should be armed even though the front door is open.

User Arm the security system.
Google Assistant The front door is open. Are you sure you want to arm the security system?
User Yes.
Google Assistant Ok, arming the security system.

In the first turn, you should respond with an ackNeeded challenge.

Example: PIN and acknowledgement challenge

This example shows a user attempting to arm the security system requiring PIN input. The system detects that the front and back windows are open and asks the user to acknowledge that arming should proceed.

User Arm to away.
Google Assistant What's your PIN?
User 1234.
Google Assistant It looks like the front window and back window are open. Are you sure you want to continue arming the security system to away?
User Yes.
Google Assistant Okay, arming the security system to away

In the first turn, you should respond with a standard pinNeeded challenge.

      "challengeNeeded": {
        "type": "pinNeeded"
      }
