Smart Home Doorbell Guide

action.devices.types.DOORBELL - Doorbells can let people know someone is at the door. This device can send notifications and stream video if it has the corresponding capability.

This type indicates that the device gets the Doorbell 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.

Quality requirements

  • Latency: must be less than or equal to 2000ms.
  • Reliability: must be more than or equal to 97%.

Example device: Simple doorbell

This section contains example intent payloads representing a common "Doorbell" 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.
