Alexa.DoorbellEventSource Interface

Implement the Alexa.DoorbellEventSource interface in your Alexa skill for devices that raise doorbell events. The customer selects which of their Echo devices respond to doorbell events. Alexa uses doorbell events for announcements, mobile notifications, routines, and other use cases. For more details about security skills, see Smart Home Security Overview.

When a doorbell event occurs, Alexa plays the doorbell announcement on the selected Echo devices. If the customer selected an Echo device without a screen, the Echo device plays the doorbell announcement. If the customer selected an Echo Show device and the doorbell implements the Alexa.RTCSessionController interface, the Echo Show device plays the doorbell announcement and automatically displays a live feed from the doorbell video camera when the doorbell event occurs.

For the list of languages that the DoorbellEventSource interface supports, see List of Alexa Interfaces and Supported Languages.
