Get Started with Device Templates

Note: Sign in to the developer console to build or publish your skill.

You can connect virtually any type of device to Alexa by using the Smart Home API. You describe your device endpoints and capabilities by using the standard discovery mechanism described in About Alexa Discovery. In your discovery response, you identify the smart home interfaces that each device supports.

To help you get started, review the device templates to find the ones that match your device type. Each template recommends a set of smart home interfaces to implement for the device type. You can modify these recommendations by adding or removing interfaces to suit the needs of your specific device. Every template includes the required top-level Alexa interface and recommends that you implement the Alexa.EndpointHealth interface to report the health of your device to Alexa. Also, each template recommends a display category. The display category determines the icon and placement of your device in the Alexa app.

For more details about Smart Home skills, see Understand the Smart Home Skills. For more details about required interfaces for Works with Alexa (WWA) certification, see Requirements for Specific Device Types.
