Requirements for Specific Device Types

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

To receive Works with Alexa (WWA) certification, your device must meet the following requirements for your device type. These requirements apply to products that connect to Alexa with an Alexa smart home skill and the Alexa Connect Kit (ACK), and products that have Alexa built-in. Hubs that integrate other smart home devices with Alexa are also eligible for WWA certification.

For the complete list of smart home interfaces, see List of Alexa Interfaces and Supported Languages.

General device requirements

Your device must implement the capability interfaces for the features that your product supports. To be eligible for certification, your device must support the required interfaces specified for your device category. Some device types have no required capability interfaces. For details, see the required capability interfaces for your device category.

In addition, your device must meet the following requirements:

All devices must support device discovery and state reporting. For details, see Alexa.Discovery and Understand State Reporting.
You must include manufacturer and model in the additionalAttributes object in the discovery response. For Alexa to identify unique devices, include as many other attributes as you can.
To let Alexa know the health of your device, implement EndpointHealth. As a best practice, support as many EndpointHealth properties as you can.

Requirements for hubs

To receive WWA certification, a hub must connect smart home devices to Alexa.

Required capability interfaces

Review the mandatory interfaces for your device category. If your device connects to Alexa with Matter, make sure that your product supports the required Matter clusters for your device category.
