You can connect your smart home device to Alexa with the Thread wireless connectivity protocol. Thread is an IPv6 wireless-mesh-networking technology designed for security, reliability, and scalability. As a low-power technology, Thread can extend the lifetime of battery-powered smart home devices. The IP-based open-standard mesh network broadens network coverage to keep smart home devices working even if one device goes offline. For more details about Thread, see The Thread Group. Thread-enabled Amazon Echo devices act as Thread Border Routers to provision and secure Thread networks. With the customer’s permission, your smart home add-on can access and select the most appropriate wireless Personal Area Network (PAN) to connect your Matter over Thread (MoT) device seamlessly. When a customer enables your add-on, they can share their network credentials with Alexa and your add-on. This eliminates the step to enter network credentials manually for each device that they add to the network.

​
Compatible Amazon Echo and eero devices

Thread-enabled Amazon Echo and eero devices have built-in Thread Border Routers and support Thread version 1.1 or 1.3 defined by the Thread Group. For details about the Thread protocol, see the Thread Specification. The following Amazon Echo and eero devices have Thread Border Routers built-in.

​
Add permissions for Thread network credentials

You can use the Credential Locker REST API in your smart home add-on to get customer Thread network credentials or create a new customer Thread network for Matter device setup. You can use these credentials to commission Matter devices to the customer’s wireless PAN. To use this API, you must add the add-on permission for Thread network credentials with customer consent. To enable this permission in the Alexa developer console, complete the following steps. To add permission to read Thread network credentials in the developer console
  1. Sign in to the Alexa developer console.
  2. On the Skills tab, under SKILL NAME, find your add-on.
  3. Under ACTIONS, expand the dropdown list in your add-on’s row, and then select Edit.
  4. In the left pane, select PERMISSIONS.
  5. To enable permission to read and write Thread network credentials, toggle Access network credentials.
You can also update the skill manifest by using the Alexa Skills Kit Command Line Interface. To enable the thread network permission, include the credential_locker:thread_networks:readwrite permission in the permissions field of your skill manifest. After you update and save your manifest file, use the Alexa Skills Kit Command Line Interface to deploy the changed manifest.

Obtain the Works with Alexa badge

Works with Alexa (WWA) is a certification program that establishes your product’s high-quality compatibility with Alexa. This certification makes sure that your customers have a better smart home experience. For details about the WWA program, see Works with Alexa Overview. After you have thoroughly tested your Thread-enabled device with the Echo, you can submit your product for WWA certification. To register a Thread device for WWA, make sure to select Thread for the communication protocol that your device uses to connect to Alexa. In addition, make sure that your MoT device meets the WWA requirements for Matter. For details, see Apply for Works with Alexa Certification.
