A secure and reliable communications backbone for the connected home.

OpenWeave

OpenWeave is an open-source implementation of the Weave network application layer, the secure, reliable communications backbone for Nest products. It is a versatile and lightweight solution for low-powered devices.

At Nest, we believe the core technologies that underpin connected home products need to be open and accessible. Alignment around common fundamentals will help products securely and seamlessly communicate with one another.

Why use OpenWeave?

OpenWeave's features were driven by requirements Nest identified while building their ecosystem of products. Weave's encryption protocols are designed to fit the processor and memory constraints of today's IoT devices.

With OpenWeave, you can use the same best-in-class communications technology that the Nest family of products does.
  • lock

    Secure communications

    Weave security is independent of the underlying network. Every interaction between products, apps, and cloud services is secure.
  • verified_user

    Fast and reliable

    Weave products can talk directly to each other without relying on the cloud. Even if the internet goes down, or there is a power outage, Weave products can continue to work together.
  • wifi

    Easy to connect

    Weave is as easy as scanning a QR code. It securely adds the new device to the device-to-device network. Then those devices help the new one connect to the internet.

Features

Not only does OpenWeave implement Weave, but it includes a variety of features and tools that make building, deploying, and testing a Home Area Network (HAN) easy.

Protocols and Profiles

OpenWeave is more than just trait management. It includes multiple protocols such as the Weave Web API for device-to-cloud interactions and Weave Reliable Messaging for device-to-device communications. Profiles such as Echo, Heartbeat, and Time Sync ensure the stability of the Weave fabric.

Test Scripts

Use the included suite of unit test scripts to automate testing of Weave functionality in your simulated IoT deployment. Or build your own using the Java, Cocoa, or Python bindings.

Better with OpenThread

OpenThread released by Nest is an open-source implementation of the Thread networking protocol. OpenWeave can run on top of OpenThread, taking advantage of Thread's reliable mesh networking and security. OpenWeave + OpenThread is a production-scale IoT solution that's second to none.
