"Brillo extends the Android platform to all your connected devices, so they are easy to set up and work seamlessly with each other and your smartphone."
Phone to device to cloud
Weave provides seamless and secure communication between devices both locally and through the cloud. It’s integrated into the Google mobile platform, so support is built-in to Android and easily available for iOS.
Interoperate across manufacturers
The Weave program will drive interoperability and quality through a certification program that device makers must adhere to. As part of this program, Weave provides a core set of schemas that will enable apps and devices to seamlessly interact with each other.
Compatible with Nest
Nest and Nest ecosystem devices will also use Weave, so they can easily and securely interoperate with devices from other manufacturers."
