An overview of the process for certifying a Cloud-to-cloud integration.

Overview

Cloud is our most flexible integration, supporting more than 80 device types, including those devices not currently supported by Matter.
Cloud-to-cloud enables control at home and remotely, even for new smart home users without a Matter controller like a Nest speaker, display or Wi-Fi.
For developers building Matter devices, cloud-to-cloud can serve as a seamless fallback for users with or without a local controller.
