Matter overview

Matter (formerly Project Connected Home over IP or Project CHIP) is an open-source application layer that aims at creating a unified communication standard across smart home devices, mobile applications, and cloud services. It supports a wide range of existing technologies, including Wi-Fi, Thread, and Bluetooth® LE, and uses IPv6-based transport protocols like TCP and UDP to ensure connectivity between different kinds of networks.
