Connectivity Standards Alliance
CSA
Matter device spec and certification requirements are CSA — the index spans Matter core, clusters, and device types.
What It Is

Matter is the end-state for smart home interoperability. Any connected home product launched today needs Matter support. Understanding commissioning, fabric topology, and the data model is essential for IoT product developers.
Zigbee is installed in hundreds of millions of devices. Smart lighting (Hue, IKEA Trådfri), home hubs (SmartThings, Home Assistant), and building automation all use it. Understanding ZCL clusters and coordinator setup is required for integrations.
Thread is the networking layer under Matter — when you see Matter over Thread, Thread is doing the mesh networking. Understanding the border router, DTLS commissioning, and leader/router/end-device roles is required for Matter deployments.
Z-Wave is strong in smart locks, sensors, and dimmers — especially from legacy vendors. Integration with Home Assistant, SmartThings, or Z-Wave JS requires understanding mesh inclusion and command classes.
