Matter Device Library Specification: what it is, and every device type with its certified models

Every device type with certified models

The device types certified product models state on the CSA ledger (November 2026), most models first. "On Matter 1.5 or later" counts models whose highest certificate version is 1.5 or newer. 837 models state no device type yet and are in no row. Each type links to its group's page, with the newest models and the companies.

What the Device Library Specification covers

The CSA's CSA: Matter Device Library Specification, version 1.4.2 (dated July 16, 2025, read November 1, 2026) groups the device types into chapters: “Lighting Device Types”, “Smart Plugs/Outlets and other Actuators”, “Switches and Controls Device Types”, “Sensor Device Types”, “Entry Control Device Types”, “HVAC Device Types”, “Media Device Types”, “Robotic Device Types”, “Appliances Device Types”, “Energy Device Types” and “Network Infrastructure Device Types”. Google's Matter primer explains what a device type is: "A Device Type is a collection of mandatory and optional Clusters that define the top-level attributes of a physical Device, such as Dimmable Light, Door Lock, or Video Player." (Google Home Developers: Matter primer, Device Data Model, read November 10, 2026).

Each Matter release is published as four specifications. For the newest, the CSA's specifications page (re-read November 12, 2026) lists “Matter 1.6.1 Core Specification”, “Matter 1.6.1 Application Clusters Specification”, “Matter 1.6.1 Device Type Library Specification” and “Matter 1.6.1 Standard Name Space Specification”. The documents are requested through that page. Which release added which device types: Matter versions explained; the latest version and its certified devices: Matter versions.
