It's not too often that there's an international launch event for an interoperability standard with a nearly 900-page spec manual. But there are big hopes pinned to Matter, an industry-wide effort to make smart home devices easier to shop for and set up without compatibility concerns.

Companies brought their Matter-ready devices to Amsterdam overnight for the Connectivity Standards Alliance's (CSA) Matter Launch Event. The CSA states that 190 devices have been certified for Matter since the standard was finalized in early October. Those devices include motion blinds, smart plugs, HVAC controls, door locks, lighting, hubs and gateways, and certain kinds of sensors. More device categories, including vacuums, cameras, and large appliances, are due next.
