Matter thermostats

MatterCatalog lists 21 Matter thermostats sold in the US; 18 have a CSA (Connectivity Standards Alliance) certificate on file, and each product page shows its certificate ID or says that none is verified. 16 records name Wi-Fi as the Matter network, which needs only your platform’s Matter controller; 2 name Thread, which also needs a Thread border router. Our top CSA-certified picks are the Meross MTS300MA (24 V HVAC, configure the equipment first), the Nest Learning Thermostat (4th gen) (24 V HVAC, learning schedules and a room sensor) and the Nest Thermostat (2020) (24 V HVAC, scheduled temperature control).
