Good to know

Google hubs do not include Zigbee radios; Zigbee devices need their own bridge.
Matter-over-Thread devices need a Google Thread border router: Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro, Google TV Streamer (4K) or Google Home Speaker (2026).
Matter runs over Wi-Fi or Thread. Matter-over-Thread accessories also need a Thread border router somewhere in the home (see radio:thread-border-router); a Wi-Fi-only controller is not enough on its own.
Each ecosystem supports a subset of Matter device types, so check that your controller supports the accessory's type (e.g., lock, thermostat, sensor).
Some products reach Matter through a bridge (e.g., Philips Hue Bridge, Aqara Hub M3) rather than speaking Matter themselves.
Matter-over-Wi-Fi accessories typically need a 2.4 GHz Wi-Fi network.
