Good to know

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.
Remote control and automations require an Apple home hub (HomePod mini, HomePod, or Apple TV).
Thread-enabled Matter accessories require a Thread-enabled home hub such as HomePod mini or Apple TV 4K (3rd generation) Wi-Fi + Ethernet.
