Eufy Smart FamiLock E40

The Eufy Smart FamiLock E40 from Eufy connects to your smart home over Wi-Fi. It joins your existing network directly, without a Thread Border Router or extra hub, and your Matter controller reaches it through your home router.

Wi-Fi Band

Most Matter Wi-Fi devices only connect on 2.4 GHz. If your router combines 2.4 and 5 GHz under one SSID, split them to avoid issues.

Same Network

Your phone, your controller and the device must be on the same network. Guest networks and separate VLANs can block Matter.

Power Use

Wi-Fi uses more power than Thread, so most Matter over Wi-Fi devices run on mains power instead of batteries.

Every Matter device needs a Matter controller, like a smart hub, display or speaker. See all Matter hubs →
