Nuki Smart Lock Pro (4th Generation)

The Nuki Smart Lock Pro (4th Generation) from Nuki uses Matter over Thread to connect to your smart home. Thread is a low-power mesh network built for devices like a Lock. Devices pass messages to each other, so the mesh gets stronger and reaches further with every router you add.

In a Thread network, the Nuki Smart Lock Pro (4th Generation) works as a End Device (MTD).

Border Router (TBR)

A Thread Border Router connects your Thread devices to your home network, so no extra hub is needed.

Router (FTD)

A Thread Router stays powered on and relays messages for other devices, extending the range of your network.

End Device (MTD)

A Thread End Device talks to nearby routers and does not relay messages, which saves power and battery life.

Every Thread router you add makes your mesh stronger and extends its range. See all Thread devices →

Matter over Wi-Fi

The Nuki Smart Lock Pro (4th Generation) from Nuki 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 →

Does the Nuki Smart Lock Pro (4th Generation) work without internet?

Do I need the Nuki app to use the Nuki Smart Lock Pro (4th Generation)?

No. Any Matter hub can set up and control the Nuki Smart Lock Pro (4th Generation) without the Nuki app. Some advanced features may not be part of Matter yet, so settings like firmware updates or special modes can still require the Nuki app.

Open your smart home app, choose to add a device and scan the Matter QR code on the Nuki Smart Lock Pro (4th Generation) or its packaging. You can also type in the 11-digit Matter code instead. The app guides you through the rest. Keep the code safe, you need it again after a reset.
