Nuki Smart Lock Ultra (EU): what it works with

Nuki · model Smart Lock Ultra · For Europe

• Matter Yes, over Thread
• Apple Home Via Matter
• Google Home Via Matter
• Amazon Alexa Via Matter
• SmartThings Via Matter
• Home Assistant Via Matter

Thread-based Matter is how the Nuki Smart Lock Ultra reaches Apple Home, Google Home, Alexa, SmartThings and Home Assistant, and the lock is CSA-certified. Wi-Fi is built in, so remote access needs no Nuki Bridge. It's a cylinder lock: the 58 mm Universal Cylinder replaces yours. The battery is built in and recharges in about 2 hours, and there's no keypad on the lock itself.

• Radio: Nuki's Ultra datasheet lists Bluetooth Low Energy, 2.4 GHz Wi-Fi and Thread (IEEE 802.15.4). The CSA listing names Thread and Bluetooth as Matter transports.
• Hub: Built-in Wi-Fi gives remote access without a Nuki Bridge. Matter control needs a Thread border router.
• Local control: No Nuki source describes offline or local-only control explicitly.
• Fit: Ships with an integrated Universal Cylinder (58 mm) that replaces your existing cylinder; Nuki's comparison table says a cylinder change is required.
• Keypad: No keypad on the lock. Nuki lists Keypad, Keypad 2 and Keypad 2 Pro as separate accessories.
• Power: Recharges in about 2 hours, on or off the door; Nuki warns when it drops below 20%.

Before you buy

• Matter needs a Thread border router; Nuki says a Wi-Fi-only Matter hub will not work.
• Installation means swapping your existing cylinder for the integrated one.
• Keypads are separate accessories.
