Nuki

Nuki, headquartered in Graz, Austria, is the leading European smart lock brand. Their retrofit design mounts over existing Euro-profile cylinders, making installation tool-free and reversible — ideal for European renters. The Nuki Smart Lock Pro 4.0 was among the first locks to ship with native Matter over Thread support, enabling seamless integration across Apple Home, Google Home, and Amazon Alexa without proprietary hubs. Nuki's standout feature is its precise auto-unlock via Bluetooth geofencing — the lock detects when you approach and unlocks automatically. The Pro model includes a rechargeable battery pack and built-in Wi-Fi for remote access.
