Nuki makes smart locks that fit over existing door cylinders, mainly for European doors, so the mechanical lock stays in place. The Nuki Smart Lock connects over Bluetooth, Thread and Wi-Fi, supports Matter and Apple Home Key, and can auto-unlock as the user approaches. Accessories include a keypad with fingerprint, a door sensor and the Opener for apartment intercoms. The company sells across Europe and is based in Graz.
