nuki

Nuki is a brand of smart lock systems developed by Nuki GmbH, an Austrian technology company. The flagship product, the Nuki Smart Lock, is a retrofit device that attaches to the inside of a door and converts an existing mechanical deadbolt into a connected lock. It is controlled via a smartphone app (iOS and Android) and supports features such as remote unlocking, scheduled access, and automatic unlock when a paired device is near the door. Users can grant temporary access to guests and view activity logs.

The Nuki ecosystem includes the Nuki Bridge, which provides an internet connection to the lock for remote control and cloud-based features, and accessories such as the Nuki Opener (for integration with door entry systems in apartment buildings), a keypad, and a key fob. The system is designed to fit most standard European profile cylinders.

In operation, the lock communicates primarily via Bluetooth with registered mobile devices, while the Bridge enables remote control over the internet. Nuki emphasizes security and privacy, employing encryption for communications and supporting local operation even if the internet is unavailable.

Nuki markets its products mainly in Europe and increasingly in other regions, and it provides compatibility with various smart home ecosystems through the Bridge, including voice assistants and automation platforms.
