What are the differences between Smart Lock 2.0 and 3.0?

At first glance, the Nuki Smart Lock 3.0 and Nuki Smart Lock 3.0 Pro are still based on our tried-and-tested design concept of the retrofittable electronic door lock, which more than 200,000 satisfied customers have come to trust. However, a lot has changed under the hood:

- The Nuki Smart Lock 3.0 Pro is already equipped with a built-in Wi-Fi module. You no longer need a Bridge to control it remotely and integrate it into your smart home.
Note: The Bridge API is NOT supported by the integrated Wi-Fi module of the Smart Lock 3.0 Pro. To use the Bridge API, connect your Smart Lock 3.0 Pro with the Nuki Bridge. This way you can benefit from all supported integrations.
- The Nuki Smart Lock 3.0 Pro now comes with the Nuki Power Pack included as standard – for more power.
- By popular demand, our Smart Lock 3.0 Pro with aluminium ring is now available in white and black.
- Smart Lock 3.0 and Smart Lock 3.0 Pro now have a coloured LED that notifies you if your battery is low or there’s a fault.
- Both of the new generation Smart Locks support the new Nuki Door Sensor. The new technology behind the improved door sensor ensures a high level of reliability with minimal battery consumption. The Nuki Door Sensor has flexible installation options and is supported by the Nuki app. The door sensor is available in white, meaning it can be discreetly attached to your door frame.
- We have further improved the motor functions of our Smart Locks to offer you a convenient and carefree experience.
