    Why does the Nuki 4.0 Pro Lock have this price?

    The Nuki Pro 4.0 smart lock is the most advanced model in the range. It integrates a Bridge that connects to your WIFI network and therefore, you can open or close the door of your home from anywhere in the world without having to purchase an additional Nuki Bridge.

    But that’s not all. Nuki Smart Lock PRO 4.0 supports MQTT, so you can use it directly with home automation hubs like Home Assistant or Jeedom without relying on the cloud.

    It is also compatible with Matter (over Thread). This means that you can integrate it with a Thread Border Router such as a Nest Hub (2nd gen.) or Nest Hub Max voice assistant or a Home Assistant or Jeedom home automation hub so that once linked with this “Thread Border Router”, you will have control of your Nuki 4 PRO lock from any Matter device: Alexa, Google Home, Apple, Jeedom, Home Assistant and more.

    And another detail is that this Nuki Smart Lock PRO 4 lock incorporates a rechargeable battery, unlike other models in the range that run on four standard AA batteries.

    Tutorial on how to use the Nuki 4 PRO Lock

    To begin with, although Nuki Smart Lock PRO 4 is called a smart lock, it is actually a Key Turner, i.e. it will not replace your traditional cylinder in your house, but simply turns the key that is placed inside your house.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    This is an essential first detail to bear in mind.

    If you replace your traditional cylinder with a smart cylinder, what would happen if there is a device failure?

    Smart Lock Nuki Smart Lock PRO 4 Generation

    Then you will probably have to call in a professional to change your lock, which will cost you a lot of money.

    But what Nuki does is to turn your key inside the house, so you keep the traditional use, i.e. you will be able to open from the outside with your traditional key, which is very important to always have the possibility to do it this way.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    In order to be able to open from the outside with a key, since you have a key inside the house with Nuki, you must have a double clutch cylinder.

    It is not compulsory, but it is highly recommended, since in this way, you can open or close the door with your key from the outside while having another key inside the house.

    This has been the case of a user of a house that is implementing different smart devices.

    By the way, in other content we have seen that a user has implemented a smart lock to give access to his children so he can keep track of when they come home and not have to give out keys.
    He also plans to rent out his house when he goes on holiday, so he has more flexibility to share access with Nuki without having to share keys.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    This is the case of another user that we have also seen in other content, who in addition to managing the blinds, air conditioning and Zigbee kibble dispenser for his cat, all thanks to the Jeedom home automation hub, also adopted the Nuki smart lock as he often goes on holiday to other homes and shares access to his home with the Home Exchange platform.

    And Nuki has found it a very interesting solution and we are going to see how to set it up.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    We wait a few seconds.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    Done, the lock is linked to our application.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    We can activate or not the access to our location, this is very interesting for the Auto Unlock function that allows us to open the door of our house when we are arriving in front of it, without taking out the phone.

    We can activate notifications or not.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    Now, we can calibrate our lock to open and close our door correctly.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    Now, we can try unlocking or locking our door to verify that it is correctly calibrated.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    In my example, my door has a doorknob and from the outside, even if I open the lock with Nuki, as I have this doorknob, I would not be able to enter the house.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    Of course, Nuki manages this criterion and for this, we must go in the settings, features and configuration, general, choose the door handle and select the option “door handle”.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    And as you can see, when you open the door, the door handle also opens for a few seconds.

    Smart Lock Nuki Smart Lock PRO 4 Generation

    At the settings level, we can also create different users with different access criteria.

    And with Nuki, you can configure other devices in the range such as the Opener which is to open the door of the building from your phone, the keypad or fob which are other methods to open the door as I mentioned, the door sensor to have the confirmation that the door is properly closed or the bridge that in the case of the Nuki Smart Lock Pro 4 is not necessary because it already integrates this bridge.

    Frequently Asked Questions about Nuki Smart Lock 4th Generation

    How long does the battery of the NUKI Smart Lock 4.0 Pro last?

    It depends on the frequency of use but in theory, the battery life of the Power Pack included in the Smart Lock Pro 4.0 is 6 months.

    Is a Nuki smart lock secure?

    To begin with, it is important to understand that the installation of your Nuki smart lock is done on the inside of your home, which means that from the outside it is not visible that you have a smart lock. Unlike a traditional key that can be lost or stolen, allowing an intruder to gain access to your home (if you haven’t changed the lock), with a smart lock, if the associated phone is lost or stolen, you may have a security password enabled on the device.
    In addition, you can block access to your smart lock from the Nuki interface, either from a computer or from another phone. Finally, because your Nuki smart lock’s communications are encrypted, it would be more difficult for an intruder to gain access to your home by hacking into the lock than by simply forcing a door or window.
