Frequently asked questions

  • How is the Nuki Box different from the Nuki Opener?

    Both Nuki products are primarily suitable for opening the main entrances to apartment buildings. The Nuki Opener is connected to the existing intercom in the relevant apartment. This means that only the residents of this unit can open the main entrance to the building. The Nuki Box, on the other hand, is connected directly to the opening system of the main entrance door. This means that all residential units in the building can be authorised to open the main entrance of the building.
  • Where can I use the Nuki Box?

    The Nuki Box is an electronically controlled potential-free relay that replaces a variety of switches and can be controlled remotely. It can be used to lock electronically controlled locking systems, such as entrance to apartment complexes, premises of associations, company buildings or garages. The Nuki Box can also be used on other opening systems, provided there is a sufficient 2G GSM signal and a power supply (8-36 V AC/DC).
  • Do I need a Bridge to be able to use the Nuki Box?

    No. The Nuki Box comes with a SIM chip (eSIM), which means it has continuous 2G GSM reception.
  • How do installation and start-up work?

    Installation and start-up both require prior electrical knowledge. On top of that, sufficient 2G GSM reception and a power supply must be ensured at the point of installation. Further information on installation can be found at: nuki.io/box-manual. For start-up, please follow the steps at: nuki.io/box-setup
  • How is my data protected as a tenant or member of an association with the Nuki Box?

    With the Nuki Box, it is possible to create multiple authorisation levels. Administrators can create units (e.g. for tenants, members, service providers, etc.), who in turn can assign individual permissions themselves. This significantly reduces the administrative outlay for property owners. The Nuki Box administrator can also delete permissions at any time (for example, if a tenant moves out of the apartment). This will also delete the permissions granted by the tenant. In the activity log, the administrator can see all locking processes. They are, however, anonymised, so resident privacy is always maintained. For example, residents who are assigned to a unit can in turn assign individual permissions to family and friends. These can also be deleted or edited at any time. In the activity log, tenants can see their own locking processes and those of the people they have authorised.
  • Can I still lock the door with the key?

    Yes. If you’ve forgotten your smartphone or the battery is dead, you can open the entrance door with the Nuki Bluetooth Fob, for example. You can also log into your Nuki Web account using any internet-enabled device and use it to unlock and lock the door. In an emergency, you can also lock your door with your conventional key.
  • Which APIs and integrations can I use with the Nuki Box?

    The Nuki Box can be used with numerous APIs and can be integrated into a variety of smart home systems. You can currently use the following integrations and APIs with the Nuki Box:You can currently use the following integrations and APIs with the Nuki Box: APIs: Nuki Web API Since the Nuki Box is not compatible with the Nuki Bridge, integrations based on the Bridge API cannot be used.

  • What happens to the data usage fees after 5 years?

    The Nuki Box costs a one-time fee of €349, which includes the costs for an internet connection via SIM card for 5 years. There are no additional costs for residents or tenants who simply install the Nuki app for use. There are also no costs for service providers – all that is required in this case is the installation of the Nuki Partner app.

    The connection costs are included for 5 years. After 5 years, the current standards and costs for internet connections will be assessed.
