Open doors from your app! Enhance your existing setup with the API interface from KIWI.


You can integrate KIWI into your own app

If you have an app and the users of this app have to get through doors, then KIWI is the perfect addition to your solution. Conceivable examples include apps for communicating with tenants, managing the services of tradesmen, supervising parking garages, or organizing care staff.

With the KIWI API you can use simple HTTPS access via the Internet to manage access rights for front entrance doors, apartment doors, and basement doors as well as remotely open doors. The KIWI API can be used for integration into existing systems and for application development.


Added function as the new feature: digital door opening.

Case Study


Mareon and KIWI open doors for technicians

KIWI and Aaeron have successfully combined two innovations for the housing industry. Since the end of 2017, KIWI functionality has been integrated into Aareon’s service portal for housing industry technicians, called Mareon. With this, the process of placing an order with a technician becomes more automated and digitalized.


If damage is reported, staff can forward the order via an ERP system to the respective technician, where they can receive all details directly. Thanks to KIWI, the key delivery step can be eliminated; the technician is granted immediate access to the door when accepting the order. Using the Mareon app, the technician can open the KIWI-equipped door using their smartphone. Once the order is completed, the door access is automatically revoked.


Together with Mareon and KIWI, two technologies have been combined to streamline the processes of housing and property management companies. Thanks to KIWI API integration, this can be achieved without additional data server infrastructure or the use of separate software applications. A demonstration can be seen in the video (presented in German).


Allthings – the digital service platform

The digital service platform from Allthings provides modular applications for property users that bring together digital functions and services for better living and working in buildings. Thanks to the modular design of the Allthings app, it can be loaded with precisely the digital services that are of particular interest to users and housing cooperatives – from local market places to the integration of data from ERP systems and the incorporation of other providers of solutions, such as KIWI.


WATTx – Expanding the KIWI features

Wattx proves the possibilities of the open KIWI API interface. The young company is helping technology startups. With the use of KIWI, it is also focusing on technological progress in everyday office life. Employees use the KIWI App to open the office entrance door. Since in contrast to the opening with the KIWI transponder no handsfree mode is possible, WATTx considered an alternative to get even more comfortable with the bike in the office. What works with the latest smartphone, but would also be handy for unlocking the front door: opening via face cam with face recognition.


The idea for the extension of the KIWI function arises in an internal hackathon by WATTx. WATTx designs a facial recognition software that checks a total of 128 facial dimensions. These are checked with the created library of photos of authorized employees. The Raspberry Pi mini-computer, called the WATTx KIWI Pi, and the entrance-level camera connect to the electronic locking system via the KIWI API. If the face detected by the camera matches the contents of the data library, KIWI automatically opens the office door. The implementation took only a few days and the cost of the Raspberry Pi and the camera amounted to less than 50 euros. If there is no match with the registered detection data, the system automatically saves an image of the possible intruder for later review.

cunio – The communication platform

cunio is an open communication platform for tenants, property owners and its organization. Cunio simplifies the management of real estate for all concerned: inquiries, services, bulletin board entries, offers, leases – all this can be exchanged in a structured way.


cunio offers various communication channels: whether tenant app, telephone assistant, e-mail, SMS or WhatsApp – the tenant decides for themself which communication channel they prefer. The property owner receives the information bundled on cunio.


The KIWI integration extends cunio’s service with digital building access.

Satisfied Users


Manfred Bausch
Head of product development at Allthings

“The integration of KIWI provides a typical example of how an open platform like Allthings is capable of incorporating a wide range of smart services, which means that we are continually able to offer our customers new services that are of value in many different ways.


KIWI is a particularly good example, because the property is enhanced by the digital solution while simultaneously improving the comfort of residents and service providers working within the building. This is precisely in keeping with our philosophy.”

KIWI can be integrated into many different systems!
