Automated opening and closing of windows and entrance doors

The SIEGENIA GROUP is one of the world's leading manufacturers of window and door fittings as well as ventilation and building technology. Insta developed a gateway for SIEGENIA that integrates the manufacturer's SI-BUS-capable devices into the KNX environment. Thus, motorized drives for windows and entrance doors communicate directly on the digital bus. This ensures both control and status feedback via the KNX system and straightforward KNX integration through the ETS configuration software. From now on, windows and entrance doors can be seamlessly integrated into automation scenarios with various devices and functions, with minimal effort. For instance, they can be set to automatically lock the front door at nightfall or to create coming- and leaving-home scenarios. Ideal for energy-saving night cooling during hot summer months are scenarios that automatically open and close windows. The compact design of the gateway allows for both concealed flush-mounted installation and mounting on a DIN rail.

Secure communication thanks to KNX data secure stack

To meet the ever-increasing security requirements against hacker attacks, Insta developed the first manufacturer-independent KNX Data Secure Stack back in 2020. This stack is also used in the SIEGENIA KNX Gateway. The devices come with a device certificate in the form of a QR code. Using this code, the installer can commission the devices via ETS according to KNX Data Secure. Through the implementation of KNX Data Secure and the monitoring of relevant development steps by our Cyber Security Officer, we can offer our customers a highly secure product.

Reasons to choose Insta for implementation

In collaboration with Insta GmbH, the customer particularly appreciated the smooth coordination. All communication was conducted at eye level, simply and solution-oriented.

A particular challenge in the project was the small installation space due to the DIN rail mounting. Insta mastered this challenge effortlessly by using an adapter. Due to its impressive development and manufacturing expertise, SIEGENIA deliberately relies on Insta and its development and production site in Lüdenscheid.
