Blind Control for Smart Rooms

onework combines sun position, cloud cover, usage, and property-specific parameters into a dynamic shading logic. Blinds and other shading systems are controlled as needed and integrated into the overarching building automation system.

Smart Building Monitoring Redefined

Sun protection that does more than just respond to fixed thresholds

Traditional shading systems often operate with fixed lux thresholds and are therefore sensitive to short-term fluctuations in brightness. This can lead to unnecessary movements and erratic system behavior.

Instead, onework relies on a dynamic brightness assessment. The sun’s position, cloud cover, building facade orientation, and building occupancy are evaluated together to ensure that shading operates in a reproducible manner and only responds when functionally necessary.

Situation

Shading often reacts
too late or too frequently

Traditional blind control systems often operate with fixed brightness thresholds. Short-term fluctuations caused by changing cloud cover can thus trigger unnecessary movements and lead to erratic system behavior that is difficult to plan for.

At the same time, the sun’s position, building facade orientation, building occupancy, and thermal influences must all be considered together. Controlling individual blinds in isolation often falls short in this regard.

Solution

Dynamic Shading Logic
Instead of rigid thresholds

centrally evaluates actual lighting conditions, cloud cover, sun position, facade orientation, and building occupancy, and uses this data to generate the necessary control commands. These commands are transmitted via KNX-SMI gateways to the connected blind drives and implemented across all zones.

This results in consistent responses, fewer unnecessary movements, and shading that can be coordinated with the lighting and climate control functions of the building automation system.

Reproducible

Identical conditions lead to identical responses and, consequently, to predictable system behavior.

Benefits

Shading that combines comfort and energy efficiency.

Greater visual comfort

Venetian blinds adjust automatically to the sun's position, cloud cover, and room usage. This helps reduce glare without unnecessarily blocking out natural light.

Visualization

The Guard is a digital twin of the KNX building. This allows you to see on a screen from a central location which device is currently doing what and where malfunctions are occurring.

How the Blind Control System Works

Sensors, central logic, actuators, shading, and operation all work together to form a coordinated blind control system.

It records the sun's position, brightness, cloud cover, wind, precipitation, and other relevant environmental data.

using (86)

Processes weather, usage, and room data and handles the central shading logic.

They execute position, louver, and movement commands and constitute the operational level of the shading control system.

using (87)Allows you to manually adjust the position of the blinds, scenes, and other room functions right in the room.

Open to Various Actuators

Control is not limited to SMI. Depending on the project, other suitable KNX actuators and drive solutions can also be integrated. The key is integration into the central automation logic of onework CORE.
