Arcus-EDS

KNX Components & Smart Building Sensors from Germany

Arcus-EDS GmbH is a German manufacturer specialising in KNX components, sensors, gateways and display interfaces for smart building automation. With in-house development and production based in Berlin, Arcus-EDS designs robust KNX devices that support system integration, environmental sensing, metering and advanced control logic for both residential and commercial installations.

Focused on enhancing building performance and comfort, Arcus-EDS delivers products that help integrators connect, monitor and manage environmental data, along with specialist gateways and user interfaces for KNX systems. Arcus-EDS supports smarter building efficiency.

What Arcus-EDS Does

Arcus-EDS specialises in infrastructure components that make KNX automation systems flexible, yet powerful. The range includes:

Environmental sensors (temperature, humidity, CO₂ and VOC)

Specialised measurement sensors (soil moisture, fill level and water quality)

Gateways for communication and data integration (Modbus, M-Bus, DMX and IP)

Visualisation and control displays for KNX systems

Smart metering and impulse counters

These solutions enable KNX building automation projects to collect, process and visualise critical data, to enhance climate control, energy management and system coordination.

Arcus-EDS key product categories

Climate & Environmental Sensors

Arcus-EDS provides a wide variety of KNX-compatible sensors designed to measure and manage indoor environmental conditions:

Temperature, humidity & CO₂ sensors – Compact sensors for monitoring climate conditions and supporting HVAC automation.

VOC & multi-parameter climate sensors – Devices that provide combined readings of multiple air quality indicators for healthier indoor environments.

Soil moisture and temperature sensors – Used for irrigation control, landscape automation and moisture-based logic.

These sensors help integrate climate data into KNX systems — improving comfort, efficiency and ventilation strategies.

Gateways & Protocol Interfaces

Arcus-EDS gateways expand the connectivity of KNX systems beyond the bus, enabling automated monitoring and control:

M-Bus & P1 gateways – Connect meters and measurement devices (such as energy, water or heat meters) into KNX networks.

Modbus gateways – Allow communication between Modbus equipment and the KNX bus, ideal for industrial or third-party devices.

DMX gateways – Bridge DMX lighting systems with KNX logic for advanced lighting control applications.

KNX IP gateways – Enable ETS programming, data logging, visualisation and network-based access to KNX installations.

These interfaces are essential where data needs to be centralised or shared across protocols, or where specialist sensors and meters need to report into the building automation logic.

Displays & Visual Interfaces

Arcus-EDS also offers KNX touch displays and visualization panels — enabling users and system designers to interact directly with KNX systems through:

Touchscreen room controllers

Wall-mount displays for control and visual feedback

IP65 variants for harsher environments

Such interfaces support streamlined control and local interaction in projects ranging from homes to commercial spaces.

Where Arcus-EDS Fits in Your KNX Projects

Arcus-EDS components are advantageous when projects demand:

Advanced environmental monitoring (air quality, CO₂, humidity)

Integrated measurement and energy metering

Cross-protocol communication with third-party systems

Visualisation and user control beyond basic pushbutton interfaces

For smart homes, commercial buildings, public facilities and industrial sites, Arcus-EDS allows you to design smarter, data-driven, KNX automation projects.
