The Type axis of KNX Certified Products segmentation classifies offerings into Controllers, Sensors, Actuators, Communication Modules and Power Supplies. Controllers—including central processing units and distributed line couplers—form the logical core of a KNX system, directing data traffic and executing automation scripts; they contribute the largest share of revenue due to their essential role in network topology. Sensors (e.g., temperature, occupancy, illumination) generate the input data that drives decision‑making, and their proliferation in both retrofit and new‑build projects fuels incremental market growth. Actuators translate commands into physical actions such as dimming lights or adjusting valve positions, representing a substantial portion of unit sales. Communication Modules provide protocol translation and wireless connectivity, increasingly important as legacy installations migrate to IP‑based backbones. Finally, Power Supplies ensure stable bus voltage across the KNX topology, a prerequisite for reliable operation. Together, these product types constitute the comprehensive KNX Certified Products segmentation, each layer adding distinct value to the overall market size.
