Open the KNX plannerHow the KNX planner works
Set up your floors and rooms, or start from a demo house. No installation, runs in the browser.
Per room, choose what you want: switched and dimmed light, blinds, heating, presence and more.
venfree calculates the actuators, channels and sensors automatically, with real net prices and export.
One planner for every manufacturer
Unlike a manufacturer tool, venfree is neutral. The catalog covers Gira, Jung, MDT, Hager, Theben, Zennio and more, and you choose the manufacturer per actuator type. So you compare devices and prices across brands instead of being locked into one.
Browse the device catalogFree and without ETS
You do not need an ETS license to plan and price KNX. venfree runs in the browser, no install, no account. Commissioning still needs ETS or an integrator, but the planning, the device list and the cost estimate are free with venfree.
