Understand
instead of programming.

Your students should be able to read and understand project files, not struggle with engineering tools not built for the classroom.

venfree Edu gives you back the time you need for what matters: deeper project thinking, real understanding.

The problem in the classroom

The ETS is an engineering tool. Not a teaching tool.

Expensive licences

Every student PC needs an ETS licence. School budgets are limited, money better spent on hardware or teaching materials.

Windows-only

The ETS only runs on Windows. Schools with mixed systems or tablets have no option.

Complex tool, scarce classroom time

Instead of teaching project logic, valuable class time flows into introducing an engineering tool not built for classrooms.

All or nothing

You can't show students a project without also exposing security keys and device configurations. No granular control.

No understanding goal

Students learn to click buttons but not to understand why a group address is linked to a room. Engineering tools optimise for engineering, not for learning outcomes.

The shift in perspective

Fewer ETS clicks.
More project understanding.

When students need to understand a KNX project, they don't need full ETS access. They need a clear, focused view: topology, group addresses, room structure. venfree gives you exactly that, and gives you your classroom time back.

What venfree Edu can do

Everything you need for the classroom. Nothing that gets in the way.

KNX & Loxone available · Shelly & more coming

Open project files without a licence

Students import a .loxone or .knxproj file and immediately see: topology, group addresses, devices, room structure. Clear, organised, readable, without a single ETS licence.

Health check as a teaching tool

Give your students a .knxproj with intentional errors. venfree finds them: missing links, inconsistent topologies, orphaned devices. A ready-made classroom exercise.

Smart export in class

Show students how to export a project for different recipients: What does the homeowner see? The facility manager? The manufacturer support? Granular control as a learning topic.

Every platform, every device

Windows, macOS, Linux, browser. Whatever your school has, venfree runs on it. Desktop app for full offline capability, web version for quick onboarding.

Data stays at school

Desktop app: No data leaves the device. No cloud, no upload, no tracking. Privacy as it should be, especially with underage students.

My students should understand why group address 1/2/3 controls the hallway light, not where to find it in the ETS. venfree shows exactly that.

I learned KNX at vocational school myself and know the ETS from my training. I'm building venfree because I know there has to be a better tool, for students, for teachers, for the whole industry. Built in Germany, hosted in Nuremberg, GDPR-compliant.

I'll show you.

No webinar, no funnel. A short introduction, in person at your school or via video call. You decide afterwards.
