Building automation.
Finally without vendor software.
Plan your smart home from scratch. Open existing project files. Export to KNX, Loxone or Home Assistant, free, in your browser, no install.
No registration · No install · No license
Vendor software is the problem.
For homeowners. For integrators. For anyone without Windows or a license.
First in the world.
No other tool opens and visualizes building automation project files directly in the browser, without install, without an active bus gateway, without a license. What the industry had been missing for years is now here.
“Plan freely. Export wherever you want.”
Three apps. One platform.
No matter where you start. Viewer or Planner, you'll always end up in the Builder.
Viewer
You have a building automation installation and want to know what’s inside. Upload the project file, done. The analysis runs entirely in your browser. Without an account, no data is stored.
- Visualize building structure + topology
- Search datapoints & addresses, plain text instead of raw numbers
- Device list with manufacturer, type and details
- Processing runs locally in the browser, privacy by design
- Formats: .vnfr, .loxone, .knxproj
Planner
You plan from scratch. Building → floors → rooms → functions, step by step, no prior knowledge needed. The result is a complete bill of materials with prices and a valid project file for your target ecosystem.
- 25 function types, lighting, blinds, heating, presence, scenes …
- Automatic bill of materials with channel optimisation
- Export: .vnfr, Loxone, KNX (.knxproj), Home Assistant, CSV
- 19 room templates with sensible defaults
Builder
Configure
You have a project, now go deep. Design GA schemas, assign channels, map real devices from the catalogue, re-export for ETS. No wizard hand-holding, full control over every technical detail.
- GA schema builder, 3-level best practice or custom
- Topology editor, areas, lines, devices
- Channel manager, assign unused channels
- Re-export: .vnfr, .loxone, .knxproj, Home Assistant YAML, CSV
Vendor-agnostic. Protocol-neutral.
venfree doesn’t care about manufacturers, only functions. You export the result into the ecosystem that fits you.
KNX today · Loxone, Shelly, BACnet & more to follow, one open model for every protocol.
Who is venfree for?
Homeowner / Building owner
- You’re planning a new build or a renovation and want to know what smart home really costs, before commissioning an integrator.
- You have a smart home installation and don’t understand what’s in it or how it works.
- You don’t want to pay €80–€150/hour for every small change.
Integrator / Electrician
- You create quotes and bills of materials for clients, faster and more professional than Excel.
- You visualize projects right in the client meeting in your browser, no laptop with a Windows VM.
- You export valid project files in all common formats, as a clean starting point for your planning tool.
