KNX Software Alternatives to ETS: Tools That Speed Up Commissioning
ETS is the standard for KNX commissioning — but expensive, complex and oversized for many projects. This overview shows which alternatives exist and when switching or supplementing is worth it.
Why ETS is criticized
ETS holds a quasi-monopoly status and every electrician feels it. Three main criticisms come up again and again.
License costs
ETS Professional costs over €1,000 per license. For small projects this is hard to justify.
Steep learning curve
Anyone who doesn't use ETS regularly has to relearn it each time. Complex group-address logic is off-putting.
Outdated UI
The interface feels like the 2000s. Modern tools are significantly more productive.
The main alternatives and supplements
Pure KNX programming requires ETS — but for planning, visualization and logic, there are strong alternatives.
KNX planning tools
Tools like myElectricPlan supplement ETS with upstream planning: which actuators where, which group address structure, which rooms.
Logic engines
Node-RED, Home Assistant or Edomi handle complex logic that's only laboriously expressible in ETS.
Visualization
Instead of expensive KNX visualizers: ioBroker, Home Assistant, Loxberry — flexible and usually cheaper.
Device configuration tools
Some manufacturers offer their own tools for commissioning without ETS (e.g. MDT). Worth it mainly for simple systems.
When is which solution worth it?
Small project (single-family house, < 50 actuators)
ETS Lite (free up to 20 devices) plus a planning tool for group addresses is often enough. For more devices: buy ETS Professional or subscription.
Medium project (multi-family house, commercial)
ETS Professional plus separate visualization tool and logic engine. Task separation saves time long-term.
Major project with complex logic
ETS for bus communication, Edomi or logic server for scenes and automation, ioBroker for visualization. Hybrid setups are often strongest here.
Tips for the hybrid workflow
Plan outside of ETS first
Walk through rooms, devices and group addresses in a planning tool first. ETS is for programming, not brainstorming.
Separate documentation
Use an external tool for terminal plan, actuator list and cabling. ETS is unsuitable for this.
Keep visualization separate
Visu software decouples KNX logic from the user interface. Switching later is easier.
Conclusion: no ETS alternative, but strong supplements
For KNX programming, ETS remains the standard. But around it, there are plenty of tools that speed up your work — from planning to visualization.
💡 Tip: Strictly separate planning, programming and visualization. Each discipline has its own best tool.
Simplify KNX planning
With myElectricPlan you plan KNX rooms, actuators and group addresses before ETS programming. Saves hours and reduces errors.
