More than a visualisation
The software layer that brings your installation together.
A modern home contains dozens of technologies. SmartEner turns that complexity into one understandable system that runs locally, remains well documented and can grow over time.
We use KNX as a dependable foundation and connect HVAC, energy, EV charging, pool technology and customer-specific systems where needed.

A home is not a collection of separate apps.
The best automation feels natural. Functions respond together to time, presence, energy, comfort and safety — while residents always remain in control.
- ✓ One consistent interface
- ✓ Logic remains available locally
- ✓ Technologies share context through KNX
- ✓ Expandable without starting over

Our principles
Open where possible. Local where it matters.
Technology should still be understandable, transferable and maintainable in ten years’ time.
Local-first
Essential control continues to operate locally, even when the internet or an external service is unavailable.
Documentable
Clear structures, names and handover so an installation never becomes an opaque black box.
Targeted custom work
Custom software only where it genuinely adds value to comfort, management or energy.

Open Energy Management
KNX and energy in the same control system.
Our Energy Manager combines live measurements, forecasts and dynamic tariffs. It controls the battery, EV charger and climate locally, then schedules the washing machine, tumble dryer and dishwasher for low-cost or solar-rich periods — based on your preferred finish time and always with manual control.
SmartEner mobile
Your Energy Manager, always within reach.
Follow energy flows, review planning and control assigned household appliances from the SmartEner EM app.
