Frequently asked questions about KNX in Luxembourg

As an initial guide, a complete residential KNX installation in Luxembourg often falls between EUR 90 and EUR 250 per m² including VAT, depending on the selected functions. For a 200 m² home covering lighting, heating and blinds, budgets frequently range from EUR 20,000 to EUR 50,000 including 17% Luxembourg VAT. This is a planning range, not a price that applies to every project.

Yes. You can start with the simulator for an indicative range, send your request by email or book an on-site appointment directly.

Readable plans and a clear function list are often enough for an initial design and estimate. A site survey is useful when existing wiring, cable routes, switchboard space or coordination between trades must be verified.

Yes. KNX is suitable for both renovation and new construction, provided the design reflects the available cable routes and the planned level of building work.

For a single-family home, KNX work is spread across several construction phases: design, wiring, switchboard and device installation, ETS programming, testing and handover. It is therefore rarely a continuous block of work on site.

The handover content is defined in the quote. For a complete assignment, it normally includes an ETS project backup, the group address structure, the device list and a description of the implemented functions.

KNX is an open international standard for home and building automation. It connects lighting, heating, ventilation, blinds, sensors and controls within one shared architecture.

The right choice starts with the building. For a new build or major renovation, a wired KNX bus provides a stable and expandable infrastructure. In a finished property, wireless technology can greatly reduce disruption.

A correctly designed KNX installation normally continues to run its local functions if the original integrator stops trading. Another KNX professional can then diagnose, maintain and extend the system.

KNX can reduce energy use, but no credible percentage can be guaranteed without knowing the building, its equipment and how it is used. KNX is the control platform; savings come from functions that are implemented and tuned correctly.

Yes. A visualisation system or gateway can control lighting, heating, blinds and scenes from a phone or tablet.

Yes. Correctly programmed local functions such as lighting, heating and blinds continue to operate on the KNX bus without an Internet connection.

A KNX installation can make a property more attractive, but it does not guarantee a specific increase in value. A buyer must be able to understand, operate and maintain the system.

Yes. KNXExpert acts as an external KNX integrator for small and medium-sized electrical contractors that want to deliver KNX projects without building a complete in-house ETS engineering team.
