Existing KNX installation, but no ETS project? We make it evolvable again
A building fitted with a working KNX system, but impossible to evolve because the ETS project file has been lost, or the original integrator can no longer be reached: this is a common situation for landlords and owners of commercial or professional property.
GET Conseil takes back control of this type of installation without replacing anything: an IP gateway listens to the live KNX telegrams, identifies the existing objects, then a Home Assistant integration makes the installation evolvable again — and controllable from a smartphone.
What we do
Taking back control without rebuilding everything
Listening to KNX telegrams
An IP gateway installed on the existing bus listens to the live KNX traffic and identifies the group addresses, without needing the original ETS file.Home Assistant integration
Once the objects are identified, the installation is connected to Home Assistant: scenarios, automations and new equipment become possible again.Smartphone control
The installation becomes accessible and editable from a mobile app, for you, your team, or your tenants/operators.What was blocking things until now
- ETS file missing — nobody could safely modify the installation any more.
- Original integrator gone — no technical documentation handed over when the building was acquired or taken over.
- Every change blocked — with no access to the project, any modification meant rediscovering everything by hand, or replacing it all.
What becomes possible again
- Modify an existing scenario without touching the physical installation or the existing wiring.
- Add new equipment over time, as the building's or tenants' needs evolve.
- Control and monitor remotely, from a smartphone, just like a modern home automation installation.
Frequently asked questions
What landlords and owners ask us
The ETS file for our KNX installation is lost — can it really be recovered?
Yes. An IP gateway installed on the KNX bus can listen to the live telegrams and identify the existing group addresses, without needing the original ETS file.Does the existing KNX installation need to be replaced?
No, that's the whole point of this approach: the physical installation stays in place, we simply connect to it via Home Assistant to make it usable again.Can the installation really be controlled from a smartphone afterwards?
Yes. Once integrated with Home Assistant, the installation becomes accessible via a mobile app, just like a modern home automation installation.Is this solution suitable for commercial property or multiple buildings?
Yes, this is a common situation for landlords and owners of professional property who inherit an equipped building without its technical documentation.Is this limited to KNX, or does it apply to other installations too?
The principle (listening to the bus, integration via Home Assistant) applies to other locked-down home automation installations, but KNX is the most common case due to a missing ETS project.Service area
