KNX Project Rescue & Takeover
Original installer unreachable, ETS file missing, panel undocumented. We map the bus, recover the project, verify every point, and hand you a clean baseline to continue from.
How the rescue works
On-site bus diagnostics
We connect to the KNX bus and scan physical addresses, line couplers, and topology to build an accurate picture of what's actually installed — independent of any existing paperwork.
ETS project recovery
If the original ETS project file is missing or unusable, we reconstruct it from the device scan: physical addresses, group addresses, and topology rebuilt from the installation itself.
Function verification
Every actuator, sensor, and controller is tested against as-built behavior — switch by switch, output by output — so the new project reflects what the system actually does, not what old records claim.
Documented handover
You receive a current ETS project plus physical documentation — panel layout, device list, group-address structure — before we continue the outstanding scope.
Built for continuation, not critique
The bus doesn't lie
Every KNX device carries its own address and logic on the TP bus. Even with zero documentation, the physical installation itself is the source of truth we work from.
Non-destructive bus scan
Physical address and topology recovery without disturbing live functions or requiring downtime beyond the diagnostic window.
Reconstruction from device scan
When there's no ETS file to recover, we rebuild the group-address and topology structure directly from the devices on the bus.
Manufacturer-agnostic verification
KNX Association certification means a mixed-brand installation is standard practice — we work across sensor and actuator combinations regardless of original vendor.
As-built documentation
Panel labelling, device inventory, and topology diagrams delivered alongside the ETS project, so the next engineer isn't starting from zero either.
Clean handover, no rework mandate
We verify and document what's there — we don't propose ripping out working infrastructure to fit our own preferences.
What's included
A defined scope to take a stalled project from unknown state to a documented, continuable baseline.
- On-site KNX bus diagnostics and physical topology scan
- ETS project recovery or full reconstruction from device scan
- Function verification of every actuator, sensor, and controller
- Panel and cable labelling audit with as-built documentation
- Handover package: current ETS project file plus physical documentation
Frequently asked questions
What if the ETS project file is completely lost?
We re-scan the bus for physical addresses and existing devices, then reconstruct the group-address and topology structure from that scan. It takes longer than reading a file, but it's a reliable path back to a working project.
Does this involve auditing or criticizing the previous installer's work?
No. We treat this as a continuation service: our focus is mapping current state and closing the documentation gap, not evaluating who did what before.
Can you work with a mix of KNX devices from different manufacturers?
Yes. KNX Association certification guarantees interoperability across brands, so a mixed-manufacturer installation is standard practice, not an obstacle.
What do we receive at handover?
A current ETS project file, a physical topology map, panel and device labelling, and a documented group-address structure — everything needed to continue the outstanding scope.
Can PanelCraft continue as integrator of record after the rescue?
Yes — the rescue is typically the first phase before we continue the remaining installation, commissioning, or maintenance scope.
Stalled KNX project?
Send us the site details and whatever documentation exists — even none. Our engineers will scope the diagnostics and recovery before continuing your project.
