How to Retrofit KNX in an Existing Building
A practical KNX retrofit method covering surveys, TP and RF strategy, existing circuits, panel work, phased cutover, risk control, commissioning, and handover.
Engineering guides for topology, wiring, group addresses, power supplies, and building-level planning.

A practical KNX retrofit method covering surveys, TP and RF strategy, existing circuits, panel work, phased cutover, risk control, commissioning, and handover.

An engineering workflow for KNX lighting control covering circuit schedules, switching and dimming methods, scenes, sensors, status feedback, fail states, and testing.

A step-by-step KNX commissioning workflow covering design freeze, electrical checks, addressing, ETS downloads, functional tests, integration, acceptance, and backup.

A transparent way to estimate KNX project cost from functions, circuits, rooms, integration, cabinet work, commissioning, and handover—not device price alone.

What to include in KNX project documentation so owners, integrators, and maintenance teams can support the system long term.

Plan cabinets for power, bus wiring, actuators, gateways, labeling, ventilation, and service access in professional KNX installations.

Plan KNX HVAC zones, sensors, actuators, schedules, and user controls so comfort and energy savings do not conflict.

Design lighting scenes for homes, hotels, offices, and public buildings without creating confusing controls or difficult commissioning files.

Avoid bus polarity errors, poor cable routing, missing documentation, voltage drops, and cabinet layout problems before commissioning starts.

Create group address structures that are readable, scalable, easy to troubleshoot, and consistent across homes, hotels, and commercial projects.

Plan KNX bus lines, power supplies, line couplers, device counts, voltage margins, and future expansion without overcomplicating the project.
