IP BACKBONE
KNX IP Control Cabinets
KNXnet/IP · ISO/IEC 14543
KNX IP carries the KNX bus over standard Ethernet. We design and build custom KNX IP control cabinets with certified KNXnet/IP routers — ready for fast building backbones, secure remote commissioning and live visualisation.
What is KNX IP?
KNX IP (KNXnet/IP) is the IP layer of the KNX building-automation standard. Instead of carrying telegrams only over a twisted-pair (TP) bus, it tunnels and routes them over the building's existing Ethernet network.
In practice, KNX IP routers couple individual TP lines into one logical installation over IP. This gives large buildings a high-speed backbone, removes TP cable-length limits between floors, and opens secure remote access for commissioning, diagnostics and visualisation servers.
Why choose KNX IP for larger buildings
On a multi-floor building or campus, a pure TP topology becomes slow and hard to service. KNX IP solves this by moving line-to-line traffic onto Gigabit Ethernet, so a press in one wing reaches an actuator in another without bus bottlenecks.
Because KNX IP reuses the network you already have, it is the cost-effective way to scale a KNX installation, add a touch-panel visualisation server, or let our engineers commission and support the system remotely.
Key capabilities
High-speed Ethernet backbone
KNX IP routers couple dozens of TP lines over Gigabit Ethernet with no bus bottlenecks.
KNX IP Secure
Encrypted, authenticated telegrams keep remote access and IP traffic safe.
Remote commissioning & support
Engineers reach the installation over a secure VPN — no site visit for changes or diagnostics.
Live visualisation
Servers, dashboards and mobile apps read and write the bus directly over IP.
Line & area coupling
Clean IP coupling of TP lines replaces long, length-limited backbone cables.
Future-proof infrastructure
Reuses the building network and scales from a villa to a campus.

- ✓Fully wired, labelled and bench-tested before dispatch
- ✓Declaration of conformity, test report and as-built documentation
KNX IP cabinet cost and lead time
A KNX IP control cabinet is quoted per project, because the price depends on the number of TP lines, the IP routers and the field load. As a guide, a residential KNX electrical distribution cabinet with an IP backbone typically starts around €3,000–8,000; multi-line commercial cabinets are quoted individually.
Standard production and dispatch is 10 to 15 working days from a confirmed order and approved design. Every cabinet is CE-marked, built to EN IEC 61439 and delivered ready for a local electrician to connect the incoming and outgoing cables.
Frequently asked questions about KNX IP
What is KNX IP and how is it different from KNX TP?
KNX IP (KNXnet/IP) carries KNX telegrams over Ethernet, while KNX TP uses a dedicated twisted-pair bus. KNX IP is used as a fast backbone to couple TP lines, enable remote access and connect visualisation — the room-level wiring usually stays on TP.
Do I need KNX IP Secure?
For any installation reachable from the internet, yes. KNX IP Secure encrypts and authenticates IP telegrams so remote commissioning and access cannot be intercepted or spoofed. We enable it by default on cabinets with remote access.
How much does a KNX IP control cabinet cost?
It is quoted per project. A residential KNX electrical distribution cabinet with an IP backbone typically starts around €3,000–8,000 depending on the number of lines, routers and devices. Commercial projects are priced individually after a free consultation.
Can you ship assembled KNX IP cabinets to Germany, Poland or France?
Yes. We deliver CE-certified, pre-tested KNX IP cabinets across all EU countries, usually in 3–7 working days. The cabinet arrives plug-and-play — a local electrician only connects the incoming and outgoing cables.
Can KNX IP integrate with visualisation, Loxone or Home Assistant?
Yes. KNX IP exposes the bus over the network, so visualisation servers, dashboards, Loxone and Home Assistant can read and control it. We prepare the cabinet and IP interfaces so third-party systems connect cleanly.
