KNX installation
in Cyprus — wired
smart home for
villas and new builds.
KNX is the industry standard for large residential automation. We install KNX systems for villas and new-build developments in Limassol — lighting, climate, blinds, security and access control on a single certified bus. Involvement from foundation stage. Full ETS programming and documentation at handover.
The open standard for building automation
KNX is an open international standard (ISO/IEC 14543) for building automation, maintained by the KNX Association and supported by over 500 certified manufacturers. Every KNX-certified device — regardless of brand — communicates on the same bus. Switches from one manufacturer, dimmers from another and actuators from a third all work together without adaptation or middleware.
The system runs on a dedicated two-wire TP bus cable run alongside power cabling to every switch position, sensor and actuator in the installation. Logic is distributed — each device is intelligent, and switches control loads directly without passing through a central server. If one device fails, the rest of the system continues to operate normally.
KNX has been installed in residential and commercial buildings since 1990. Installations from that era are still running today. This track record, combined with the open standard and global installer base, makes KNX the lowest long-term risk platform for large residential projects.
Why KNX suits villa projects in Limassol
Most premium villa developments in Limassol have construction periods of 18–36 months — sufficient time to plan and install a full KNX system properly. Large floor areas, multiple HVAC zones, extensive external lighting, pool control and gate automation all fall naturally within KNX's scope.
Cyprus has a significant number of internationally owned properties — villas purchased by clients who live abroad for much of the year. KNX is well suited to this context: the system runs entirely locally without cloud dependency, any certified installer can service it, and it is not tied to a software subscription or manufacturer's continued existence.
Large villas over 300sqm
KNX scales without complexity penalty. A 600sqm villa with 80 lighting circuits is handled the same way as a 300sqm villa with 40 — same bus, same programming tool, same commissioning process.
Developer projects
We work with developers building multiple units in Limassol. KNX documentation and ETS project files can be handed over to buyers' own integrators — no installer lock-in for the end client.
Internationally owned properties
No cloud dependency means the system works regardless of who is running it. Any KNX-certified installer worldwide can pick up the project file and continue work.
Complex scope projects
Multiple HVAC zones, pool and garden automation, extensive external lighting, energy monitoring and solar integration — all native KNX functionality.
What KNX controls in a villa
Scene-based control for every room and outdoor zone. Presence detection, daylight-linked dimming, time scheduling and manual override from wall panels or app.
Room-by-room temperature control integrated with fan-coil units, underfloor heating and split systems. Scheduling, presence-based setback, and remote control.
Somfy and KNX-native actuators for roller blinds, venetian blinds and external shutters. Sun-tracking automation and integration with lighting scenes.
Integration with video intercom, gate automation and Ajax alarm. Arrive home scene: gate opens, alarm disarms, entrance lighting turns on.
Real-time consumption per circuit via KNX metering. Integration with solar inverters and EV chargers. Consumption history and reporting.
Pool pump scheduling, lighting zones, irrigation control and outdoor socket management — all on the same KNX bus.
How a KNX installation works
Design & specification
We review floor plans, agree switch positions, panel locations and conduit routes. A full cable schedule and device list is produced before any cabling begins. This document is shared with your main contractor for co-ordination.
First-fix cabling
KNX TP bus cable and power cables are run during the construction first-fix phase. Conduits are specified for future cable addition. Panel enclosures are sized and located.
Second-fix installation
Devices are installed — switches, sensors, touchscreens, actuators and panel components. Bus cable connections are made and the system is powered for initial testing.
ETS programming
Each device is addressed and programmed in ETS. Group addresses define how switches and actuators communicate. Scenes, schedules and automation logic are built and tested.
Commissioning & handover
Full system test across all circuits. Visualisation interface configured. Client walkthrough. ETS project file and as-built documentation provided at handover.
Common questions about KNX
How much does KNX cost in Cyprus?
A full KNX installation for a villa — covering lighting, climate, blinds and security integration — typically runs €20,000–50,000 depending on the number of rooms, circuits and devices. This includes all hardware, cable, panel build, programming and commissioning. We provide a detailed itemised quote after a site visit or floor plan review.
Who programs KNX?
KNX is programmed using ETS (Engineering Tool Software), the industry-standard tool used by certified KNX installers worldwide. All our installations are fully programmed, documented and handed over with a complete ETS project file — which any KNX-certified installer can open and modify in the future.
Can KNX be added to a finished building?
Technically possible but expensive. KNX requires a dedicated bus cable to every switch position and actuator — in a finished building this means opening walls and replastering. For retrofit projects, Home Assistant with ZigBee wireless devices is almost always the better approach. If you want wired KNX later, plan the conduits now.
How long does a KNX installation last?
KNX installations from the 1990s are still operational. The standard is backward compatible — devices from different generations and different manufacturers work together on the same bus. You are not buying into a product cycle with planned obsolescence.
When should I contact you during a new build?
At schematic design stage — before floor plans are finalised. The earlier we are involved, the less it costs. Conduit routing, panel locations, switch box positions and cable specifications all need to be agreed before first-fix begins. Involving a KNX integrator after walls are closed adds significant cost.
Is KNX better than Loxone?
They suit different projects. KNX is manufacturer-independent, more complex to program and more expensive — but the most reliable long-term platform for large installations. Loxone is faster to commission, has a better native app and costs less — but ties you to one manufacturer. See our full comparison at /guides/knx-vs-loxone.
Involved in a new build in Cyprus?
Contact us at design stage — before conduits are specified. The earlier we are involved, the better the result and the lower the cost.
