Wired (Legrand Vantage/KNX) vs Wireless Home Automation: Which is Right?

Written by u.haus Technical Director

Selecting the core infrastructure protocol is the single most critical decision in home automation planning. Should you lay dedicated BUS wiring or rely on wireless mesh networks?

Wired Systems (Legrand Vantage / BUS): Built to Last Decades

Wired systems run low-voltage twisted-pair BUS cables from a central control rack to keypads and dimming panels. Key advantages include zero Wi-Fi interference, instant sub-millisecond scene switching, and 25+ year lifespan reliability.

Wireless Systems (Legrand Arteor IoT / Zigbee): Flexible Retrofitting

Wireless smart switches replace existing mechanical switches using standard electrical boxes. They communicate over encrypted wireless mesh, allowing installation without damaging existing wall plaster.

At u.haus, we frequently design hybrid architectures — utilizing wired Vantage control for main living areas and high-load lighting, alongside wireless IoT extensions for guest bedrooms.
