Empowering Smart Homes with Stability, Simplicity and Elegance
1. Overview
Leondarx PLC Smart Switch System adopts Power Line Carrier (PLC) technology to transmit control signals directly through existing electrical wiring, eliminating the need for additional signal cables.
It provides a stable, interference-resistant, and easily deployable smart home control solution, perfectly suited for villas, apartments, offices, and renovation projects.
With years of engineering practice and over 2,000 successful installations, Leondarx’s PLC system stands out for its zero re-wiring, high stability, and precise real-time control.
2. System Architecture
Leondarx PLC Smart System uses a distributed architecture consisting of:
PLC main controller (central brain)
PLC dimming and relay modules
Multi-function sensors (temperature, illumination, human presence)
Smart switch panels (touch / mechanical hybrid)
Scene and linkage programming
Mobile App or wall-mounted control terminals
Signals travel through existing power lines, achieving room-to-room, floor-to-floor communication without any network delay.
3. Core Functions
✅ Lighting Control – Dimming, zoning, timing, and scene modes for living room, bedrooms, corridors, and outdoor areas.
✅ Environmental Control – HVAC (air-conditioning, heating, ventilation) and curtain automation.
✅ Presence-Based Control – Automatically adjusts lighting and temperature according to human presence and brightness.
✅ Scene Customization – “Home Mode”, “Movie Mode”, “Sleep Mode”, “Away Mode”, and more.
✅ Energy Saving – Automatically shuts off unused circuits, reducing energy consumption.
✅ App & Voice Control – Integrates with smart devices for mobile and voice assistant control.
