1. Every Space Has Its Own Light Language
When most people hear "smart lighting," they think of turning on lights with a phone. But for homeowners who have actually lived in a smart-lit luxury flat, the experience goes far beyond that. It's the moment you walk in and the entryway lights automatically brighten to 30%, while the living room main light is already set to your favorite 4000K warm white. It's the middle-of-the-night trip to the bathroom where the corridor floor lights glow at just 10% brightness — enough to see, not enough to wake anyone. It's one tap into "cinema mode" and the spotlights dim, the LED strips turn blue, and the curtains close automatically.
Today we're sharing a real delivery case: a 180㎡ four-bedroom luxury flat with 76 lighting control nodes throughout, designed and deployed in 30 days. The homeowner's verdict: "Since moving in, I never want to touch a wall switch again."
2. Project Background & Core Requirements
Layout: Four bedrooms, two living areas, two bathrooms. North-south facing. Premium finished — no major rewiring allowed.
The homeowner's four core requirements:
1. Independent dimming and color temperature control in every room for different scenarios
2. No complex panels — elderly family members and children must be able to use it easily
3. Automatic night lighting for bathroom trips without disturbing others
4. Controllable energy consumption — target 30%+ reduction in monthly electricity costs
3. Solution: PLC + BLE Mesh Dual-Mode Architecture
The core reason for choosing PLC (Power Line Communication) was zero additional wiring. Signals travel through existing electrical wires — no new signal cables needed. For premium finished homes, this is the most cost-effective and stable solution.
We deployed 1 PLC gateway + 6 BLE Mesh sub-gateways throughout the flat. All 76 lighting control nodes connect wirelessly with response latency under 200ms.

Control Panels
The entire flat uses Xuanniao N01 color-screen smart switches to replace the original wall switches. Each panel supports 8-channel lighting control, one-tap scene switching, and voice commands. Elderly family members don't need to learn an app — just touch the screen or speak.
