Background & Scale

A premium resort hotel in Hangzhou's West Lake district with 500 guest rooms and a year-round occupancy rate above 85% decided to upgrade its lighting experience during its third renovation. Guest rooms relied on a single ceiling light with zero ambiance, and one complaint kept recurring in reviews: "The lights are too hard to turn off — I even switched on the wrong one at midnight."

Pain Points

• Identical lighting for reading, napping and bathing — no ambiance at all;
• Corridors and public areas lit 24/7, with annual electricity costs exceeding ¥1.2 million (~US$170K);
• Faulty lamps required manual room-by-room inspection, averaging 30+ minutes per response and hurting the guest experience.

Solution

After three rounds of on-site survey and solution reviews, a BLE Mesh whole-property smart lighting solution was deployed:

• Guest rooms: 1 smart gateway, 3 smart switch panels, 4 CCT-adjustable spotlights, 6 downlights, 1 curtain motor set and 2 occupancy sensors per room — batch provisioning for fast rollout;
• Public areas: smart controllers and ambient light sensors in the lobby, restaurants, corridors and meeting rooms, auto-dimming by brightness and schedule;
• Management: integrated with the hotel PMS — check-in automatically assigns lighting preferences, while the engineering team monitors everything in real time with second-level fault localization;
• Voice magic: every room ships with a USB voice controller. One phrase — "I'm going to sleep" — turns off the lights, warms the bedside glow, closes the curtains and sets the AC to sleep mode.

Results (First 3 Months of Operation)

Using a floor-by-floor phased rollout, all 500 rooms and public areas were completed in just 45 days without interrupting operations. "Voice-controlled guest rooms" became a marketing highlight, driving significant organic traffic for the hotel.

Background & Layout

A 180㎡ four-bedroom apartment with a north-south through-layout. The owner wanted independent dimming and color tuning in every room, controls simple enough for both elderly parents and kids, undisturbed night-time trips to the bathroom — and a monthly electricity bill cut of 30% or more. The biggest constraint: it was a finished home — no major rewiring allowed.

Solution: PLC + BLE Mesh Dual Mode

PLC was chosen for one core reason — zero new wiring. Signals travel over existing power lines, so not a single signal cable was added. With 1 PLC gateway and 6 BLE Mesh sub-gateways, all 76 lighting control nodes went fully wireless with response latency under 200ms.

• Living room: anti-glare spotlights + RGB strips (18 nodes), scene-linked 16-million-color control;
• Master bedroom: warm-white downlights + bedside reading lights (8 nodes), 2700K fade-to-sleep mode;
• Kids' room: full-spectrum eye-care lights (6 nodes), Ra98 high CRI, study/play modes;
• Kitchen & bath: moisture-proof downlights + sensor strips (10 nodes), mmWave presence activation;
• Entry & hallway: recessed footlights (12 nodes), 10% low-brightness night sensing;
• Balcony: waterproof spotlights + ambient lighting (6 nodes), auto-on at sunset.

Every wall switch was replaced with the Xuanniao N01 color-screen smart switch — each panel supports 8 circuits, one-tap scene switching and voice commands — plus 8 mmWave human presence sensors.

Six life scenes at one tap: Wake-up (simulated sunrise), Reading (5000K/500lux), Cinema (1.5s transition), Night (PIR low-brightness), Away (all-off), and Guest (4000K warm white).

Background & Pain Points

A 12-room boutique guesthouse in Moganshan, where over 200 similar properties compete within a 10km radius and hardware is nearly identical. The owner faced three very real problems:

• Guests couldn't operate the lights: 6 switches per room meant a dozen calls to the front desk every night in peak season asking "which button does what";
• Stubborn energy bills: guests left lights on when going out — monthly electricity topped ¥12,000 in peak season, with roughly 30% of it "paid to empty rooms";
• Homogenized experience: neighbors had smart toilets and projectors, but lighting was flat and white — nobody ever mentioned the lights.

Lightweight Solution: No Renovation, No Ceiling Work

Each guest room received: 2× 4-circuit smart switch panels, 4× smart dimming drivers, 1× mmWave presence sensor and 1× door/window sensor. Public areas got a front-desk scene panel and 3 corridor sensor strip controllers. Everything was installed on existing wiring.

• Welcome mode: warm white 3000K at 80% brightness, strips fading in — "warmth the moment you open the door";
• Sleep mode: say "I'm going to sleep" and only the bedside footlight stays on at 10%;
• Cinema mode: main light off, spotlights at 20%, strips shift to amber for a mountain-starry movie night;
• Reading/work mode: 5000K cool-white reading light for business travelers.

All scene transitions fade smoothly over 3 seconds — no jarring snap-on/snap-off. That smoothness is exactly what guests describe as "premium".

Results

Of 47 new post-retrofit reviews, 22 praised the lighting — and three groups of guests asked "what smart lights do you use? I want a set too." Lighting turned from a cost line into a marketing asset. The solution is now deployed at 10+ guesthouses across Moganshan, Dali and Xiamen, scaling flexibly from 12 to 100 rooms.
