Features & Functions

1. Dual-Wiring Compatibility

· Neutral-Live Wire Mode: Requires connection to L (live wire) + N (neutral wire) + light control wire. Provides stable power supply without flickering, supports full load range from 3W to 2000W, ideal for new home installations.

· Single-Live-Wire Mode: Connect only L (Live Wire) + Lighting Control Wire. No neutral wire required. Directly replaces traditional switches, ideal for renovations. Optimized low-load drive supports minimum 3W LED without ghosting.

· Universal Design: Automatically detects wiring configuration on the same panel. No manual switching needed. Zero-threshold installation.

2. Basic Control & Interaction

· Concave Touch: 4mm tempered glass concave capacitive touch supports single tap/long press/double tap with 3ms ultra-fast response. Features backlighting and haptic feedback for non-glare nighttime operation.

· WiFi Direct Connect: 2.4GHz WiFi (dual-band in some models) requires no gateway. Remote on/off and real-time status sync via app (Tuya/Smart Life).

· Voice Control: Native compatibility with Alexa and Google Home; partial support for HomeKit (bridge required). Voice-activated switching, dimming, and scene triggering.

3. Energy Efficiency & Smart Scenes

· Scene Automation: Customize "Arrival/Departure/Sleep/Movie" sequences. 20+ scene groups are supported by one-touch coordination of lighting, curtains, air conditioning, etc.

· Scheduling/Delay: Random lighting when away to simulate occupancy, countdown/repeat scheduling, and automatic on/off by time/sunrise-sunset.

· Energy Management: Standby power < 2W and power/energy consumption tracking encourage energy conservation.

4. Installation & Safety

· European Standard: 86×86mm, compatible with EU flush-mount boxes. Ultra-thin body (≤35mm) flush-mounted without protrusion.

· Load Specifications: AC 230V±10%, compatible with LED, incandescent bulbs, fans, and small appliances.

· Safety Certifications: Flame-retardant PC/ABS construction. Overload, overheat, and surge protection built-in.

· OTA Updates: Remote firmware upgrades for continuous feature optimization and stability.

Application Scenarios

1. Homes for Residents

Smart retrofits for older homes: Neutral wires are not necessary for installation. One-touch switches allow voice control, remote dimming, and sleep mode (one-touch dimming + fresh air) in living areas, bedrooms, and kitchens.

New home whole-home smart systems: Zero-wire wiring provides guaranteed stability. Features timed dimming in children's rooms, dual voice/touch controls for senior safety, and entryway "Home Mode" synchronization.

Safety and energy efficiency: Sensor-activated illumination for night paths, remote power shutoff when away to prevent hazards, and consumption monitoring.

2. Vacation Rentals and Hotels

Guest Room Control: "Do Not Disturb / Housekeeping" status indicators enhance visitor experience; lights, drapes, and air conditioning can be operated via unified control.

Energy Management: Scheduled public area illumination lowers operating overheads; keycard-activated disconnection shuts off power automatically upon departure.

Custom Scenarios: Tailor guest environments effortlessly with dedicated presets like "Work Mode" for executive suites or "Leisure Mode" for vacation rooms.

3. Commercial, Office & Meeting Rooms

Grouped Control: Multi-panel grouped control for zone lighting optimizes operational workflows; rapid switching between "Meeting", "Projection", and "Cleaning" modes.

Retail & Showrooms: Motion-activated scenes improve presentation effects while scheduled on/off schedules eliminate manual intervention across showrooms.

Corridor & Lobby Sensors: Automated sensor setups strike the right balance between continuous public safety and energy reduction.
