Flexible Channel Options
Available in 2/3/4-channel models for independent control of multiple devices, saving space and cost.
True No-Neutral Design
Works stably without a neutral wire—ideal for retrofitting in older homes without rewiring.
No External Capacitor Needed
Built-in optimized circuitry eliminates flickering and ensures compatibility with various LED loads—plug and play.
No-neutral design makes smart upgrades easier for traditional wiring systems.
When connected to a Tuya ZigBee gateway, it enables app control, voice control, and smart scene automation.
Available in 2/3/4 channels, with a compact body designed to fit inside the switch box for multi-circuit lighting control.
