The same hardware supports relay, active, and passive outputs with 5 switchable control modes via APP, reducing SKU count and inventory complexity.

All-in-One Load Compatibility
Works with AC three-wire tubular motors, DC low-voltage motors (with control boxes), and lighting loads—covering both shading and lighting applications in a single device.
Retrofit-Friendly with Wired Input Support
Compatible with toggle and reset switches, allowing seamless integration into traditional wiring setups—ideal for retrofit projects.
Smart Life App for easy setup, remote control, device management, and daily operation.
Compatible with AC three-wire tubular motors, DC low-voltage motors with control boxes, and lighting loads, covering curtains, roller blinds, venetian blinds, and lighting control.
One device supports relay, active, and passive outputs, with 5 switchable control modes via app to reduce SKU complexity and inventory pressure.
Supports up/down interlock logic and Stop control for safer curtain operation, while staying compatible with toggle and momentary wired switches for both new and retrofit projects.
