Multiple control options: local manual control, app control, and voice control for flexible operation from anywhere. Advanced automation: timer, schedule, and countdown functions let you automate daily routines and energy usage without complex setup. Flexible switching: supports upgrading to dual way control without rewiring and offers three selectable switch types to match your existing switches. Reliable behavior: configurable status memory and interlock functions prevent unwanted states and ensure predictable operation after power loss. Integration ready: group control, family sharing, and linkage with other switch modules, sensors, and appliances enable custom scenes like sleep, work, or away modes. Main functions App remote control: compatible with Smart Life and Tuya Smart apps for smartphone and tablet control anywhere. Voice control: works with voice assistants for hands operation. Timer, schedule, and countdown: create recurring schedules, set timed on/off events, or use countdown timers for automatic shutoff.
