Introduction
Smart Motion Sensor
User Manual V1.0
SNZT-03P is a low-power motion sensor based on Zigbee 3.0 and Matter over Thread protocols, allowing easy integration with multiple ecosystems. With smart scenes, it can be used to automatically turn lights on when people enter and off when they leave hallways, corridors, and other areas. It can also be used for security scenarios such as unauthorized intrusion, triggering cameras to record video, gateways to sound alarms, and app notifications. Enjoy a more flexible and intelligent home automation experience.
