No need for voice control: Relying on physical radar sensing, no need for voice commands, simplifying operation, improving user experience, and making operation intuitive and convenient. TWO wiring methods: Support Neutral Wire system and No Neutral Wire system.Support single fire system,but you need a capacitor when you use No Neutral Wire ystem. APP Remote Control: Download smart life /Tuya smart APP on your phone&Tablet to control the switch anywhere/anytime. High cost-effectiveness and integrated functionality: With just one Tuya Tuya ZigBee radar switch, it can replace the traditional combination of switch and infrared sensor, simplifying the layout of smart homes. Precise detection with 10G millimeter wave radar: Adopting 10G high-frequency radar technology, with a detection range of 6 meters and 100 wide-angle coverage, it can quickly perceive the presence or movements of the human body, suitable for multiple scenarios such as bedrooms, corridors, warehouses, etc. ZigBee Version: Tuya ZigBee Gateway/Hub is required. Supports three modes: Default on, default off, memory function: restores the state before power failure, no need to reset. 19th sensitivity adjustment: Through millimeter wave algorithm optimization, it supports 19 levels of sensitivity adjustment, adapts to different environments, reduces accidental touches, and provides a more accurate experience. Intelligent energy-saving: Automatically adjust the switch status according to the environment and personnel activities, automatically turn off the power when is around, reduce energy waste, and lower electricity costs. Security : Automatic night lighting to avoid searching for switches in the dark and reduce the risk of falls, especially suitable for the elderly and children. Ultra long delay function: Supports up to 8 hours of delayed closing/opening, suitable for short-term stays and long-term usage needs, ensuring flexibility in both and work. Group control: One click control of multiple devices, convenient for setting "sleep mode" (turning off lights and sockets). Offline alarm: When the device malfunctions, the APP push a reminder and support remote restart. Device sharing: Supports up to 5 family members to share devices and independently set operational permissions APP: Smart Life Voltage: AC110-240V 50/60Hz Radar sensing angle: 100 Radar sensing distance: 6m Working temperature: 0 -40 Power: 7-500W/per channel (single live wire), 0-700W/per channel (neutral live wire) Wireless frequency: ZigBee 3.0 Size: 8.6x8.6x3.86cm 1.
