THIRDREALITY Presence Sensor R2,24GHz mmWave Radar,Adjustable Sensitivity,Zigbee Hub Required,Battery Powered,Support Home Assistant,SmartThings,Homey or Echo Devices with Built-in Zigbee hub

Features

• Advanced 24GHz mmWave Radar Detection: Based on advanced 24 GHz mmWave radar technology, it can stably detect through non-metallic materials such as wood and glass. Unaffected by light, temperature, or humidity changes, it delivers consistent performance day and night, while also offering far better user privacy protection than camera-based solutions.
• Battery Powered, Flexible Placement: Powered by 3 standard AA batteries, it completely eliminates the need for power outlets or complex wiring. Whether in a cabinet, bathroom, hallway, or storage room, installation is hassle-free with no power outlet required, truly allowing you to "place it anywhere you want."
• Fast, Stable Zigbee 3.0 Connection: Equipped with low-power Zigbee 3.0 technology, it seamlessly integrates with Home Assistant(ZHA or Z2M), SmartThings (2015/2018), Aeotec, Homey Bridge, Homey Pro and Echo devices with built-in Zigbee hubsincluding Echo (4th Gen), Echo Plus (1st & 2nd Gen), Echo Studio, Echo Show 8 (3rd Gen), Echo Show 10 (2nd & 3rd Gen), Echo Hub, Eero 6, and Eero Pro 6.
• AI-Enhanced Stable Detection: Built with AI-enhanced environment learning, the sensor adapts to your space to reduce false triggers caused by everyday environmental movementsuch as airflow from air conditioning or slight movement of sheer curtainsso it focuses on what matters: real human presence. Note: strong or repetitive motion (e.g., fans) may still trigger detection.
• Adjustable Sensitivity: Adapted to diverse home environments, users can freely switch between 5 sensitivity levels according to actual needs. For example, select High Sensitivity mode to detect subtle movements like adjusting posture or making small gestures, ensuring no missed presence detection. In areas like hallways, select Low Sensitivity mode to focus on significant movement and effectively reduce false triggers.
• Home Automation Ready: This sensor serves as a reliable trigger for your smart home ecosystem.When human presence is detected or no longer detected, it triggers automations across compatible devicessuch as turning on lights, adjusting thermostats, opening or closing curtains, activating security cameras, or sending alerts to your phone.
