Product description





How does the LWR01 differ from traditional motion sensors?
The LWR01 uses mmWave Radar Technology to detect both movement and stillness (e.g., sitting still, reading), ensuring true human presence detection up to 3.5m. Traditional motion sensors only react to motion.
Does it work with non-Matter ecosystem? What are the compatible smart home hub?
No, it requires a Matter hub with Thread Border Router, such as Apple TV 4K (3rd gen 128GB), Echo (4th gen), Nest Hub (2nd gen), SmartThings Hub v3, or Home Assistant Yellow. Contact our CS to verify support for unlisted devices.
How do I adjust the brightness sensitivity threshold that triggers my smart lights?
You can easily adjust this via the Lafaer Tool App, allowing you to set the brightness level required for your smart lights to turn on/off.
Note: Smart lights and a smart home hub are required for automation.
Where should I install the sensor for optimal performance?
Mount 1.5-2m (4.9-6.5ft) high, facing the center of the detection area. Avoid thick walls/metal obstructions, which block mmWave signals. Maintain clear line of sight for both movement (6m) and presence (3.5m) detection zones.
