24GHz vs 5.8GHz: Why 24GHz Millimeter Wave Radar Wins
🔬 Millimeter-Level Presence Sensing
Breaks through the 5.8GHz limitation of detecting only large movements. Our 24GHz mmWave radar precisely captures micro-motions like human breathing and heartbeat. Whether you're reading quietly or sleeping peacefully, lights stay on intelligently — truly achieving "lights on when present, no false-offs when still."
🛡️ Clean Frequency Band, Zero Interference
Operates on the independent 24GHz frequency band, far from crowded 2.4G/5G WiFi, Bluetooth, and Zigbee signals. Remains stable and reliable in complex electromagnetic environments — no more false triggers or missed detections.
⚡ Ultra-Low Power, Maximum Efficiency
DC 5V powered with ultra-low consumption design. 1 kWh lasts approximately 10,000 hours (~416 days), significantly reducing energy costs. Perfect for battery-powered deployments.
📡 Wide Coverage, One Device Per Room
>90° ultra-wide detection angle + 6-meter range coverage — one sensor handles the entire room. Living room, bedroom, or meeting room, fewer devices needed, lower installation costs.
⚠️ Important Notes
1. App Compatibility
This device uses the Tuya smart platform. Please connect and configure using the Smart Life or Tuya Smart app.
Not compatible with third-party open-source platforms such as ZHA or Zigbee2MQTT. Thank you for your understanding.
2. Zigbee Version — Gateway Required
If you purchased the Zigbee version, a Tuya Gateway or Tuya Multi-Mode Gateway is required for operation.
⚡ The Zigbee version cannot connect directly to your router. Please ensure you have a compatible gateway.
3. WiFi Version — Connection Troubleshooting
Phone detects the device but pairing fails?
This is usually caused by the router failing to assign an IP address.
Solution: Restart your router, then attempt pairing again.

It arrived properly. The accuracy of the automation that turns on the light when a person is detected was good. I thought the detection was a bit slow when the person leaves.

It's easy to set up and the sensing response is good, so it's very useful. When it responds incorrectly, it worked well when I opened the "more" screen in the settings after leaving the room and let it learn.
