Monitor rooms with reliable, wireless detection. The sensor combines 24 GHz mmWave radar and PIR to recognize both large movements and micro-movements (static presence). From the Tuya / Smart Life app you can adjust distance and sensitivity , receive real-time alerts and create scenes (turn on lights, activate ventilation, security mode). It can be installed in just a few minutes with a 360° rotatable base and is Zigbee , therefore it can be integrated with Home Assistant via Zigbee2MQTT/ZHA (requires Zigbee hub) .
The Smart mmWave + PIR Presence Detector protects your home with precise motion detection and real-time push notifications on Tuya or Smart Life . Ideal for entryways, living rooms, and hallways, it offers automatic day/night scenarios , event logs , and support for Alexa and Google for voice automation. Intelligent and discreet security, wall-mounted in minutes.
The sensor allows you to precisely calibrate its response: you can set the mmWave radar detection distance , adjust the sensitivity to motion and the sensitivity to static motion . This way you adapt the range to the room, limit false alarms and obtain detection truly tailored to your environment.
The sensor uses 24GHz radar , which offers high micro-motion resolution and strong penetration capability , with a lower false alarm rate than 5.8GHz and more smart home- friendly operation than 77GHz. This translates into precise presence recognition, stable response even in complex scenarios, and reliability for home and security automation.
Manage the Presence Detector from the Tuya or Smart Life app: adjust distance and sensitivity with sliders, check the status , create SE/POI automations and save scenes for each room (living room, bedroom, hallway). The device is Zigbee and integrates with Home Assistant via Zigbee2MQTT or ZHA (requires a compatible Zigbee hub/gateway) , so you can use it in advanced workflows, notifications and multi-device scenarios. Clear control even remotely, with notifications and event logs.
The sensor features a quick-release mounting plate and a 360° rotatable base : simply place it on a wall or ceiling , adjust the angle in seconds, and reposition it when needed, without tools. The modular structure ensures a clean installation and precise targeting of the area to be monitored.
The sensor is perfect for multiple environments: entrances and offices , hallways and bathrooms . With the Tuya or Smart Life app—or with Home Assistant via Zigbee—you can create automatic scenes in just a few taps. Simple automations that reduce consumption and improve comfort and safety, activating lights, ventilation, and air conditioning only when someone is actually present. Practical examples:
This sensor communicates via Zigbee and requires a Zigbee gateway or hub to connect to the Tuya / Smart Life app. The 2.4 GHz home Wi-Fi network is only needed for the hub and your smartphone: without a Zigbee hub , the sensor cannot be added, controlled, or automated. Choose a compatible Tuya Zigbee gateway and then pair it from the app.
The sensor detects human presence even without obvious movement thanks to mmWave radar : while you put on makeup, read, or work at your desk, the lights and climate control remain on and turn off only after the set timeout . The static sensitivity is adjustable, so you avoid unwanted shutdowns and have more reliable automations in the bathroom, bedroom, study, or changing room.
The sensor distinguishes motion and static presence (mmWave + PIR) via app.
From the app you can view the chronological list of recorded entries/exits and attendance.
Enjoy wireless installation and minimal maintenance: the sensor lasts >240 days thanks to ultra-low power consumption. Uses 2 replaceable AAA batteries (not included).
Yes. The sensor communicates via Zigbee and requires a compatible Zigbee gateway/hub to connect to the Tuya / Smart Life app (or Home Assistant via ZHA/Zigbee2MQTT).
No, it uses 2 AAA batteries (not included). With typical use, battery life is over 240 days . Get low battery alerts in the app.
Yes. The 24 GHz mmWave radar detects static presence (micro-movements), while the PIR detects more obvious movements.
It mounts on the wall or ceiling with a quick release plate and a 360° rotatable base to aim the area to be monitored.
You can receive presence/absence push notifications , record event logs , and use it as a trigger for scenes (lights, climate, siren, cameras).
