Sonoff SenseGuard Presence Core 24GHz Zigbee Human Presence Sensor (SNZB-06P24)
Intelligent Human Presence Detection That Goes Beyond Motion Sensors
Traditional PIR motion sensors only detect movement. Stop moving for a few minutes and your lights may switch off even though you’re still in the room.
The Sonoff SNZB-06P24 SenseGuard Presence Core solves this problem using advanced 24GHz mmWave radar technology, allowing it to detect human presence rather than simply motion. Even subtle movements such as typing, reading, working at a desk, or watching television can be detected, helping your smart home respond naturally to real occupancy.
Whether you’re building a sophisticated Home Assistant installation or simply want lighting that behaves more intelligently, the SNZB-06P24 delivers fast, reliable, and highly configurable presence detection.
True Human Presence Detection
Unlike conventional PIR sensors that rely on body heat and movement, the SNZB-06P24 continuously monitors its environment using 24GHz millimetre-wave (mmWave) radar.
This allows it to:
- Detect people who remain seated or relatively still
- Keep lights on while rooms are occupied
- Reduce false “vacant room” events
- Improve automation reliability
- Create a more natural smart home experience
Ideal for locations where occupants often remain stationary.
Perfect for Smart Lighting Automation
Create lighting that responds naturally to how people actually use a room.
Perfect for:
- Home offices
- Living rooms
- Bedrooms
- Bathrooms
- Kitchens
- Studies
- Meeting rooms
- Hallways
Lights can automatically switch on when someone enters and remain on while the room is occupied even with very little movement.
7 Fully Configurable Detection Zones
Unlike many presence sensors, the SenseGuard allows you to divide the monitored area into seven independent detection zones.
Benefits include:
- Ignore unwanted areas
- Focus detection where people actually are
- Reduce unwanted triggers
- Fine-tune automations
- Improve accuracy for complex room layouts
Each zone can be individually enabled or disabled through compatible Zigbee platforms.
Self-Learning Anti-Interference Technology
Moving curtains, ceiling fans, air conditioners, or other household appliances can cause unreliable automations with some sensors.
The SNZB-06P24 features intelligent self-learning calibration designed to minimise false detections by adapting to its installation environment.
The result is:
- Improved stability
- Fewer false triggers
- More reliable automations
- Better long-term performance
Built-in Ambient Light Sensor
Smarter automations require more than occupancy information.
The integrated light sensor allows you to create intelligent rules such as:
- Turn lights on only when someone is present and it’s dark
- Keep blinds open during daylight
- Activate evening scenes automatically
- Reduce unnecessary electricity usage
By combining presence and brightness data, your automations become significantly more intelligent.
Flexible Installation
Install the sensor wherever it works best.
The included magnetic mounting system features:
- 360° adjustable head
- Wall mounting
- Ceiling mounting
- Shelf placement
- Desktop installation
- Concealed or embedded installation options
This flexibility makes it easy to optimise radar coverage for virtually any room.
Zigbee 3.0 Smart Home Compatibility
The SNZB-06P24 supports the Zigbee 3.0 standard for reliable, low-power communication.
Compatible with:
- Home Assistant (ZHA)
- Zigbee2MQTT
- SONOFF Zigbee Bridge
- Other Zigbee 3.0 coordinators
A compatible Zigbee hub or coordinator is required.
Ideal Automations
Use the SNZB-06P24 to create smarter routines, including:
- Keep office lights on while you’re working
- Turn bathroom lighting off only after the room is truly empty
- Activate bedside lighting when someone gets up during the night
- Control HVAC based on room occupancy
- Pause media when a room becomes vacant
- Trigger security or occupancy notifications
Because the sensor detects presence rather than just motion, automations feel far more natural and dependable.
