Sonoff Zigbee SenseGuard Presense Core 24G

Smarter Presence Detection for a More Responsive Smart Home

Stop relying on basic motion sensors that can switch your lights off while you're still sitting, reading, working, or relaxing.

The SONOFF SenseGuard Presence Core 24G (SNZB-06P24) is an advanced 24GHz mmWave Zigbee human presence sensor designed to detect both movement and subtle human activity. Its radar technology helps your smart home recognise when a person is still present, making everyday automations more reliable and practical.

✔ Advanced 24GHz mmWave Presence Detection
✔ 7 Customizable Detection Zones
✔ Up to 4m Detection Range with 110° FOV
✔ Self-Learning Interference Calibration
✔ Built-In Ambient Light Sensing
✔ Zigbee 3.0 + Bluetooth Configuration
✔ Home Assistant & Compatible Smart-Home Integration
✔ Flexible Magnetic Mounting Design

Built for smart lighting, occupancy detection, Home Assistant setups, offices, bedrooms, living rooms, and modern Zigbee smart homes.

Presence Detection That Understands More Than Movement

Traditional motion sensors are effective when someone is walking around, but they can struggle when a person remains relatively still.

The SONOFF SNZB-06P24 uses advanced 24GHz mmWave radar to detect larger movements as well as subtle human movements, including small movements during everyday activities. This helps keep presence-based automations active when someone is sitting quietly, reading, typing, or working.

The result is a smarter way to automate your home—using actual presence rather than relying only on obvious movement.

Important: The sensor cannot reliably detect a sleeping person because breathing movements during sleep can be extremely subtle. For a completely still person, detection works best within approximately 3 metres directly facing the device.

Why Choose the SONOFF SenseGuard Presence Core 24G?

Choosing a Zigbee presence sensor is about more than simply detecting movement. Detection accuracy, interference management, coverage, automation flexibility, and smart-home compatibility all matter.

The SNZB-06P24 combines:

24GHz mmWave radar for more sensitive human presence detection

7 configurable detection zones for precise coverage control

Self-learning Detection Calibration to help filter fixed interference sources

Ambient light sensing for smarter lighting automation

Zigbee 3.0 connectivity for integration with compatible smart-home systems

Bluetooth configuration for supported advanced settings

Flexible magnetic mounting for convenient positioning

Every feature is designed to give you greater control over how presence detection works within your space.

Why the SNZB-06P24 Compared to Standard Motion Sensors

The Difference You Notice Immediately

Keep Lights On While You're Still There

The 24GHz mmWave radar can detect subtle human movements during activities such as reading, typing, working, or sitting.

This helps prevent your smart lights from switching off simply because you have stopped moving around the room.

Control Exactly Where Presence Is Detected

The sensor divides its detection area into 7 independent zones that can be individually enabled or disabled.

Use zone configuration to focus detection on the areas that matter while excluding unwanted areas such as doorways or other potential trigger zones.

Reduce Unwanted Triggers

Detection Calibration allows the sensor to learn fixed-position interference sources and filter them from detection.

This can help manage interference from common household sources such as appliances, water pipes, and other fixed objects within the sensing area.

Build Smarter Lighting Automation

The built-in ambient light sensor adds brightness information to your automations.

For example, your smart-home system can be configured to activate lighting when human presence is detected and the surrounding light level is low.

Extend Your Zigbee Network

The SNZB-06P24 can also act as a Zigbee router, helping extend Zigbee network coverage within a compatible Zigbee setup.

Position It Where You Need It

The magnetic base and adjustable head support desktop placement, wall mounting, ceiling installation, and other suitable mounting configurations.

This gives you greater flexibility when positioning the sensor for the best detection coverage.

How to Use the SONOFF SNZB-06P24

Using the SONOFF Zigbee presence sensor is straightforward:

1. Choose the installation position.
Place the sensor where it has a clear view of the area you want to monitor.

2. Connect a compatible Zigbee gateway or coordinator.
A Zigbee hub is required. The SNZB-06P24 is not a standalone Wi-Fi sensor.

3. Add the sensor to your smart-home system.
Pair it with a compatible SONOFF Zigbee gateway or supported third-party Zigbee setup.

4. Configure your detection area.
Use supported eWeLink/Bluetooth configuration tools to adjust available detection settings and the 7 detection zones.

5. Run Detection Calibration when required.
Allow the sensor to learn fixed-position interference sources within the detection area.

6. Create your smart automations.
Use human presence and ambient light information to control compatible lights, switches, appliances, and other smart-home devices.

7. Fine-tune the sensor position.
Adjust the sensor head and installation position to achieve the desired detection coverage.

Who Is It For?

The SONOFF SenseGuard Presence Core 24G is ideal for:

Smart-home enthusiasts
Build more responsive occupancy-based automations throughout your home.

Home Assistant users
Integrate the sensor into supported Home Assistant setups using compatible SONOFF Zigbee hardware.

Smart lighting users
Create lighting automations that respond to both human presence and ambient brightness.

Home-office users
Keep lighting active while working, reading, typing, or sitting with minimal movement.

Zigbee users
Expand an existing Zigbee network with an advanced human presence sensor.

Homeowners upgrading from motion sensors
Improve presence-based automation where conventional motion detection switches lights off too quickly.

Automation-focused households
Create more precise room occupancy scenes using configurable detection zones.

If your smart home currently reacts only when someone moves, the SNZB-06P24 gives you another level of control by adding more sensitive presence detection.

Compatibility & Setup Information
