Product detailed description

〰️ Sonoff SenseGuard Presence Core 24G – mmWave Presence Sensor

Sonoff SNZB-06P24 accurately detects even the subtlest human micro-movements thanks to advanced 24GHz mmWave radar technology. This ensures stable presence detection whether you are working, reading, or simply sitting quietly.

📝 Note: The device cannot reliably detect a sleeping person, as breathing during sleep produces only extremely subtle chest movements.

Radar technology with a 24 GHz frequency provides a detection range of up to 4 meters and a 110° viewing angle. The detection area can be divided into seven independently configurable zones, each of which can be turned on or off. This allows the sensor to monitor only relevant parts of the room and exclude zones where presence detection is not needed.

Thanks to the built-in self-learning anti-interference system, the SNZB-06P24 sensor automatically detects and filters out moving sources of interference, such as household appliances, fans, and air conditioners. This effectively reduces the risk of false alarms during normal household operations. 

Thanks to the built-in light sensor, it can also measure ambient light levels. This enables smart automations – for example, automatically turning on lights only when someone is in the room and the brightness drops below a set threshold (e.g., at twilight), helping to reduce unnecessary energy consumption while enhancing convenience and comfort. Furthermore, added calibration and history logging accurately track lighting changes in your home environment for perfectly precise control.

The sensor utilizes Zigbee 3.0 communication, making it compatible with Home Assistant, SmartThings, Alexa, eWeLink, and other Zigbee-supported platforms. When using third-party Zigbee platforms, advanced settings can be configured via Bluetooth using the eWeLink app, as all settings are stored locally on the device.

📝 Note: This device also acts as a Zigbee router, helping to extend Zigbee network coverage.

You can easily connect all Sonoff Zigbee devices to the Apple Home ecosystem via a Matter Bridge, enabling seamless and convenient control.

• Apple Home support (via Matter Bridge): Supported gateways include ZBBridge-U, iHost, or Cube OS using a SONOFF Zigbee Dongle.

• Integration with third-party platforms: Requires adding the device to the eWeLink app via a SONOFF Zigbee gateway and syncing it via cloud-to-cloud integration.

The compact SNZB-06P24 sensor offers versatile installation options. Featuring a strong magnetic base and a 360° rotatable head, you can easily point it directly at the desired area.

You can place it freestanding on a desk or shelf, or easily mount it on a wall or ceiling. For mounting, you can use the included double-sided adhesive tape or mounting screws. If you prefer a clean, minimalist design, an optional frame allows you to install it flush into the ceiling.
