Introduction
Matter Over WiFi Human Presence Sensor
User Manual V1.0
SenseGuard Presence Core 24G is a human presence sensor based on microwave radar technology. It continuously emits microwave signals into the surrounding environment and detects changes in the reflected signals caused by human breathing, enabling accurate presence detection.
Operating at 24GHz, the device offers high precision and can detect even subtle movements. It supports masking of specific detection ranges or interference sources in designated areas, providing strong anti-interference performance. The built-in ambient light sensor enables more flexible and advanced smart scene conditions.
The device helps detect abnormal intrusion or presence and can promptly trigger linked devices such as cameras and alarms for precise security protection. It can also automatically control lights, fans, and other appliances based on human presence, delivering a more convenient and effortless smart living experience.

Installation
Installation
① Step One: Choose a Suitable Installation Location
Common Interference Sources:
1. Moving objects: operating fans, air conditioners, washing machines, swaying curtains or plants, drainage pipes, etc.
2. Metal objects: large metal surfaces, mirrors with metallic coatings etc.
The farther an interference source is from the sensor, the less impact it has on detection. Whenever possible, keep interference sources outside the detection area.
For interference sources that remain within the detection area, the device can reduce false detection through Detection Area Setting (②) and Detection Calibration (④).
*Note: Interference sources with non-fixed positions, such as pets and robot vacuums, cannot be excluded.
② Step Two: Block Interference Zones
On the device settings page, use the Detection Area Setting feature to block detection zones that contain interference sources. Each zone can be enabled or disabled individually.
③ Step Three: Mount the Device
Install the device at a height of 1–2 meters.
For optimal performance, aim the sensor directly toward the human chest area.
Installation Methods:
① Desktop placement.
② Attach the base magnetically to a metal surface.
③ Attach the base using 3M adhesive.
④ Secure the base with screws.
*Note: This device is intended for installation at a height of no more than 2 m.
*Note: Keep multiple sensors apart and avoid facing them toward each other.
*Note: After mounting the sensor, use the included cable clips to secure the power cable and prevent it from moving.
④ Step Four: Eliminate Interference in Unblocked Zones
This feature is mainly used to reduce interference from appliances that operate continuously in a fixed location, such as fans, air conditioners, or washing machines.
Leave the detection area and make sure the appliance you want to exclude remains powered on and operating.
Enable Detection Calibration feature on the device setting page. The device will automatically self-learn the movement pattern of the interference source and exclude it from detection.
Notes for installation:
① If the sensor position or the position of any interference source changes, please reconfigure Detection Area Setting and Detection Calibration as required.
② Some settings (Detection Area Setting and Detection Calibration) may not be available on certain third-party Zigbee gateways. For third-party users, please download the eWeLink App, scan the QR code on the device, and follow the in-app instructions to connect and configure.
③ Interference sources with non-fixed positions, such as pets or robot vacuum cleaners, cannot be blocked or excluded.
Factory Reset
Long press the device button for 10 seconds until the LED indicator quick flashes 5 times. The device will be restored to factory settings.
Power on
After powering on, the device will enter the Pairing Mode during the first use. The LED indicator changes in a cycle of two short and one long flash.
The device will exit pairing mode if it is not paired within 10 minutes. To enter pairing mode again, press and hold the device button for about 5 seconds until the LED indicator flashes twice quickly and once slowly, then release the button.

Web Console Guide
1. Access via AP Hotspot
When the device is in pairing mode, it will automatically enable an AP hotspot.
Connect to the device hotspot SONOFF_SNWF-06P24_xxxx, then enter the following in your browser: 192.168.33.1 to access the Web Console.
2. Access via LAN
After the device is successfully connected to Wi-Fi, ensure your phone or computer is on the same local network. Then enter either: SNWF-06P24.local or the device’s IP address (check it in your router’s admin panel) in your browser to access the Web Console.
Detection Range
Radial detection distance: approximately 4m.
Detection angle: 120°
*Note: In narrow indoor environments, microwave reflections may be stronger, which can result in a wider effective detection angle.
