SONOFF Human Presence Sensor: SenseGuard Presence Core SNWF-06P24

The SONOFF SenseGuard Presence Core 24GHz Matter over Wi-Fi human presence sensor (part SNWF-06P24) is a wired 5V DC 24GHz radar presence detector that pairs over Matter via Wi-Fi and is CSA-certified for Matter 1.5. MatterCheck's type-level matrix for motion/occupancy sensors lists pairing and control support as Yes on Apple Home, Google Home, Amazon Alexa, SmartThings, Home Assistant, Homey, and Hubitat. SONOFF's product page specifically names Apple Home and SmartThings, and describes Home Assistant integration via MQTT Discovery and WebSocket/MQTT/Open APIs.

SONOFF SenseGuard Presence Core SNWF-06P24 transport and certification

This model uses Matter over Wi-Fi on IEEE 802.11 b/g/n 2.4GHz and is not a Thread device, so it does not require a Thread border router. The CSA certification record lists transport as Wi-Fi and Bluetooth and the specification version as Matter 1.5. CSA certificate CSA264MAMAT55394-24 has certified date 09/01/2026, vendor ID 0x1321 (4897 decimal), product ID 0x0154 (340 decimal), firmware v1.0, hardware v1.0, and primary device type ID 0x0107. The DCL model record has part number SNWF-06P24 and deviceTypeId 263, which maps to MatterCheck's motion/occupancy device type.

Per-platform Matter support for SONOFF SNWF-06P24

These are MatterCheck's type-level matrix answers for the motion/occupancy device type, not a product-specific hands-on test. No dated product-specific platform review is present in the sources used here. For generic platform support notes, see MatterCheck's Matter motion sensor support guide.

SONOFF's product page specifically names Apple Home and SmartThings for Matter pairing, and says Home Assistant and openHAB can be connected via WebSocket, MQTT, and Open APIs. SONOFF's Matter Home Assistant guide describes adding Wi-Fi-based SONOFF Matter devices to Home Assistant via the Matter integration (worked example: M5 Matter); SNWF-06P24 appears in the site's product navigation but not in the guide's supported Matter device list. The product page also states Apple ecosystem support for Siri, iPhone, iPad, and Apple Watch.

Cross-platform comparison for SONOFF SNWF-06P24

Across all seven platforms, MatterCheck's motion/occupancy matrix gives the same split: Yes for pairing, control, and starting automations, and No for being controlled by automations. MatterCheck's type-level matrix rates the motion/occupancy device type as able to start automations on all seven platforms; this has not been verified for SNWF-06P24 specifically. SONOFF's marketing copy is narrower for Matter in naming Apple Home and SmartThings, while Home Assistant is described through MQTT Discovery and local APIs. SONOFF's Matter guide also supports Matter multi-admin for sharing a SONOFF Matter device with multiple controllers, including Home Assistant, Alexa, or Google Home.

Setup in Home Assistant and other SONOFF Matter platforms

SONOFF's Matter Home Assistant guide provides a general Matter-over-Wi-Fi commissioning walkthrough (illustrated with M5 Matter): open the Home Assistant app, go to Settings > Devices & Services, select Add Integration, search for Matter, choose Add Matter device, select No, it's new, then scan the device's Matter QR code or enter the setup code and tap Add to "Home Assistant"; it does not publish SNWF-06P24-specific steps. The guide states that Wi-Fi-based SONOFF Matter devices (its examples are MINIR4M and M5 Matter) connect directly to a 2.4GHz Wi-Fi network and do not need a Thread border router.

For local Home Assistant use outside Matter, SONOFF's product page says it supports Home Assistant integration via MQTT Discovery for real-time data and automations. SONOFF also mentions openHAB support through WebSocket, MQTT, and Open APIs.

SNWF-06P24 specs, detection limits, and calibration

Manufacturer-listed specifications from SONOFF's product page:

• Power: 5V DC 1A input via USB Type-C; no battery. It is not battery-powered.
• Radar: 24GHz FMCW radar with detection range up to 4 meters and 7 configurable zones.
• Wi-Fi: IEEE 802.11 b/g/n 2.4GHz; MCU ESP32-C6.
• Size and weight: 44.2 × 44.2 × 59 mm; 34.5 g; PC+ABS casing; indoor use only.
• Environment: -10℃ to 60℃; 0–90% RH non-condensing; below 2000m altitude.
• Light sensing: ambient light monitoring and illuminance logging for daylight/dusk/night lighting automation.
• Local tools: browser-based OpenEdge local web console for OTA updates, light calibration, logs, and zone/environment settings.
• Price: $24.90 on SONOFF's product page.

SONOFF's detection and calibration statements:

• The 24GHz radar can detect subtle human movements such as chest expansion during breathing, but SONOFF says it cannot reliably detect a sleeping person.
• For a completely still person, detection works optimally within 3 meters and directly facing the device.
• Detection Calibration learns and filters fixed-position interference sources such as appliances, water pipes, and large metal surfaces; it cannot filter moving interference like pets or robot vacuums.
• If an interference source changes position, Detection Calibration must be rerun.
• Brightness readings can vary with sensor orientation; SONOFF says to fix orientation and use the brightness calibration function.

No independent reviewer hands-on report is included in the provided sources; the performance and limitation statements above are manufacturer claims.

SONOFF SNWF-06P24 pairing and not-responding fixes

SONOFF's Matter Home Assistant guide includes troubleshooting that applies to Matter Wi-Fi devices. If the device is not found during pairing, check that it is in pairing mode (LED blinking rapidly), confirm it is on the same 2.4GHz Wi-Fi network as Home Assistant, and reboot the router and Home Assistant if necessary. If Matter Server is not working, ensure the Matter add-on is started and restart Home Assistant Core. If a paired device stops responding, SONOFF says to check the IP address and Wi-Fi strength, then restart or re-pair the sensor. The product page also says to follow the Installation Guide and avoid improper mounting locations to improve detection accuracy. For additional checks, see MatterCheck's Matter device not pairing guide.

SONOFF SenseGuard Presence Core SNWF-06P24 verdict

• Buy if you want a wired 5V DC powered Matter over Wi-Fi presence sensor with 24GHz radar, 7-zone detection, ambient light logging, and no Thread border router requirement, and you use Apple Home, SmartThings, or Home Assistant via Matter/MQTT.
• Skip if you need reliable sleeping-person detection, battery power, or filtering of moving pet or robot-vacuum interference; SONOFF states it cannot reliably detect sleeping people and cannot filter moving pet or robot vacuum interference.
