Sonoff SenseGuard Presence Core vs SONOFF Zigbee Human Presence Sensor

Presence and absence events drive scenes and notifications, with a configurable occupancy timeout before the room is reported empty.

5.8GHz Microwave Radar

Zigbee 3.0 (IEEE 802.15.4) end device with an open-area range of 100m. It needs a Zigbee coordinator: a SONOFF gateway, or any Zigbee 3.0 hub such as a Zigbee2MQTT or ZHA dongle.

Presence and the lux reading can both trigger eWeLink scenes, which is how SONOFF pitches it for lighting that only turns on when the room is dark and occupied.

eWeLink keeps occupancy detection logs and a record of the light level over time, which SONOFF also allows exporting.

The radar answers occupied or not occupied. SONOFF never claims people counting, and Zigbee2MQTT exposes a single occupancy binary rather than per-target data.

SONOFF states the device cannot accurately detect a sleeping person, because the chest movement of breathing during sleep is too subtle for it.

SONOFF lists Alexa among the third-party platforms that can query the motion status, through the eWeLink cloud-to-cloud integration behind a SONOFF Zigbee gateway.

The sensor has no HomeKit profile of its own. SONOFF documents Apple Home support through its own Matter bridges (ZBBridge-U, iHost, eWeLink CUBE), which republish the Zigbee device into the Apple ecosystem.

SONOFF lists this model among the Zigbee devices its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) publish to Matter, which is how it reaches the Apple Home app. Apple Home has no Zigbee radio of its own.

SONOFF lists Google Home among the third-party platforms that can query the occupancy status, once the sensor is added to eWeLink through a SONOFF Zigbee gateway and synced cloud to cloud.

Zigbee2MQTT supports the exact model and exposes occupancy, illuminance, the occupancy timeout, radar sensitivity, the seven detection zones and the spatial learning calibration. SONOFF also documents ZHA, which currently needs a quirk script it provides.

The device is Zigbee, not Matter. SONOFF's own Matter bridges (ZBBridge-U, iHost, eWeLink CUBE) are what expose it to a Matter fabric.

The device is not Matter itself: SONOFF lists it among the Zigbee models its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) republish into Matter.

SONOFF publishes a SmartThings driver for the model and links the channel invite from its help center page; the device then reports occupancy in SmartThings.

Permanently powered over a USB-C port rated 5V 0.5A. There is no battery option, so the sensor has to stay plugged in.

Ambient light sensor reporting a lux value, with a calibration offset and a history log. Zigbee2MQTT exposes illuminance and the illuminance calibration.

24GHz mmWave radar that reads micro-movements such as the chest expansion of breathing, so it holds detection on someone sitting still. SONOFF notes a completely motionless person is best detected within 3 meters facing the device, and that it cannot reliably detect a sleeping person.
