What the differences mean
Detection range and area
The Aqara Presence Sensor FP2 covers a 7 metre radius across a 120 degree angle, up to about 40 square metres, so one unit can watch an open-plan living room. The Sonoff SenseGuard Presence Core reaches about 4 metres radially, which makes it a small-room device.
People counting
The Aqara Presence Sensor FP2 tracks up to five people at once, which matters for an automation that should react to who is where. The Sonoff SenseGuard Presence Core reports only occupied or not occupied, with no per-person data.
Fall and sleep monitoring
The Aqara Presence Sensor FP2 adds fall detection and contactless sleep monitoring, useful for elderly care. The Sonoff SenseGuard Presence Core has neither, and Sonoff states it cannot reliably detect a sleeping person.
Power and mesh role
Both are mains powered over USB-C, but the Sonoff SenseGuard Presence Core repeats the Zigbee mesh while it is permanently powered, whereas the Aqara Presence Sensor FP2 runs over Wi-Fi and does not extend any mesh.
Weather and placement
The Aqara Presence Sensor FP2 is IPX5 rated, so a humid bathroom is inside its specification. The Sonoff SenseGuard Presence Core carries no IP rating and is listed for indoor use only.
How they reach your smart home
The Aqara Presence Sensor FP2 works directly over 2.4 GHz Wi-Fi with Apple HomeKit, Alexa, Google Home, SmartThings and Home Assistant. The Sonoff SenseGuard Presence Core is Zigbee, so it needs a coordinator, with Alexa and Google Home arriving through the eWeLink cloud and SmartThings through a Sonoff driver.
Which one to buy if
- one sensor has to cover a large open-plan room
The Aqara Presence Sensor FP2 reaches 7 metres across 120 degrees and can divide that space into zones.
- you want fall alerts for an elderly relative
Fall detection is exclusive to the Aqara Presence Sensor FP2 of these two.
- the sensor is for a desk, hallway or small room
The Sonoff SenseGuard Presence Core is sized for about 4 metres and costs less to cover that.
- you want the sensor to also extend your Zigbee mesh
It is permanently powered and acts as a Zigbee router, unlike the Wi-Fi Aqara.
- you want native HomeKit or Alexa without a hub
The Aqara Presence Sensor FP2 connects directly over Wi-Fi; the Sonoff needs a Zigbee gateway.

What owners say
Owners of both sensors agree on the core win: lights no longer cut out while someone sits still, which is exactly the failure both were bought to fix, and both groups praise fast, low-latency triggering. After that they diverge. Aqara Presence Sensor FP2 owners love the multi-zone setup that replaces several sensors with one, the multi-person tracking, the light sensor and the fall and sleep features, and they value running on USB-C with no batteries. Their complaints are about tuning: reflective surfaces and moving objects cause ghost detections until the interference zones are mapped, setup is involved and needs an Aqara account, the three modes cannot run at once, and HomeKit reports presence as true or false rather than a count. Sonoff SenseGuard Presence Core owners single out the easy pairing on Zigbee2MQTT or ZHA, the accurate lux reading and the seven maskable zones, while flagging the short 4 metre reach, the sensitivity to fans and appliances after calibration, and the absence of sleep or fall detection.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

Frequently Asked Questions
Which is better overall: Aqara Presence Sensor FP2 or Sonoff SenseGuard Presence Core?
The Aqara Presence Sensor FP2 for coverage, zones, multi-person tracking and fall and sleep monitoring. The Sonoff SenseGuard Presence Core is the better value for a small room on an existing Zigbee network, where its lower price, two-year warranty and wider ecosystem make sense.
What is the biggest difference between the Aqara Presence Sensor FP2 and the Sonoff SenseGuard Presence Core?
Scale. The Aqara Presence Sensor FP2 covers up to 40 square metres, zones the room and tracks up to five people, while the Sonoff SenseGuard Presence Core is a 4 metre occupancy sensor that answers only occupied or not occupied.
Does the Sonoff SenseGuard Presence Core need a hub?
Yes. It is a Zigbee 3.0 end device with no Wi-Fi, so it needs a coordinator such as a Sonoff Zigbee bridge, an iHost or a Zigbee2MQTT or ZHA dongle. The Aqara Presence Sensor FP2 needs no hub and connects directly over 2.4 GHz Wi-Fi.
Which one handles a still person better?
Both are radar presence sensors and both hold presence on someone who is not moving, unlike a PIR motion sensor. The difference is range and detail: the Aqara Presence Sensor FP2 adds zones and people counting, while the Sonoff SenseGuard Presence Core holds occupancy across a smaller area.
Does the Aqara Presence Sensor FP2 work with HomeKit and Matter?
It works with Apple HomeKit, Alexa, Google Home, SmartThings and Home Assistant directly, and it does not support Matter. Over HomeKit it reports presence as true or false rather than a person count, and it needs a constant USB-C power source.
Who should buy which one?
Buy the Aqara Presence Sensor FP2 for a large room, multi-zone automations or elderly fall and sleep monitoring. Buy the Sonoff SenseGuard Presence Core for a desk, hallway or small room in an existing Zigbee home, especially if you want the lux reading and mesh extension.
