Knows who is where, room by room.
A 60 GHz mmWave presence sensor that tracks up to 10 people across 8 custom zones, filters out pets and robot vacuums, and runs on constant USB-C power.

One sensor, eight independent areas.
FP400 tracks up to 10 people in real time on a 0.5 m × 0.5 m grid, so the sofa, dining table and walkway can each run their own automation without triggering one another. AI-assisted zone setup identifies room boundaries and likely interference sources to speed up configuration.
- Four zone types — monitoring zones, interference sources, entrances and boundaries for reflective walls and glass
- Real-time headcount — a local, subscription-free people count for occupancy automations
- Fine-tuned per room — adjustable sensitivity and absence-confirmation period
Stays sure when you sit still.
A 60 GHz mmWave radar with a 4T4R antenna array captures over five times denser point-cloud data than earlier Aqara generations, detecting the breathing movement of someone reading or asleep. With AI person detection enabled, it filters out pets, robot vacuums and moving objects. There is no camera, so no images are captured.
- AI spatial learning — adapts to the room and clears false targets caused by reflections
- Built-in light sensor — combine presence with ambient brightness for lighting automations
Wall, corner or ceiling.
A 120° field of view covers up to 10 × 8 m. Corner mounting uses the full angle and avoids blind spots along both walls; side mounting at 1.5–2 m or ceiling mounting at 3–4 m suits other layouts. IPX5 splash resistance means kitchens and bathrooms are fine, and constant USB-C power means no batteries to change.
- Always powered — 5 V ⎓ 1 A over USB-C for stable, long-term automations
- Wet rooms — IPX5 rated for indoor kitchens and bathrooms, away from direct steam
Works with an Aqara hub or straight into Matter.
FP400 runs on Zigbee or Matter over Thread. Pair it with a supported Aqara hub, or set it up in the Aqara Home app through a compatible third-party Thread border router such as an Apple home hub. Either way you configure zones, sensitivity and absence timing in Aqara Home, then share one whole-area occupancy sensor and up to eight zone sensors with Apple Home, Google Home, Amazon Alexa, SmartThings or Home Assistant over Matter.
- Supported Aqara hubs — Hub M3, M100 and M200, Doorbell Camera Hub G410 and Camera Hub G5 Pro; MagicPad S1, Panel Hub S1 Plus and Camera Hub G350 support is due during 2026
- Not supported — Hub M2, M1S, M1S Gen 2 and E1, Camera Hub G3 and G2H Pro, and the Smart Video Doorbell G4
Settle into the sofa and the room follows.
Sit in the sofa zone after 7 pm and the ambient lights come on and the air conditioner eases into comfort mode.

Hub compatibility follows Aqara's published list and can vary with region and firmware; keep your hub updated. Sharing zones to a third-party platform needs that platform's Matter controller and Thread border router. FP400 does not detect falls or posture. Coverage figures are laboratory maximums; mounting height, reflective surfaces and obstructions reduce real-world range. Headcount can vary by one to three people when people stand close together.
Frequently asked questions
Which Aqara hubs work with the FP400?
Aqara currently lists the Hub M3, Hub M100, Hub M200, Doorbell Camera Hub G410 and Camera Hub G5 Pro as supported. Support for the MagicPad S1, Panel Hub S1 Plus, Camera Hub G350 and Thermostat Hub W200 is due during 2026. The FP400 does not work with the Hub M2, Hub M1S, Hub M1S Gen 2, Hub E1, Camera Hub G3, Smart Video Doorbell G4 or Camera Hub G2H Pro. Compatibility can vary with firmware, so keep your hub updated.
Can I use the FP400 without an Aqara hub?
Yes. With a compatible third-party Thread border router, such as an Apple home hub, you can set the FP400 up in the Aqara Home app without an Aqara hub, configure its custom zones, sensitivity and absence timing, and then share one whole-area occupancy sensor plus up to eight zone sensors with Apple Home, Google Home, Amazon Alexa, SmartThings or Home Assistant over Matter. That needs the platform's Matter controller and Thread border router.
Will it ignore pets and robot vacuums?
With AI person detection turned on, the FP400 filters out non-human targets such as pets and robot vacuums; small children can occasionally be classed as pets. You can also mark a pet bed, fan or curtain as an interference-source zone, or lower the sensitivity, to reduce false presence.
Where should I mount the FP400?
A corner is usually best: it uses the full 120° field of view and avoids blind spots along both walls. Side mounting works at 1.5–2 m high and ceiling mounting at 3–4 m. The sensor needs constant USB-C power (5 V, 1 A), so plan a power point or cable route. It is IPX5 splash resistant and suitable for indoor kitchens and bathrooms, away from direct steam and flames.
How is the FP400 different from the FP2 and FP300?
The FP400 tracks up to 10 people across 8 zones and runs on Zigbee or Matter over Thread with USB-C power. The FP2 uses Wi-Fi rather than Zigbee or Thread, supports up to 30 zones and adds fall detection when ceiling mounted. The FP300 is battery powered, combines mmWave with PIR and adds temperature and humidity sensing, but reports whole-room presence without zones. The FP400 does not detect falls or posture.
