Product Overview
Aqara Spatial Multi-Sensor FP400 turns a room into more than a motion trigger. Its 60 GHz mmWave sensor can map up to eight zones and track up to ten people in Aqara Home without using a camera, so a light or scene can respond to where a room is being used rather than only whether someone crossed a doorway. The richer spatial controls belong to Aqara's setup path; a chosen Matter controller may expose a narrower set of shared capabilities.
What Stands Out
FP400 brings zone-level presence and multi-person separation to a compact sensor instead of asking a camera to interpret the room. It can be mounted at the side, corner, or ceiling and uses USB-C power rather than a disposable-battery routine.
Why It Matters
Smart-home sensing becomes more useful when an automation can distinguish a sofa from a dining table or a doorway from an occupied room. FP400 shows the promise—and the ecosystem complexity—of that shift: the hub, controller, and placement decide how much of the spatial model reaches the home.
Best For
Aqara Home users and experienced Matter or Thread households that want camera-free room zones, can place USB-C power where the sensor belongs, and are comfortable checking platform-specific setup details.
Not For
Renters who cannot place a powered sensor where needed, users who want identical functions in every Matter controller, or anyone seeking a simple battery motion sensor.
Things to Know
Check the exact regional bundle, price, stock, supported hub or Thread border router, placement geometry, and the functions exposed in the intended smart-home platform before going further.
A compatible Aqara hub unlocks the full Aqara Home experience, while another Matter controller can expose a smaller set of functions. Do not assume that the full Aqara Home zone and tracking experience transfers unchanged to another Matter ecosystem.
Plan a powered mounting point and compare Aqara's stated side, corner, and ceiling coverage with the room. Firmware, room shape, pets, reflections, and chosen setup can change sensing behavior.
Treat independent reports of still-presence and false-trigger performance as setup-specific until broader long-term testing is available.
