Aqara FP300 vs FP2 in a studio: batteries or room zones?

Sketch the automation before choosing the sensor

Draw the studio’s bed, desk and sofa on paper. Write one useful action for each area. If the only action is turning the room lights off after everyone leaves, one occupancy signal may be enough. If lights should behave differently while someone reads on the sofa and someone else sleeps, room zoning becomes a different requirement.

Do not treat an advertised detection range as proof that the sensor will work from any shelf. Furniture, line of sight, placement and configuration matter. A camera-free sensor still produces information about occupancy and routines; discuss it with housemates before installing it.

Choose the type of information first

Budget the complete network route

FP300’s Zigbee and Thread modes are alternatives with different setup requirements and exposed features. For the supported Aqara Zigbee route, include a compatible Aqara hub. For Matter over Thread, verify both a Matter controller and Thread border router, plus current platform support. An app on a phone is not automatically all of that infrastructure.

FP2 is not simply a Wi-Fi version of FP300. Confirm its documented integrations for your platform and verify that your permitted network allows the necessary local communication. A building network with client isolation may be unsuitable even when browsing works. Do not disable network protections to make commissioning easier.

Power and placement can decide the purchase

For FP2, plan a continuous USB power route that does not cross a walkway or require changing fixed wiring. For FP300, plan access for battery replacement and use the documented mounting and orientation. Battery-powered does not mean mounting permission or furniture position no longer matters.

Aqara’s battery-life claims depend on its test conditions and the selected mode. We have not measured them. Start with a simple automation and check it through ordinary seated, sleeping and empty-room situations before expanding the system; do not use a documentation-based comparison as a reliability certification.

Choose the sensor for the actual layout

Keep a manual route and rebuild after moving

Do not start by making every light depend on detection. Keep switches or remotes available and agree who can view occupancy history. A presence sensor’s fall-related or other additional features should not be treated as a certified emergency response service.

Move the device with its mounting parts, remove old household access where appropriate and redo learning or mapping in the new layout. A sensor that worked beside the old sofa has not been validated behind a different cabinet. For a simpler control that does not infer occupancy, compare physical light remotes.
