Choose FP2 when different parts of a room should trigger different actions; choose FP300 when easy battery placement and room-presence sensing matter more. FP300 is not a reason to discard a well-configured FP2 zone map. It solves a different installation problem: placing a presence sensor where an always-on USB cable would be awkward, while also gathering environmental readings.

Which difference changes your lighting plan?

What changes in daily use

Primary task	dividing them into up to 30 zones.	Combines PIR and 60 GHz mmWave radar to accurately detect both motion and still presence
Power	the FP2 is a wired sensor that should be constantly powered	Powered by two CR2450 batteries
Additional sensing	Built-in Light Sensor	Built-in temperature, humidity, and light sensors

An open room can contain several jobs. You might want a desk lamp while working, kitchen lights while preparing food and different behavior around the sofa. FP2's documented zone positioning addresses that kind of layout. Decide whether the automation needs to know where you are within the room, rather than simply whether someone remains there.

For a smaller room with a single lighting group, a whole-room presence rule can be enough. FP300 becomes attractive when you want a useful sensor position without arranging continuous USB power.

When is FP2 worth the cable and setup?

FP2 supports dividing a room into zones, with wall mounting required for zone positioning and multi-person detection. That installation detail belongs in the buying decision. A convenient shelf position or ceiling location should not be assumed to provide the same documented zone workflow.

It also needs constant power. Work out the USB route before buying: where the cable runs, whether the outlet is accessible and whether the final position gives the intended view of the room. A powerful automation feature is less valuable if you cannot place the sensor where it can serve that task.

Aqara says no Aqara hub is required for the FP2 integration route it describes, and documents exposure to compatible ecosystems. Its local-automation scope is more specific: other Aqara or Apple Home-compatible devices. Match the actual lights and controlling app rather than reading hub-free as universally dependency-free.

What does FP300 offer beyond removing a cable?

FP300 combines PIR and mmWave sensing and documents detection of both motion and still presence. It also includes temperature, humidity and light sensors. Those readings are useful when you want the room to react to occupancy and conditions together, instead of buying a sensor purely to notice someone walking past.

The network choice affects the settings. FP300 supports Zigbee and Thread; Aqara lists detailed detection-range, absence-delay and reporting controls in Zigbee mode through Aqara Home. Choose the mode around the rules you want to tune. Do not assume every Matter app exposes every manufacturer setting.

Battery operation improves placement options, but it still creates a maintenance task. Treat the published battery duration as conditional on settings and use. A sensor installed where changing batteries is difficult trades a visible cable for an occasional access problem.

Should an FP2 owner switch to FP300?

Keep FP2 when its zones are doing useful work. FP2 has an explicitly documented zone workflow; these sources do not establish that FP300 reproduces that same room map. Keep the working setup until any proposed replacement is confirmed to meet its actual rules. If the current installation is awkward because the only power point is in the wrong place, revisit the job: perhaps a simpler whole-room rule and battery placement would be a better fit.

For a new buyer, sketch the room and write each desired light response. If several locations need distinct actions, start with FP2. If a single occupied-or-empty decision plus environmental readings is enough, start with FP300.

We have not tested either sensor's false-trigger rate or pet behavior. Configure and observe the chosen setup in your room before shortening absence delays. A reliable lighting routine is the purchase goal; the radar specification alone cannot guarantee it.

What are the checked package prices?

The checked Aqara US sensor prices are $82.99 USD for FP2 and $49.99 USD for FP300. Their listed-price difference is $33.00. We would pay for FP2 when room zones are central to the automation, while FP300 addresses the different need for battery placement and its additional environmental sensors. Include required platform hardware separately; tax, shipping and promotions can change checkout totals.

Open-plan space with different lighting areas

Choose FP2 when zone-specific presence is the point of the purchase and you can provide the documented mounting and constant power.

Room with an awkward outlet position

Choose FP300 for battery placement and environmental readings when whole-room occupancy is the useful decision. Keep the settings and ecosystem requirements in the plan.

Frequently asked questions

Is FP300 a direct upgrade from FP2?

Treat them as alternatives for different jobs. FP2 emphasizes zone positioning; FP300 emphasizes battery-powered presence and environmental sensing. The documented FP2 zone workflow is a reason to keep a functioning setup; do not assume another sensor reproduces that map simply because its name looks newer.

Does FP2 need to stay plugged in?

Yes. Aqara explicitly describes FP2 as a wired sensor that should be constantly powered. Plan the cable and outlet before buying, and remember that its zone-positioning installation specifically calls for wall mounting.

Can FP300 detect someone who sits still?

Its official description combines PIR and mmWave sensing for motion and still presence. That is the relevant capability for seated use, but the real room still needs configuration and observation. This article does not claim measured detection reliability.

Which FP300 settings depend on Zigbee mode?

Aqara documents advanced range, absence-delay, reporting-frequency and individual-sensor controls through Aqara Home in Zigbee mode. Select the protocol around the controls you need, rather than assuming every function will be available through every Matter integration.
