Choose Aqara FP1E when a powered position and compatible Aqara Zigbee setup already fit the room. Choose Aqara FP300 when battery placement or its supported environmental readings solve a real installation need. Both address presence rather than just the moment someone walks in. The useful distinction is where the sensor can go and which readings the chosen setup exposes.

Will either address the seated-room task?

FP1E documents mmWave sensing for movement and still status. FP300 combines its radar and PIR arrangement to detect motion and still presence. That makes both more directly relevant to occupied-room lighting than buying solely for a doorway arrival. We do not claim either detects every still person perfectly, or rank response accuracy without testing. Begin with the seat or desk that must keep a light useful. Choose the sensing position and automation behavior around that task rather than infer perfect occupancy from the word presence.

Is a power cable the real installation problem?

FP1E’s documented power specification is 5 V⎓1 A. FP300 uses the stated replaceable batteries. Battery operation gives another placement option where a suitable supply is inconvenient; wired power avoids planning periodic battery replacement. Look at the actual wall, corner or ceiling point before choosing. Hiding a cable should not put the sensor where the important seat is obstructed, while battery convenience does not make every mounting location appropriate. We report the documented power methods rather than promise measured battery endurance or a maintenance-free wired device.

Which ecosystem route fits the equipment you own?

FP1E requires a compatible Aqara Zigbee hub and supports its documented Matter-over-bridge route. FP300 supports Zigbee or Thread. Those paths should be chosen around the actual controller and functions intended. A protocol label is not a universal guarantee that every reading appears in every app. FP300’s cited configuration controls are scoped to Zigbee mode and Aqara Home. Choose a supported rule and verify what the destination platform exposes instead of treat Thread and Zigbee as identical ways to access every native setting.

Do extra environmental sensors earn a place?

FP300 documents temperature, humidity and light readings. Those are useful when the room plan has a real condition to use, such as combining presence with the supported brightness reading. They add little when all you want is an occupied/unoccupied rule. FP1E remains a focused choice when presence is the whole task and the compatible hub is already installed. Do not charge the entire previous hub purchase again when deciding to keep that setup. A new buyer without required controller equipment must compare the complete configurations instead of only the two sensor amounts.

What is the complete buying cost?

The checked listed hardware reference prices are $49.99 USD and $49.99 USD. The listed hardware difference is $0.00, using the stated configurations and source-check dates. Retailer buttons can lead to a different checkout price. Add the storage, power, compatible controller or installation described above before comparing complete setups. For an existing owner, keeping working equipment avoids the full replacement purchase; the price difference between two new boxes is not the cost of upgrading.
