Presence Sensor FP2


What can Presence Sensor FP2 do?

Presence Sensor FP2 can detect presence/absence, falls, events of someone entering, leaving, approaching, going away and illuminance, and supports real-time tracking of multiple targets and zone settings.

Can Presence Sensor FP2 support multi-person detection?

Yes, it supports tracking up to 5 targets. Yet the best result can be achieved in case of tracking not more than 3 persons.

What is the detection zone?

The detection zone enables users to configure zone automation. Users can select from 320 cells provided for better automation setup, such as setting the sofa, bathroom, study, and dining table. Set zones will be added to the automation conditions. You can create up to 30 zones.

What is the use of stickers?

The stickers are used for reference so that users know more accurately where the target is located. The stickers will not affect the device's detection performance.

What is the use of the interference source, entrance and exit, and edge settings? Are they necessary?

FP2 applies millimeter-wave technology, which is sensitive to moving objects. The more complete setup is, the more accurate the detection can be.
1) Interference: Living and office spaces often have moving targets such as curtains, fans, green plants moved by wind, and clothes hanging. If the sensor detects these objects, a false alarm may easily occur, so it needs to be marked as an interference source. Currently, the interference source marking is mainly for objects with smaller emission signals, such as green plants and running water.
2) Edge: The setting of the edge is mainly used to counteract false targets caused by a wall or other object reflection signals. The area outside the wall is also suggested to be set as the edge. 
3) Entrance and Exit: It can accelerate target creation and deletion speed and improve the user experience.

What is the button on the FP2 used for? What happens if I press it?

The button is used for device resetting.
1) Press and hold for 10 seconds to reset the network.
2) Press it quickly 10 times to restore the factory settings.

How to add FP2 to Aqara Home app?

Open the Aqara Home app > tap "Home" >"+" in the upper right corner of the app > "Add accessory" > search "Presence Sensor FP2" > add it according to instructions

Does FP2 support local automation?

Yes, but a hub with a version of 3.5.0 or above that supports Wi-Fi local automation is required.

What is the proper distance between FP2 and the hub? Can its detection penetrate walls?

When used in home environments, the recommended distance between the FP2 and the hub should not exceed 20 meters. There shall be no more than two walls between them.

How can I verify if the installation position of the FP2 is proper?

1) After binding successfully, if the device homepage can display a small icon of a person whose motion is consistent with yours, then the device can normally report the location data. (Note: There will be a delay in device display, due to the communication between the device and the server.) 
2) If an absence is detected within 30 seconds after leaving the detection area, it means that the current installation position of the device can function normally. The quicker the response is, the less interference there is, and the easier for the sensor to detect accurately. If an absence event takes a long time to occur or is not reported, it means that there is some interference in the space. Please check your environment and move somewhere else to configure the device.
3) When it is installed, please avoid moving objects and moving objects within a certain period to avoid false alarms.

Why does FP2 sometimes go offline?

The device may be too far away from the Wi-Fi router or there are metal obstacles in between. You can try to move it closer to the router and avoid metal obstacles.
Note: To achieve a better experience, please upgrade the device firmware in a timely manner to ensure compatibility and stable communication between devices.

How to set up automation based on zone detection?

After setting up the zone, the automation condition will add zone detection, which supports zone automation. For example, if you set up a sofa zone, you want to set up the light to turn on when entering the sofa zone: Click the "+ " in the upper right corner of the automation page, select FP2 > Zone Detection> Zone > Enter in the "IF" section, and select the light> Light in the "Then" section to complete the automation setting.

What is the detection range of FP2?

When wall-mounted, the horizontal detection angle is 120 degrees, and the radial distance is about 8 meters. When ceiling-mounted at a height of 2.8 meters, it can cover a radius of 2 meters.

What is approaching automation? And what is the distance setting for?

Users can configure automation for approaching the sensors or zones, such as turning on the light when approaching the zone. The three levels of distance represent 1 meter, 2 meters, and 3 meters, respectively. After setting it up, entering this threshold from a distance will trigger an approaching event, and leaving this threshold from a close distance will trigger a going-away event.

How is the Left-Right Detection mode differ from Default mode?

Default mode can detection presence within the detection zone. The Left-Right Detection mode can detection the direction of presence entering/leaving from both sides of the zone to help better distinguish scenes. For example,in scenes where entering/exiting needs to be distinguished,left and right detection can be selected. Default mode is the basic setup, while Left-Right Detection mode will require a larger amount of data transmission than the former. If there is no need for directional detection,it is recommended to turn on default detection mode.

How to improve the accuracy of zone detection (avoid false alarms, missed alarms, ghosting, delays, etc.)?

1. Installation Location: Select a location free from disruptions like glass, mirrors, metal, water, air conditioners, fans, and curtains. If such interference can't be avoided, position these elements in the FP2 monitor's blind spots.

2. Device Installation: Mount the device at a suitable height on the wall, ensuring the logo is level. The device covers a 120-degree horizontal and 20-degree vertical detection range, up to 8 meters. Incorrect installation height can lead to detection errors and false alarms.

3. Edges Configuration: Define the maximum detection area and set other areas as edges.

4. Entrances and Exits Configuration: Properly setting up entrance and exit is crucial for efficient target recognition and elimination, ensuring timely and precise detection.

5. Interference Configuration: Identify and mark areas with potential disturbances, such as air conditioners, fans, or moving curtains, as interference zones.

6. Presence Monitoring Sensitivity: Adjust sensitivity to ensure better detection of subtle movements, facilitating the activation and maintenance of the “presence” status.

7. Space Intelligent Learning: Conduct “Space Intelligent Learning” when the area is unoccupied to reduce environmental and background noise interference.

8. AI Person Detection: Enable this function as needed to minimize false alarms caused by non-human movements like robot vacuums and pets.

9. False Alarm Management: In case of false alarms due to interference, adjust the settings to account for these elements while removing the target.

What are the processes and precautions for adding FP2 to Apple HomeKit

To add FP2 to Apple "Home", ensure that your phone and the home hub (such as HomePod) are connected to the same local network. The phone should be connected to a 2.4GHz WiFi or mixed-frequency WiFi (supporting both 2.4GHz and 5GHz). Follow the "Home" prompts to scan the HomeKit QR code on the back of the device for networking and adding the device. Detection area-related settings are made in the Aqara Home App and can be synchronized with HomeKit.


1. If the Apple HomeKit home does not have a hub added: FP2 can still be networked and used normally, but local control is not available.
2. If the Apple HomeKit home has a hub added: When networking, the phone and hub must be connected to the same local network.
3. For localized control of FP2, it requires that FP2 and the home hub be on the same local network.


Error Code 74: If the Apple HomeKit home hub is offline or the hub and phone are not on the same local network, Error Code 74 will be displayed. Please connect the phone, FP2, and the hub to the same local network.

Can I use the sleep monitoring, zone Detection, and Fall Detection modes simultaneously?

The FP2 features 3 distinct modes that can't run simultaneously. You can switch to your desired mode, and each comes with specific setup method. Between modes, respective guidance is provided.

How can I improve my sleep report accuracy?

To improve sleep report accuracy:
1. Fine-tune the exact position of your monitored zone.
2. Minimize interferences. Devices like air conditioners, fans, and curtains might disrupt the radar's scan. Try to keep them away or turn them off.
3. Run "AI Space Learning" when the room is in "absence" state. This will help improve detection accuracy.
4. Adjust the monitoring sensitivity: higher detects small movements but may miss "absence" events; lower minimizes false alerts but could miss actual movements.
5. Note that sleep monitoring is designed for single-person detection. For a shared sleeping environment, set the monitoring zone to one side to minimize interference.

How should I set the right detection sensitivity for sleep monitoring?

The working principle is the same as presence detection. If you're getting false “absence" notifications, increase the sensitivity. If you don’t receive any when leaving the bed, then decrease it.

Can FP2 sleep-monitors two people?

Sleep monitoring is designed for single-person monitoring. For monitoring two people, it's recommended to install separate FP2s and set distinct sleeping areas for each. Note that nearby objects may still interfere with sleep reports.

Will a thick blanket disrupt the accuracy of sleep monitoring?

No. The millimeter-wave radar can detect subtle body movements like breathing. With FP2's AI algorithms, the device smartly assesses sleep based on movements, heart rate, and other metrics.

Does monitoring with millimeter-wave radar have any impact on human health?

Millimeter-wave radar, widely utilized in smart home applications, operates at frequencies that are in compliance with established human safety standards. The level of radiation emitted by FP2 is significantly lower than harmful thresholds and the radiation from mobile phones which is generally considered safe for everyday use.

Will multiple FP2s in the same room interfere with each other?

Multiple FP2s in the same space generally won't interfere if not directly facing each other, allowing simultaneous operation in various modes.

How is the heart rate data consistent with the heart rate watch?

1. FP2 employs radar technology to detect chest movements and subtle heartbeat fluctuations for assessing the user's respiration rate and heart rate. However, the heart rate readings may vary from those obtained by professional medical equipment.
2. Due to radar technology's limitations and the device's algorithm, FP2 accurately measures respiration and heart rates during static conditions but is unsuitable for use during motion.
3. FP2 is not a medical device and should not be used for diagnosing or preventing sleep-related disorders. For personalized medical guidance, consult a healthcare professional.
