Aqara FP2 Presence Sensor

Aqara FP2 Presence Sensor

The Aqara FP2 Presence Sensor uses advanced millimeter wave radar technology that can accurately detect the presence of people, even with slight movements. This technology ensures the continuity and stability of smart devices. It also has a zone positioning function that allows for the automation of different conditions in different zones, such as beds and desks. A single space can now be divided into up to 30 small areas and recognize up to five targets (multiple person detection). It can also control other smart home devices through ecosystems such as Apple Home to achieve broader applications. It includes features such as human fall detection and a built-in light sensor. It is also an excellent assistant that can truly integrate the diversity of a user's home life and realize the automation of different personalities.

Highlights:

Cons position: offers significant advantages over traditional PIR infrared motion sensors by using a single radar sensor to monitor areas of up to approximately 430 square feet (approximately 40 m²)*. In addition, it can be divided into up to 30 areas, such as a sofa, bed, or desk. Furthermore, individual automation can be set for each zone. This is equivalent to using multiple PIR motion sensors simultaneously with a single presence sensor, FP2.

Multiple person detection: Up to 5** target persons can be detected simultaneously. As a result, it can automatically respond to the positions of different people when dividing the space without interfering with each other.

Extremely high accuracy: Privacy and detection accuracy are taken into account. It is capable of non-inductive signal detection without collecting actual images.
Automation can generally be achieved locally. Millimeter wave radar technology is more stable than infrared sensor detection, even when you are sitting or sleeping.

Control other devices via HomeKit, etc.: FP2 is exposed as multiple sensors in HomeKit (and Home Assistant), Alexa, and Google Home. You can easily integrate the sensor without the need for a hub, which is obviously the best solution for smart home enthusiasts to expand their smart home setup.****

Fall detection and alerts: When someone in the room falls, FP2 can detect it and notify you. It is designed to be as private and convenient as possible, without the need to wear any devices or install a camera for constant monitoring. The range is a circle with a radius of 2 meters, and the fall detection accuracy is >98%. The recommended installation height is 2.5 m-2.8 m.

Built-in light sensor: a fully functional light detection sensor in the Aqara ecosystem. It makes lighting automation much more flexible and convenient. The built-in light sensor also enables advanced home automation based on darkness.

Local automation and flexible installation modes: Once setup is complete, the product runs locally. FP2 automation will still work as originally set up if there is occasional Wi-Fi network instability. And it better protects your privacy. It has multiple installation modes to adapt to different installation scenarios.

IPX5 and hidden USB-C port: Due to its IP rating, the sensor can also be installed in wet environments such as bathrooms. The sensor has an open USB-C port, allowing you to replace the included cable with any compatible USB-C cable, increasing installation flexibility.

Disclaimers

*The recommended detection area is 10 m³ -40 m³.

** Best results can be achieved when tracking up to 3 people.

***Only ceiling mounting is supported for fall detection. Fall detection can only recognize most common fall scenarios and cannot be used as a substitute for medical equipment or vision. Currently, fall detection cannot distinguish between a slow fall against a wall and unconsciousness after sitting down.

****Bluetooth is available for the upcoming Matter feature.

Use cases:

Scene 1: "Redefining Space" scene.

In the past, smart home users often had to install small motion sensors in various locations. Due to the limited detection range and capacity of the sensor, users had to install multiple sensors. This resulted in inconvenient user management, difficult settings, and other problems.

FP2 redefines "virtual space" in the application. It redistributes the space within a range of 40 m³ (8 m × 6 m). This means that within this range, users only need one human presence sensor to achieve customized automation in multiple virtual small spaces, reducing the clutter and energy consumption of users who operate multiple sensors. Now, one FP2 presence sensor is roughly equivalent to the current use of multiple old sensors, enabling continuous energy savings. A simple life begins with the simplification of smart home devices.

Scene 2: Silent reading scene

Traditional PIR motion sensors usually cannot detect when a user is sitting quietly. As a result, some automation equipment cannot detect and interrupt its work. Therefore, users often have to wave their hands to trigger sensor detection.

When users automate with old PIR motion/presence sensors, it often happens that automation detection cannot be triggered due to quiet sitting. Using FP2 can effectively solve this problem. The millimeter wave radar technology used by FP2 can continue to detect even when the user is sitting still by detecting the user's heartbeat and breathing.

Scenario 3: Control other smart home devices by connecting to Apple HomePod mini, etc.

Suitable for users who already have Apple Home, Google Home, and Amazon Alexa at home. In the past, users used third-party products and often needed voice interaction to start other devices. Is there any other way to make the user's intelligent connectivity behavior natural without spending too much effort?

FP2 is connected to the Apple HomePod mini device. The user only needs to enter a specific small area, and FP2 will detect the presence of a human body, which can trigger other smart lights to respond by turning on.

Scene 4: Fall detection and reduction of fall-related injuries (new sensor users)*

Falls are common among the elderly. Knowing about a fall as soon as possible is an important way for the elderly to prevent serious injuries caused by falls, especially for those who live alone. Therefore, it is very important to detect a fall in a timely manner and receive informative reminders.

FP2 is installed in relatively narrow spaces with ceiling mounting, such as kitchens, toilets, or bedrooms. Real-time fall status detection and remote feedback in the app allow family members far away to receive faster alerts and alarms.

*Fall detection can only recognize most fall scenarios and cannot be used as a substitute for medical equipment or vision. Current fall detection cannot distinguish between a slow fall against a wall or unconsciousness after sitting down.
Examples of automation scenarios:

1. Lean Away mode without delays.

IF presence sensors in each room detect absence, THEN turn off the lights, air conditioning, and activate the alert system.

Previously, you had to wait several tens of minutes to make sure that absence mode would not be triggered when someone was at home. Now you can save energy and increase protection without manually enabling absence mode.

2. Wake Up automation that doesn't disturb your family members.

IF someone enters the bathroom while a presence is still detected in bed, THEN do not open the blinds*.

*Two automations need to be configured: for presence and absence in the bed zone. FP2 can detect if someone is still in bed, and Wake-Up automation will not be triggered if another person wakes up.

3. Accentuated lighting that follows you.

IF presence is detected on the desktop, THEN turn on the appropriate lights.

The lighting can now follow you around the room: only the lights near you will be turned on, while the other lights will turn off if you leave the area!

4. Detect presence and start protecting your home.

IF presence is detected in the living room, THEN turn on the Aqara G3 camera for monitoring.

Turn on the G3 camera to detect the presence of people in a larger space: if the FP2 detects someone, the G3 camera will automatically turn on for monitoring and can pan around the living room.
