Aqara Presence Sensor FP2, mmWave Radar Wired Smart Motion Sensor, Zone Positioning, Multi-Person & Fall Detection
Quick take
The Aqara Presence Sensor FP2 is a wired mmWave radar presence sensor that’s built for precision automations, including up to 30 custom zones and multi-person detection. It can also support ceiling-mounted fall detection and inactivity alerts for elder-care style monitoring, and it runs local automations without cloud for supported features. If you want a straightforward “mount and forget” PIR replacement, expect a steeper setup curve because zoning and platform integration matter a lot.
Pros and cons
Pros
- mmWave radar presence detection designed to outperform typical PIR motion behavior (single sensor, up to 40㎡ coverage, up to 5 people).
- Flexible automation building with up to 30 zones and interference filtering (exclude objects like plants, curtains, or pets).
- Wired power with no battery to manage during use.
- Ceiling-mount option enables fall detection mode, plus inactivity-based alerts.
- Supports multiple ecosystems (HomeKit, Alexa, Google Home, and Home Assistant).
Cons
- Requires app-based setup, and zoning can take time to get right before you see reliable results.
- Power adapter is not included, and the sensor should stay continuously powered during use.
- Some integrations may show limited information (for example, presence as a boolean per zone rather than person counts).
- Fall detection mode is limited to ceiling mounting.
What buyers think
Buyer-review evidence is mixed but theme-driven. Many buyers highlight the appeal of multi-zone automation, including using the sensor to replace multiple motion sensors and create more tailored routines. Usability themes generally point to “easy once set up” for tech-comfortable users, and they also mention that setup and tuning (especially zones) can require patience. A smaller but recurring concern is occasional detection misses or “false presence” scenarios that can require cleaning up zones or filters in the app. On the integration side, reviewers also note that certain setups can be finicky, including information granularity in Home Assistant/HomeKit and cases where the device may require attention if it stops working in a specific workflow.
Who this is best for
- Smart home power users who want presence-triggered automation, not just motion events, and are willing to spend time configuring zones.
- People who care about privacy since the FP2 is a radar-based sensor and does not require a camera for presence detection.
- Users interested in elder-care style features like inactivity alerts, and who can mount the device on the ceiling if they want fall detection mode.
Who should avoid it
- Buyers who want simple, low-effort installation. If you prefer “mount it and it just works,” zoning and app configuration may feel like too much.
- Anyone unwilling to wire the sensor and keep it powered. The unit is wired and expects the correct 5V 1A power adapter (not included).
- Shoppers depending on very specific platform data. Some ecosystems may not surface as much per-zone detail as you’d expect (for example, whether it can provide person counts).
Key features that matter in everyday use
Multi-zone positioning for targeted automations
The FP2’s biggest practical differentiator is zone-based detection. You can create up to 30 zones (for example, bed, sofa, desk) and then tie those zones to different automations. That means you can build behaviors like “only turn on under-cabinet lights when someone is at the kitchen area,” rather than triggering everything whenever the room sees movement.
mmWave radar presence detection and filtering
Instead of relying purely on motion, the FP2 uses millimeter-wave radar to detect human presence and can help reduce unwanted triggers by defining interference areas and filtering out non-human movement (such as plants or curtains). The product also mentions filter height controls to ignore fan movement or crawling pets, which is useful in real homes where PIR sensors can be overly sensitive.
Multi-person detection
If your use case includes multiple people in the same room, the FP2 is designed to detect up to 5 people at the same time. In practice, that’s most valuable when your automations should respond to occupancy in different areas (zones) rather than simply “someone moved.”
Ceiling-mounted fall detection and inactivity monitoring
For fall detection, the FP2 is meant to be ceiling-mounted. When enabled, it can send alerts through the app if a fall is detected. It can also trigger alerts when there is unusual inactivity, making it a potential option for independent living monitoring scenarios.
Built-in light sensing for smarter routines
The FP2 includes a built-in light sensor, which can expand automation options like adjusting lighting behavior based on ambient brightness. This is noted as being available through Aqara Home, HomeKit, and IFTTT, so it may not apply the same way across every integration path.
Setup and integration considerations
Several buying themes point to a reality with presence sensors: calibration is part of the job. You will likely want time to map the room, define zones, and then tune interference areas so routine household movement (and non-human movement like fans) does not produce unwanted triggers. Also, the FP2 must be connected to Aqara Home before enabling skills in Google Home and Alexa, and Home Assistant can be handled via HomeKit Controller integration. If you plan to build automations across multiple platforms, decide early which ecosystem will be your “source of configuration truth.”
Pros and cons summary
- Pick it if you want mmWave presence detection with multi-zone control to create more precise automations than PIR typically offers.
- Think twice if you want a quick-install sensor or you rely on very specific per-zone presence data in your smart home hub.
- Plan for setup time because zone placement and tuning appear to be central to getting good results.
Verdict
The Aqara Presence Sensor FP2 is a strong fit for smart home shoppers who want presence and occupancy automations with room zoning, especially in spaces where multiple people or more nuanced placement is hard to manage with standard PIR sensors. It is less ideal for buyers seeking minimal setup effort or who need “plug-and-play” behavior across every platform with the same level of detail. If you are willing to tune zones and keep it properly powered, the FP2 can replace multiple motion sensors and unlock more targeted routines.

FAQ
Is the aqara presence sensor FP2 a battery-powered motion sensor?
No. It is a wired device, and it requires a 5V 1A power adapter that is not included. The unit should be kept continuously powered during use.
Does the FP2 work without a camera?
Yes. It uses millimeter-wave radar for human presence detection and does not require a camera for its core sensing functions.
How many zones can you create with the FP2?
You can create up to 30 zones, such as different areas like a bed, sofa, or desk, and link each zone to automations.
Can it detect multiple people at once?
Yes. The FP2 is designed to detect up to 5 people at the same time.
Does fall detection require ceiling mounting?
Yes. Fall detection mode is intended to work when the sensor is ceiling-mounted.
What smart home platforms does it support?
It supports HomeKit, Alexa, Google Home, and Home Assistant. The integration approach may differ by platform, and Home Assistant can use HomeKit Controller integration.
Is local automation supported?
Yes. The FP2 is described as executing automations without sending to the cloud for supported local execution, which can help it continue working when there is no internet connection.
