The **Aqara FP400** combines 60GHz mmWave radar with on-device AI to track where people are, how they are positioned and whether someone has fallen, and it went on sale worldwide on September 16, 2026 at $79.99 in the United States and €79.99 in Europe. The device succeeds the Presence Sensor FP2, which Aqara launched roughly three and a half years earlier. Aqara has moved from the FP2's zone-heavy layout to a model built around ten simultaneous people, adding noise-suppression algorithms alongside Zigbee support and Matter over Thread. ## What the Aqara FP400 Senses Radar does the work, not optics. The FP400 locates up to ten people at once, sorts them into as many as eight configurable zones, and covers a floor area of about 80 square metres, a field close to 10 by 8 metres. It classifies posture as standing, sitting or lying, counts occupants in real time, and logs how long they stay in a space and how far they travel. A built-in light sensor feeds brightness readings into the same automation engine. The unit is permanently powered rather than battery-operated, which suits the continuous radar sampling it depends on. Fall detection works from a side-wall mount, with exclusion areas that let an installer mask parts of a room where a fall should not be flagged. The distinction from older hardware matters here. Passive infrared detectors register movement only, so a person sitting still disappears from their view. mmWave radar reads stationary presence, which is the difference between a lamp that stays lit while you read and one that switches off. Aqara frames the product as spatial intelligence rather than motion detection. Knowing that two people are in the kitchen, one seated and one standing at the counter, gives an automation engine more to work with than a binary occupied signal. That extra context is what turns sensor data into rules: lighting that follows a person between zones, heating that backs off in empty rooms, and fall alerts that do not depend on anyone pressing a button. ## Matter and Thread Change Who Can Use It The FP400 speaks Thread and Zigbee natively and is Matter-enabled. A household already running a Thread border router, such as a HomePod mini, a second-generation HomePod or a 2021-or-later Apple TV 4K with Ethernet, can add the sensor to Apple Home, Google Home, Amazon Alexa or SmartThings without routing every action through Aqara's own app. Aqara lists five compatible hubs of its own: the Hub M3, Hub M100, Hub M200, Doorbell Camera Hub G410 and Camera Hub G5 Pro. Those unlock the full feature set, including the zone editor and posture data. Third-party Matter platforms see a narrower device profile. That split shapes the buying decision. Matter interoperability lowers the cost of leaving Aqara later, but the advanced spatial features still sit behind Aqara's hub and app layer. For an existing Aqara household the FP400 is a $79.99 addition. For a home starting from nothing, it is the first step into a system. Two installation details shape real deployments. Coverage tops out near 80 square metres, enough for an open-plan living and kitchen area but not an entire floor, so larger homes will need more than one unit. The sensor also depends on a hub or a Thread border router to work at all; there is no standalone mode, and without either device it has no route onto the network, which adds hardware to the bill for a household that owns neither. Standards work is heading the same way. Matter version 1.7 is drafting broader sensing support, which would make radar-style occupancy data a recognised device class across ecosystems instead of a vendor-specific extra. ## Two Versions, Two Audiences Aqara sells the hardware in two variants. The standard FP400 targets home automation, with multi-zone positioning built for lighting, climate and security routines. The FP400 Pro is aimed at assisted living and high-end home care, adding activity recognition and assisted fall detection for older or care-dependent residents. Aqara showed the Pro model at CEDIA Expo 2026, after previewing the line at IFA 2026, and markets both versions as alternatives to camera and wearable monitoring. | Spec | Aqara FP400 | | -------------- | ----------------------------------------------------------------------------------------- | | Price | $79.99 / €79.99 | | Availability | Global, from September 16, 2026 | | Sensing | 60GHz mmWave radar with on-device AI | | People tracked | Up to 10 simultaneously | | Zones | Up to 8 configurable | | Coverage | About 80 m² (10 × 8 m) | | Recognition | Posture (standing, sitting, lying), falls, occupancy counts, dwell time, walking distance | | Radios | Thread and Zigbee, Matter-enabled | | Hubs | Hub M3, Hub M100, Hub M200, G410, G5 Pro | | Variants | FP400 (home automation), FP400 Pro (assisted living) | The privacy argument rests on what the sensor never produces. There is no image to store and no footage to stream; the FP400 outputs coordinates, zone states and posture classifications. In a bedroom or a bathroom, where a camera is rarely acceptable, that difference decides whether monitoring is possible at all. Elder care is where the trade-off is sharpest. Camera monitors and pendant alarms each ask the resident to accept a lens in the room or a device on the body, and pendants only help when worn. Radar removes both requirements and adds activity recognition on top of presence, which is what the Pro variant is positioned around. The two-SKU split also shows where Aqara expects volume: the $79.99 model is the consumer product, while the Pro variant addresses care providers and families arranging monitoring for a relative. ## Why this matters At $79.99 with Matter and Thread built in, the Aqara FP400 puts presence data once reserved for camera systems or wearables into ordinary smart-home budgets. The Pro variant shows Aqara is aiming the same radar hardware at care providers, not only at automation enthusiasts. For buyers, the practical gain is a sensor that cannot capture an image and still slots into whichever ecosystem the household already runs. The open question is how much of the spatial detail Aqara exposes beyond its own hub layer, since that part remains outside what Matter standardises. ## Related Articles - [Ugreen HomeAgent Combines Local AI, Camera Storage and Matter in One Hub](https://bytevyte.com/ugreen-homeagent-combines-local-ai-camera-storage-and-matter-in-one-hub/) - [Standard WiFi Routers Can Now Identify People Through Walls With High Precision](https://bytevyte.com/standard-wifi-routers-can-now-identify-people-through-walls-with-high-precision/) - [Google Launches Fitbit Air as a Minimalist Screen-Free Health Tracker](https://bytevyte.com/google-launches-fitbit-air-as-a-minimalist-screen-free-health-tracker/) ✔Human Verified --- *Researched and cross-referenced against primary sources by the Bytevyte editorial team.
