The smart home world keeps evolving toward greater convenience and dependability, and Aqara’s new Presence Multi-Sensor FP300 seems like a meaningful step in that direction. It promises up to a three-year battery life, which, for many, might finally solve the long-standing issue of having to rely on wired sensors for accurate presence detection. The FP300 manages to stay entirely cord-free while maintaining the precision of millimeter-wave (mmWave) radar technology. This longer battery life also gives users more freedom to place it anywhere around the home, making it easier to set up smart automation systems both in India and across the globe.
Key Takeaways
- The Aqara FP300 is a battery-powered presence sensor that runs for up to three years using the Zigbee protocol.
- It combines PIR (Passive Infrared) and mmWave radar sensors for more accurate presence detection.
- The device includes five key functions in one unit: presence, light, temperature, and humidity sensing.
- It supports both Zigbee and Thread protocols, working seamlessly with Matter-enabled smart home ecosystems.
- The FP300 uses two replaceable CR2450 batteries for easy maintenance.
Dual Sensing Technology for Energy Efficiency
Conventional mmWave sensors are known for their ability to detect even subtle human movements, but they tend to consume quite a lot of power. Because of that, they usually need to be plugged in, as seen with Aqara’s earlier model, the Presence Sensor FP2. The new FP300 tackles this limitation by taking a more efficient approach with its dual-sensing design.
In simple terms, it uses both a standard PIR sensor and a 60GHz mmWave radar. The PIR sensor detects initial motion, which then activates the mmWave radar only when needed. This teamwork greatly cuts down on how long the radar has to run, which in turn helps preserve battery life. The FP300 is powered by two replaceable CR2450 coin cell batteries.
Thanks to this smart energy-saving setup, the sensor can last up to three years when connected via Zigbee. If users prefer the newer Thread protocol, which connects directly to Matter controllers, they can expect around two years of battery life instead. Of course, these numbers are based on controlled lab conditions that assume about four hours of presence detection each day, along with regular environmental readings. Actual performance might differ slightly depending on individual usage patterns or settings.
Beyond Basic Detection
The FP300 isn’t just another motion sensor. It’s a full-fledged five-in-one multi-sensor that goes beyond basic presence detection. Alongside PIR and mmWave, it also tracks light levels, temperature, and humidity, all in one compact unit. This combination allows it to provide comprehensive environmental data, opening up possibilities for more intelligent home automation setups.
For example, it can automatically turn on the lights only when someone is present and the ambient light is below a certain brightness level. That kind of automation doesn’t just add comfort, it genuinely helps conserve energy.
Aqara also designed the FP300 with compatibility in mind. It works across major smart home platforms like Apple Home, Google Home, and SmartThings, thanks to its support for the Matter standard. While the Thread protocol enables direct Matter integration without the need for an Aqara hub, connecting the sensor to an Aqara Zigbee hub unlocks a broader range of features through the Aqara Home app. It’s a flexible setup that lets users decide whether to expand their existing system or start fresh.
Physically, the FP300 is compact, measuring just 42 × 42 × 50 mm. It includes a magnetic, adjustable bracket that makes installation surprisingly easy, whether on walls, ceilings, or tucked neatly into corners. There’s no need for drilling or running wires, which makes it an appealing upgrade for anyone experimenting with smart home technology.
Overall, the FP300 feels like a small but significant step forward. It shows that advanced sensing does not have to come with the hassle of cords or constant charging. As smart home devices continue to evolve, it’s perhaps a glimpse into where the industry is headed, toward smarter, more independent technology that works quietly in the background for years at a time.
Related FAQs
Q. What is the difference between a motion sensor and a presence sensor?
A. A basic motion sensor uses PIR (Passive Infrared) to detect movement, like someone walking into a room, but it fails to detect a person sitting or sleeping still. A presence sensor, like the FP300, uses advanced mmWave radar to detect subtle movements, such as breathing or typing, confirming if a person is present even when they are completely still.
Q. Does the Aqara FP300 require an Aqara hub to work?
A. No, not strictly. The FP300 supports Thread and can directly connect to any Matter controller (like certain hubs from Apple, Google, or Samsung) without an Aqara hub. However, you need an Aqara Zigbee hub to access the maximum three-year battery life and all advanced settings and exclusive features within the Aqara Home app.
Q. What is the expected battery life of the FP300 in different modes?
A. The Aqara FP300 can achieve up to three years of battery life using the Zigbee protocol. If you use the Thread protocol for Matter compatibility, the battery life is rated for up to two years. Both estimates use two replaceable CR2450 batteries.
Q. What type of data does the FP300 collect?
A. The FP300 is a 5-in-1 sensor. It collects data on human presence (stationary or moving), ambient light levels, room temperature, and room humidity. This combined data can be used for detailed and accurate home automation routines.
