The Aqara FP300 is a versatile 5-in-1 presence multi-sensor designed to keep your smart home responsive by combining a 60 GHz mmWave radar with a PIR sensor. This dual-technology approach allows it to detect both active movement and motionless presence, meaning your lights won't turn off while you are sitting still reading or working. Along with presence detection, it monitors ambient light, temperature, and humidity to help you automate your environment based on real-time conditions. This compact device measures 42 x 42 x 50 mm and is powered by two CR2450 batteries, which can last up to three years when using Zigbee or about two years in Thread mode. It offers flexible connectivity through Thread, Zigbee, and Bluetooth, making it compatible with Matter, Apple Home, Google Home, and SmartThings. To get it running, you will need either a Matter controller for Thread or an Aqara Hub for Zigbee. Setting up the sensor is straightforward thanks to a magnetic support and multi-axial mounting system that lets you angle it precisely. You can fine-tune its performance through the Aqara Home app using AI spatial learning, radar sensitivity adjustments, and customizable absence confirmation periods. Depending on the specific version, the package includes the sensor and manual, with some models adding a metal plate and screw kit for a more permanent installation.
