Aqara Presence Sensor FP300

Quick verdict

The FP300 is Aqara's most ambitious sensor yet, combining mmWave presence, PIR motion, light level, temperature, and humidity all in a battery-powered package that Aqara rates at up to 3 years in Zigbee mode and up to 2 years in Thread mode. It speaks both Thread/Matter and Zigbee, so it fits into basically any Home Assistant setup. The big question is whether battery-powered mmWave can match the USB-powered FP2's accuracy. If it can, this is a big improvement for sensor placement freedom.

Standout: Battery-powered multi-sensor combining mmWave presence, PIR, light, temperature, and humidity with Thread and Zigbee support.

Compatibility snapshot

Why it stands out

• mmWave plus PIR plus light, temperature, and humidity, giving you five sensors in one device
• battery-powered on two CR2450 cells, with Aqara claiming up to 3 years in Zigbee mode and up to 2 years in Thread mode, so no USB cable clutter
• supports both Thread/Matter and Zigbee for flexible integration options

Reasons to hesitate

• new product so real-world battery life and reliability are still being proven
• mmWave detection range and zone accuracy may be more limited than the USB-powered FP2
• many sensor readings may not all be fully exposed via Matter yet

Best for

• rooms where you want presence detection plus climate data in a single battery-powered unit
• Home Assistant users who want a versatile sensor without running a USB cable

Avoid if

• you need proven, battle-tested presence detection. The FP2 has a longer track record
• you want the most granular zone-based detection. USB-powered sensors still have more power budget for that

Privacy and local-control notes

Fully local via Matter over Thread or Zigbee. No camera or audio. Multiple sensors on board but all report simple environmental data.

Home Assistant support: supported · integration path: matter / zigbee2mqtt / ZHA.

Buying reality check

Price notes: Mid-range pricing is impressive given the number of sensors packed in. The battery-powered form factor adds real placement flexibility.
