FP400 successor to FP300?

I’ve been trying to get a hold of the FP300 for a few months now with no luck and wondering if I should just wait for the FP400. Is the FP400 a direct successor to the 300 or is it replacing one of the wired products?

No, it’s the newer version of the FP2 and the main difference is the FP400 will have Matter and Thread features vs Wifi only.

Hope that helps?

Thanks for clarifying!

Is that really going to be the main difference? Not improved sensors, accuracy, etc?

No, there are several improvements or additional features. I don’t have the complete list at my fingertips at the moment.

They were posted at the Aqara CES event.

  • Multi-person spatial awareness: The FP400 uses mmWave radar and AI to detect multiple occupants in a room and track their movement in real time — including headcount and dwell analytics like how long people stay and how far they walk.
  • Posture detection: Unlike earlier presence sensors, it can distinguish whether someone is standing, sitting, or lying down

Real-time analytics: It provides live person tracking , not just simple motion or occupancy — enabling richer automations and insights for both residential and commercial use

Spatial automation triggers: Because it delivers granular data (position, posture, counts), users can build advanced automations — for example, adjusting lights or thermostat based on whether someone is seated vs. lying down

Hope that helps?

That’s super helpful! Excited for the posture tracking - only turn the lights on when someone is sitting at the dining room table. That would be amazing.
