FP300 in Real Life: How It Changes Everyday Automations

I’ve been testing the Aqara FP300 Presence Sensor in daily use, and I wanted to share some real-world observations—especially around scenarios where traditional motion sensors fall short.

Why FP300 Is Different

Most motion sensors work well for “pass-by” detection, but they struggle in situations where people stay still—working at a desk, reading, or sleeping.
FP300 uses mmWave presence detection, which allows it to detect continuous human presence, even with minimal movement.

In practice, this unlocks a different class of automations.

Practical Scenarios I’ve Been Using

1. Home Office / Desk Setup
Lights stay on while I’m working, even if I’m sitting still for a long time.
When I leave the room completely, the lights turn off automatically—no false triggers, no sudden darkness.

2. Bedroom at Night
FP300 can detect presence without relying on movement, which is ideal for sleep scenarios.
It prevents lights or HVAC from turning off unexpectedly while someone is still in bed.

3. Living Room Zoning
With proper placement, FP300 can help differentiate between “someone is in the room” vs. “the room is empty,” making automations feel more intentional rather than reactive.

Things Worth Noting

  • Placement matters. Small adjustments in angle and height can significantly affect detection accuracy.
  • It’s best combined with time conditions or device states for more refined automations.
  • FP300 shines most in low-movement, long-stay scenarios.

Who FP300 Is Best For

  • Users building advanced, context-aware automations
  • Anyone frustrated with motion sensors turning things off too early
  • Smart home enthusiasts who care about presence, not just movement

Let’s Share Use Cases

I’m curious how others in the community are using FP300:

  • Desk setups?
  • Bedroom automations?
  • Energy-saving scenarios?

If you’ve found an interesting setup—or are still experimenting—feel free to share.
Presence-based automation feels like one of those small changes that quietly makes a smart home feel much smarter.

Thanks for sharing your cases and szenarios!
My favorite usecase is in the bathroom BTW

Great you like this small helper @Jeysine2001

Good call about the office usage. I hadn’t considered that one. I’m often having to turn off the lights in the office because the wife forgot to… or the adaptive lighting is still set on ‘middle of the day’ mode instead of the warmer tone that should be running in the evening.

I forgot that they can detect the moment someone leaves a space instead of delayed like motion sensors. Now, if only I can find a way to have it lock my wife’s computer if she leaves the room too.
