Here is my next instalment for the Multi Presence Sensor FP300. Attached as usual is the downloadable PDF and as usual, feel free to share with anyone who you think might benefit.
I will be producing more guides soon but I have spent a considerable amount of time producing these (about 16 hours in the last 4 days) so the next batch might be a while.
Hope you all have a great day and enjoy the guide!

Aqara FP300 Multi-Presence Sensor Guide
5 sensors in one device, Thread & Zigbee support, and incredibly smart presence detection.
Overview
The FP300 is one of the most advanced presence sensors Aqara has released — and unlike older presence sensors, this one is battery powered, extremely clever, and designed to give you reliable detection without the usual false alarms or dropouts.
It uses dual PIR and mmWave presence detection, backed by AI learning, so it can detect tiny movements, recognise when you’re still in the room, and avoid triggering when something like a fan or a curtain moves.
On top of presence detection, the FP300 also includes light, temperature, and humidity sensors, letting you build powerful automations without needing multiple separate devices on the wall.
Whether you use Thread mode for direct Matter connections, or Zigbee mode for advanced Aqara features, the FP300 is an excellent upgrade from older presence sensors.
Usage & Reliability

-
AI filters out fans, curtains, small pets, and background motion
-
120° field of view and up to 6m range
-
Battery powered — up to 3 years Zigbee, 2 years Thread
-
Adjustable sensitivity, detection range, and absence delay
-
Disable individual sensors to extend battery life
-
Strong detection even in awkward room layouts
-
Optional ceiling, wall, or corner mounting with multi-axis bracket
-
Zigbee mode unlocks Aqara’s full advanced feature set
-
Thread mode allows direct Matter support without a hub
FP300 Multi-Sensor Breakdown
1. AI-Powered Presence Detection
This is the FP300’s strongest feature.
The dual PIR + mmWave combination means:
-
It knows when someone is in the room, even if they’re completely still
-
It reduces false “no presence detected” events
-
It can handle large rooms (up to 6m range)
-
AI learning improves accuracy over time
Perfect for living rooms, offices, bedrooms — anywhere you sit still for long periods.
2. Ambient Light Sensor
Great for automating lights based on how bright the room actually is.
Examples:
-
Only turn on a desk lamp when natural light is low
-
Automatically brighten/dim ceiling lights throughout the day
3. Temperature Sensor
Helps with heating/cooling automations:
-
Turn on cooling when the room gets too warm
-
Adjust heating based on presence + temperature
-
Maintain comfort without wasting energy
4. Humidity Sensor
Useful for:
-
Bathroom moisture control
-
Running fans or dehumidifiers
-
Monitoring humidity in bedrooms or offices
5. Dual-Protocol Support (Thread + Zigbee)
The FP300 is the first Aqara presence sensor that supports both.
-
Thread Mode - Connect directly to Apple Home, Google Home, SmartThings, Home Assistant (Matter). No Aqara hub required.
-
Zigbee Mode (Recommended)
Unlocks:
-
AI spatial learning
-
Adjustable sensing distance
-
Adjustable absence delay
-
Sensor enable/disable options
-
Full Aqara ecosystem automations
-
More reliable device-to-hub communication
Recommended Settings (Zigbee Mode)
My Personal Tip
When using Zigbee mode, I strongly recommend:
1. Setting the detection distance:
-
Open FP300 → 3 dots → On-Site Configuration → Detection Range
-
Set it to the length of your room for best accuracy
2. Running AI Spatial Learning:
-
FP300 → 3 dots → On-Site Configuration → AI Learning
-
This massively improves responsiveness and reduces errors
This is one of the biggest improvements Aqara has introduced — and few people know about it.
Accessibility & Ease of Use
The FP300 is excellent for accessibility:
For mobility limitations:
-
Automates lighting and heating without interacting with switches
-
Works with extremely subtle movement
-
Can control entire rooms automatically
For visual impairment:
-
Helps automate lighting based on illuminance
-
Works seamlessly with smart speakers
For cognitive or memory challenges:
-
Removes the need to remember to turn things off
-
Can automate comfort, safety, and lighting routines
For neurodiverse users:
-
Helps create predictable, sensory-friendly environments
-
Enables calm lighting transitions based on presence
Practical Scenarios
|Scenario|Use Case|Example|
| — | — | — |
|Presence Based Lighting|Presence-Based Lighting Lights respond to presence|Presence + low lux → Turn on ceiling lights|
|Energy Saving|Turn off lights when empty|No presence 3 min → Turn off lamps|
|Smart Cooling|Maintain comfort|Presence + temp > 28°C → AC cooling|
|Home Office Lighting|Optimised workspace|Presence + dim room → Desk lamp on|
|Night Safety Lighting|Low-level guidance|Presence 1–6am → Warm 10%|
|Humidity Control|Bathroom moisture|Humidity > 70% → Extractor fan|
|Bedroom Comfort|Warm wake-up|Presence + temp < 18°C → Radiator 40%|
|Ambient Adjustments|Adaptive room lighting|Low lux → Brighten T1M/T2|
|Security Monitoring|Detect presence when away|Presence + nobody home → Alert|
|False Trigger Reduction|AI learns environment|AI filters curtains/fans|
|Accessibility Routine|Hands-free control|Presence → Room scene|
|Full Smart Room|Combined sensing|Presence + lux + temp → Full automation|
Aqara Home Automations (WHEN → IF → THEN)

-
Open Apple Home
-
Tap + (top right)
-
Tap Add Automation
-
Select A Sensor Detects Something
-
Choose FP300
-
Choose Presence Detected
-
Add condition → Light Level is Below X Lux
-
Action → Turn On Desk Lamp
-
Save
In Apple Home, the FP300 appears as:
-
Presence Sensor
-

-
Humidity Sensor
Allowing powerful combined triggers.
Tips for Best Use
-
Use Zigbee mode if you want the full Aqara features
-
Always run AI Spatial Learning for accuracy
-
Set detection distance to the room length for best sensitivity
-
Use low absence-delay for dynamic lighting
-
Combine light + presence for excellent energy savings
-
Use humidity for bathroom routines
-
Use temperature to optimise heating/cooling
-
Avoid placing it near reflective surfaces (mmWave can bounce)
-
Keep automations simple but powerful
Final Thought
The FP300 is one of Aqara’s smartest and most flexible sensors yet. With AI presence detection, five built-in sensors, dual-protocol support, and outstanding battery life, it can completely automate comfort, lighting, and energy management in your home.
Whether you’re starting fresh or upgrading from older motion sensors, the FP300 gives you the intelligence and precision needed to fully automate your rooms — exactly the way a modern smart home should work.
