Aqara Presence Sensor FP2 Setup Guide

Aqara Presence Sensor FP2 - Setup Guide

This walkthrough explains how to unbox, mount, power, and configure the Aqara Presence Sensor FP2 using millimetre-wave radar for whole-room presence detection, zone mapping, and multi-platform smart home integration.

Tools required:

  • Small Phillips screwdriver (for wall or ceiling bracket fixing)
  • Drill with masonry or wood bit (only if using screw-mount installation)
  • Spirit level or measuring tape (to confirm mounting height and alignment)
  • Pencil (to mark drill or adhesive positions)
  • Cleaning cloth (to prepare surface for adhesive mount)
  • Stepladder (for ceiling installations at 2.5-2.8 m height)

Applications required:

  • Aqara Home app (iOS or Android) - primary configuration app
  • Apple Home app (optional, for HomeKit integration)
  • Amazon Alexa app (optional, for Alexa integration)
  • Google Home app (optional, for Google Home integration)
  • Home Assistant (optional, for advanced local integration)

Before you begin:

  • Ensure you have a 2.4 GHz WiFi network available - the FP2 does not connect to 5 GHz networks.
  • Have your WiFi SSID and password ready.
  • Decide the mounting location. For general presence detection, a wall or corner mount at 1.5-2 m is typical. For fall detection, ceiling mounting at 2.5-2.8 m is required.
  • Ensure the mounting area gives a clear line of detection across the intended coverage zone (up to 40 m²).

Step 1 - Unbox and identify components:

  • Remove the FP2 sensor, USB-C cable, power adapter, mounting bracket, adhesive pad, and screws from the box.
  • Check the quick start guide for the QR code used during pairing.

Step 2 - Power the sensor:

  • Connect the USB-C cable to the FP2 and to the supplied USB power adapter.
  • Plug the adapter into a standard mains socket. The sensor is low-voltage USB-C powered, so no electrical wiring is required.
  • Wait approximately 30 seconds for the indicator light to begin flashing, indicating pairing mode. If it does not flash, press and hold the reset button on the rear for 5 seconds.

Step 3 - Install the Aqara Home app and create an account:

  • Download Aqara Home from the App Store or Google Play.
  • Register or sign in, and set your region correctly - region cannot be changed later without a factory reset.

Step 4 - Add the FP2 to Aqara Home:

  • In the app, tap the + icon and select Add Device.
  • Choose Presence Sensor FP2 from the sensor list, or scan the QR code on the device or quick start guide.
  • Confirm the indicator is flashing, then follow the prompts to enter your 2.4 GHz WiFi credentials.
  • Wait for pairing to complete - the indicator will turn solid once connected.

Step 5 - Mount the sensor:

  • For wall or corner mounting, attach the bracket using the adhesive pad on a clean, dry surface, or secure with screws for a permanent fix.
  • For ceiling mounting (required for fall detection), fix the bracket at 2.5-2.8 m height with screws. Fall detection covers a 2 m radius directly below the sensor.
  • Clip the FP2 onto the bracket and adjust the angle so the front face is aligned with the area to be monitored.
  • Route the USB-C cable neatly to the power adapter.

Step 6 - Configure detection zones:

  • In Aqara Home, open the FP2 device page and select Zone Settings.
  • Allow the sensor to complete an initial room scan - remain still or leave the room briefly if prompted.
  • Draw up to 30 zones on the room map (for example, sofa, desk, doorway, bed).
  • Assign names to each zone for use in automations.

Step 7 - Enable additional features:

  • Enable Fall Detection if the sensor is ceiling-mounted at the correct height.
  • Enable the Light Sensor to allow brightness-based triggers.
  • Configure Multi-person Tracking if you need to detect up to 5 individuals; performance is optimal with 3 or fewer targets.

Step 8 - Integrate with other platforms:

  • HomeKit: In Aqara Home, open the FP2 settings and select HomeKit. Scan the generated HomeKit code with the Apple Home app.
  • Alexa: Open the Alexa app, enable the Aqara skill, sign in with your Aqara credentials, and discover devices.
  • Google Home: Open Google Home, add a device, choose Works with Google, and link the Aqara account.
  • Home Assistant: Use a supported Aqara integration to expose zones and presence entities.

Step 9 - Create automations:

  • Use presence in specific zones as triggers - for example, turn on a desk lamp when the desk zone is occupied.
  • Combine zone presence with the light sensor to only trigger lighting when ambient brightness is low.
  • Local automations configured in Aqara Home will continue to function during temporary internet outages.

Notes:

  • Matter support is listed as planned - availability is not specified at time of setup.
  • The FP2 is IPX5 rated, making it suitable for bathrooms, but the USB power adapter must remain in a dry location.
  • No hub is required for standard smart home integrations.
