Why customize Aqara Presence Sensor FP2?
Aqara Presence Sensor FP2 gives your software a physical input. Your Home Assistant host uses the paired sensor entities. The linked documentation establishes a control route; the project ideas below are suggestions, not projects we have personally built or tested.
A good fit for
A desk-zone presence routine.
Not the right fit for
A guaranteed plug-and-play result without the listed setup or accessories.

Getting started
- 01
Confirm the exact model
Match the hardware label and bundle to the linked documentation. FP2, constant USB power, 2.4 GHz Wi-Fi, Aqara app for configuration and Home Assistant.
- 02
Prove the documented connection
Follow the original guide and run its smallest supported example before asking an agent to extend it. Pairing and zone setup require care; the device cannot be paired to two independent HomeKit controllers at once. Radar zones can mis-detect presence. Do not rely on a hobby automation for emergency fall detection.
- 03
Build one useful behavior
Start with a desk-zone presence routine. Add logging, sensible timeouts and a manual off switch. Your Home Assistant host uses the paired sensor entities.
Setup & technical references
Starter prompt
Help me plan a desk-zone presence routine using Aqara Presence Sensor FP2. Read https://www.home-assistant.io/integrations/homekit_controller first. Confirm my operating system, exact model, firmware and required accessories. Use only documented capabilities. Start with the smallest reversible test and ask before moving hardware, flashing firmware or changing credentials. Pairing and zone setup require care; the device cannot be paired to two independent HomeKit controllers at once. Radar zones can mis-detect presence. Do not rely on a hobby automation for emergency fall detection. Keep secrets out of public code.
Confirm your exact hardware before running device-changing commands.
