Aqara Presence Sensor FP2
- Wi-Fi
Verified September 2026
Still the reference mmWave presence sensor for UK living rooms and open-plan kitchens: up to 30 configurable zones across a 40 sqm room (8 m range, 120 degree field of view wall-mounted), so lights never cut out while you sit still. At around £58 it costs roughly £20 more than Aqara's own FP1E, which covers just one zone — pay the premium only if you need per-region control across a large or open-plan space, otherwise the FP1E is the smarter buy. It's mains-powered via USB-C only, no battery, so plan for a socket nearby. Integrates locally with Home Assistant via the built-in HomeKit Device integration over Wi-Fi.
In Home Assistant
| Control | Type | What it does |
|---|---|---|
| Zone occupancy | Binary sensor (per zone) | One occupied/clear entity per zone configured in the Aqara app, since each zone syncs to HomeKit as its own accessory. |
| Overall occupancy | Binary sensor | Aggregate occupied/clear entity for the whole covered area, exposed alongside the individual zone entities. |
| Illuminance | Sensor | Built-in lux sensor, surfaced next to occupancy, so a lighting automation can combine zone presence with a darkness threshold. |
| Zone layout | App-only config | Zone boundaries, interference regions, and sensitivity are drawn and tuned in the Aqara app only; HA can read the resulting states but can't edit the layout. |
| Person count | Unsupported | HomeKit's occupancy service carries no headcount characteristic, so HA never sees a number of people — only which zones are simultaneously reporting occupied. |
Because each configured zone syncs to Apple Home as its own occupancy accessory, homekit_controller mirrors that structure in HA — you get one binary sensor per zone plus a whole-room sensor, not a single aggregate occupied/clear state. There's no headcount characteristic in HomeKit's occupancy service, so multi-person tracking in HA terms just means several zone sensors can read occupied at the same time, not an actual person count. Zone shapes, interference regions, and per-zone sensitivity are all drawn and tuned in the Aqara app and pushed down to the device — HA only consumes the resulting states, it can't redraw zones itself. Community reports flag cross-zone bleed (a zone staying occupied for a few seconds after someone walks through it into the next one) unless you rerun the self-learning routine with fans/pets active and keep sensitivity at low or medium rather than high.
