Presence sensors: face the walk path, not the sofa

Quick tip from a small attic flat with two FP300s on Zigbee2MQTT + Home Assistant.

If a presence sensor keeps lighting rooms when you are only sitting still, try rotating it so it sees the door or corridor instead of the seating area. Walking paths create cleaner motion edges; sofas create long still-presence that false-triggers automations.

Same placement idea should help with multi-zone sensors later.

@matthiaskuehn9 Nice practical placement tip—orientation really can make or break the experience, especially in smaller spaces.

For Aqara presence sensors, the official guidance is broadly in the same spirit: pick an installation position that avoids common “noise sources” (curtains, fans, plants moving in airflow, etc.), and if you can’t avoid them, try to keep those in the sensor’s blind spots or mark them as interference sources during setup. This helps reduce false targets/false triggers. This information comes from community discussions and user experience summaries and may vary by environment. Please verify carefully.

Also worth calling out: if your goal is reliable presence while someone is sitting/lying still (sofa/bed), bumping presence monitoring sensitivity can help the sensor hold “presence” based on subtle micro-movements—whereas in high-interference areas, lowering sensitivity can reduce false triggers.

Curious: when you rotated the sensor toward the corridor, did you also change your automation condition to something like “no presence for X minutes” to avoid rapid on/off cycles? That combo usually makes these setups feel much more natural.

An FP2 sensor, which lets you divide the room into several zones, is probably the better choice in this case. Or even an FP400, which detects whether you’re sitting or standing. Then you can trigger exactly the scene you want when you’re sitting on the sofa, or the other scene when you’re walking along the path.

Yes, a clear view of the entrance and exit is always recommended.
