What to Avoid
- Mounting Aqara Spatial Multi-Sensor FP400 where HVAC vents or fans sweep the detection field — constant false occupancy.
- Expecting whole-home coverage from one sensor without planning corner height and furniture occlusion.
- Pairing Aqara Spatial Multi-Sensor FP400 before your Thread border router or hub firmware is current.
- Using pet-heavy rooms without tuning sensitivity — read owner threads for your mount height.
Integration and Daily Use
Aqara Spatial Multi-Sensor FP400 only pays off when Aqara Spatial match your primary hub. Plan local control through Depends on primary platform before you mount hardware permanently.
