Tools & Requirements

Step-by-Step Solution

1

Audit placement

Check for HVAC vents, sunlight, or reflective heat sources.

2

Filter automation logic

Use occupancy timing/secondary checks to reduce false triggers.

3

Run validation window

Monitor 24h after placement/sensitivity adjustments.

Quick Solutions

Reposition sensor
Adjust sensitivity/automation filters
Validate with controlled test window

Still having issues? This is usually the deeper cause below.

If the sensor still misses events after repositioning, check whether a scheduled 'home' or 'away' mode is overriding the sensitivity setting silently.

Pro Tip

Sensor placement quality often matters more than automation complexity.

Real-World Insight

This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.

What Usually Goes Wrong
  • Placement near heat source
  • Sensitivity too high
  • RF/environmental noise
