Aqara Vibration and Light Sensors Not Detecting

Aqara offers specialized sensors including the Vibration Sensor for detecting movement/tilt and the Light Sensor T1 for measuring illuminance. The LED Bulb T1 provides Zigbee lighting. This guide covers detection and control issues.

Vibration Sensor Not Detecting

Symptoms

  • No vibration events triggered
  • Only detects strong impacts
  • Tilt not registering

Solutions

  1. Adjust sensitivity - In Aqara Home, set sensitivity to low, medium, or high.
  2. Mount securely - Sensor must be firmly attached to the object being monitored.
  3. Orientation matters - Tilt detection requires specific orientation. Note the up arrow.
  4. Battery check - Low battery affects sensor responsiveness. Replace CR2032.
  5. Detection types - Sensor detects vibration, tilt, and drop. Each can trigger separately.

Light Sensor T1 Issues

Symptoms

  • Lux readings stuck
  • Not triggering automations
  • Values seem wrong

Solutions

  1. Placement - Position facing the light source you want to measure, not in shadow.
  2. Reporting threshold - Updates when lux changes significantly. Static light = fewer updates.
  3. Automation thresholds - Set specific lux values in automations (e.g., below 50 lux for dark).
  4. Battery - Replace CR2450 battery if readings become erratic.

LED Bulb T1 Not Responding

Symptoms

  • Bulb won't pair
  • Commands delayed
  • Color/temperature wrong

Solutions

  1. Reset bulb - Turn off and on 5 times quickly (2 seconds each) until bulb blinks.
  2. Zigbee hub required - Pair to Aqara Hub or compatible Zigbee coordinator.
  3. Pairing distance - Keep within 10 feet of hub during pairing.
  4. Tunable white - T1 is tunable white only. Cannot produce colors.
  5. Firmware update - Check Aqara Home for bulb firmware updates.

Sensor Pairing Issues (All)

Symptoms

  • LED doesn't flash
  • Hub can't find sensor
  • Previously worked but lost connection

Solutions

  1. Factory reset - Hold reset button (use pin) for 5+ seconds until LED blinks.
  2. New battery - Always use fresh battery for pairing.
  3. Close proximity - Stay within 10 feet of hub during pairing.
  4. Remove and re-add - Delete sensor from hub and pair as new device.
  5. Zigbee mesh strength - Add powered Zigbee devices to improve network reliability.

HomeKit and Automation

Symptoms

  • Sensor events not in HomeKit
  • Automations not firing
  • Light level not updating Home

Solutions

  1. Via hub only - Sensors expose to HomeKit through Aqara Hub.
  2. Sensor exposure - Verify each sensor is set to appear in HomeKit in Aqara settings.
  3. Vibration in HomeKit - May appear as motion sensor. Use Aqara automations for tilt/drop.
  4. Lux automations - Create light-based automations using lux values in conditions.
