My Sensor is Offline. What Should I Do?¶

(Applies to Bluetooth LE Sensors and LoRa Sensors)

Part A: General Diagnostics¶

If you're on-site, we recommend checking these steps sequentially:

Check Hub status¶

→ Determine if sensor offline relates to Hub issues

Verify sensor battery¶

Press setup button for 1s
Check for brief blue LED flash
Low battery? Use included adapter/cable to recharge or replace batteries

Reposition sensor¶

→ Check if distance from Hub causes disconnection
- Place Hub and sensor elevated in same space
- Avoid obstacles and signal interference
- Monitor real-time signal level:
H5 >>> Sensor App >>> Select sensor >>> Press encoder twice >>> View signal level

Software/hardware failure¶

If sensor remains offline when placed near Hub:
→ Contact us
→ Provide sensor SN/name for further support

Part B: Advanced Diagnostics¶

LW1 Sensor Advanced Troubleshooting Solutions

LW1 Sensor Offline Diagnostics¶

Button Operation: Single Press
Function: Test the communication status between the sensor and Hub (gateway).

No Beep¶

Symptom: LED flashes, but no beep sound.

Diagnosis 1: If the device has not completed setup, this status is normal. Please add the sensor in the App first.

Diagnosis 2: If the device is already set up, this indicates communication failure with the gateway. Please check the gateway status or distance.

No Light¶

Symptom: Indicator light does not turn on, and there is no beep sound.

Diagnosis: Power failure. Please check and try replacing the battery.

Normal Status¶

Symptom: Indicator light flashes and emits a beep sound.

Conclusion: The sensor is communicating normally with the gateway.
