Help when the product does not work

Wireless sensor: Read battery and connection state in the system. For low battery, use the model battery guide and check the battery type and whether it is replaceable. Note new metal objects or other changes near the sensor.

Choose the symptom and check the model scope before following the steps. This is troubleshooting, not a list of confirmed product defects.

General advice — model-specific fault procedure missing.

Door/window sensor: shows open when closed

Applies to: General advice for the sensor type — not a verified procedure for this model. Use the model manual for opening, battery type, testing and settings.

  1. Check that the message concerns the correct door or window. Close it fully and read the current state again.
  2. If the sensor uses a magnet, look for loose, displaced or damaged parts. Correct side and distance depend on the model.
  3. Arrange an open/close test with the monitoring service. Compare the actual position with current system state, not just old events.

Check the result: The correct zone changes between open and closed.

Stop and get help: If the fault persists, let the installer check alignment and any external contact. Do not add a loose magnet or bridge wires.
