How does a Water Leak Sensor work?

The Water Leak Sensor utilizes the conductivity of water. When two probes touch the water simultaneously, a current loop is formed. At this time, the sensor reports the water immersion/water leakage status to the hub, triggering an alarm.

Why does the hub have no alarm sound after detecting water immersion?

Please check whether the alarm switch of the subdevice is turned on in the subdevice list of the app. When not enabled, only message push and logging are available.

Why is the Water Leak Sensor often offline?

1. The device is far away from the hub. Please install the sensor close to the hub. 2. The battery is low, or the battery is dead. Please replace it with a new battery. 3. 915MHz is installed on a metal surface, and the signal is disturbed.

What is the reason for the failure to connect the Water Leak Sensor? How should I reconnect?

1. If the operation is wrong, please re-add the device according to the device adding method.

What is the water level to trigger the alarm?

When the detected water level reaches a height of 2mm, an alarm can be triggered.
