Battery-powered SuperLink sensor that detects water leaks, temperature, humidity, and ambient light.

 US Model - operates on 915.6–927.6 MHz.

The sensor is equipped with multiple leak detection points:

  • Flood detection: Two sets of contact points on the bottom of the device sense the presence of standing water.
  • Drip detection: A dedicated set of contact points on the top of the device detects leaks from above, such as dripping pipes or condensation.
  • External probes: A 3.5mm port allows connection of compatible third-party leak detection probes for expanded coverage.

Customised notifications for leak or out-of-range events can be configured in Alarm Manager. Once configured, UniFi Protect instantly sends out a push notification or webhook and logs the event in the dashboard.

The sensor normally operates in a low-power sleep mode, but pressing the function button temporarily wakes it up and forces it to synchronise with the SuperLink Gateway. When pressed, the sensor is also highlighted in the devices page of UniFi Protect making it easy to identify the device.
