FortrezZ Moisture Sensor

The FortrezZ Moisture Sensor (also known as the original SmartSense Moisture Sensor, but not to be confused with the newer SmartSense Moisture Sensor) is a Z-Wave-based moisture sensor that alerts you when moisture is detected. This indoor-only sensor can identify leaks on the basement floor, under a sink, around the washing machine, or in a bathroom.

For a quick look at the FortrezZ Moisture Sensor and how it could work in your home, check out this video.

Troubleshooting the FortrezZ Moisture Sensor

If the moisture sensor did not connect with the Hub, press its button and observe the LED.

If the LED does NOT light up when pressing the sensor’s button, check the following:

  • Batteries: The batteries may be drained and need to be replaced. Also check that the batteries are seated correctly and that the black battery holder isn't cracked or broken. This could lead to no contact with the batteries.
  • Wiring: Check the wiring inside the enclosure. If any wires are disconnected or broken, the device won't function. Contact SmartThings Support if there is obvious physical damage to the device.

If the LED does light up when pressing the sensor’s button:

  • Range: Make sure the device is close to the SmartThings Hub. This device is particularly sensitive to range issues when connecting for the first time, so place the sensor within 5 feet of the Hub when first connecting the device.
  • Connection with another controller: If there is one slow blink after pressing the button, the sensor is already connected to a controller. See instructions for resetting/removing/excluding your device below (Resetting the FortrezZ Moisture Sensor).
  • LED behavior: For more information about what the LED’s blinks mean, check the manufacturer's manual.
