Why isn’t my Sensor detecting leaks now that I’ve paired the Range Extender?

If you just installed the Range Extender and the Sensor is no longer working, you will need to perform a factory reset on the Sensor twice.

First, reset the Sensor next to the Hub. To perform a factory reset on the Sensor, open the battery door compartment on the Sensor and hold the pairing button down for 15 seconds. Then, remove the middle battery & replace it, at which time you’ll hear a chirp and the LED will flash rapidly on the top of Sensor. Re-pair the Sensor at this time by choosing “Add Device” in the LeakSmart app and following the instructions.

Once you have successfully paired the sensor, reset it again next to the hub by holding the pairing button down for 15 seconds, then remove the middle battery and the replace the battery. When you hear a chirp and see the LED flash rapidly on the top of the sensor, the sensor will disappear from the sensor list in the app. Take the sensor to its intended location to detect leaks and re-pair it in that location. Once it successfully shows up in the app again, test the Sensor to ensure it’s working by applying a damp cloth to the two metal prongs on the bottom of the sensor.
