Why isn’t my Sensor showing up in the LeakSmart app now that I’ve paired the Range Extender?
If you just paired or re-paired a Sensor during your Range Extender installation, it may have appeared to connect to the system by exhibiting 3 quick beeps and 5 slow blue flashes, but did not show up in the app. If this is the case, then 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. Pair the sensor by choosing “Add Device” in the LeakSmart app and follow 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, take the sensor to its intended location to detect leaks and re-pair it in that location.
