I removed one of my Dome Leak Sensors from ST and added it to my HE, and HE will occasionally report that this sensor is wet (triggering some RM rules), even though the sensor itself is not giving its sound/LED alarm. This never happened in ST.
If I test the sensor with actual water, it always correctly gives its sound/LED alarm and reports "wet" to HE, then "dry" when I remove it from the water. But at random intervals of hours or days, HE will just report that the sensor has become "wet", even though the sensor itself is clearly not wet and not giving its sound/LED alarm as if it were wet. I can hit "refresh" in HE and press the sensor's button to flash the LED and wake up the device, and the battery level may update, but HE will not update the status to "dry". Similarly, I can take out the battery on the sensor and put it back in, but no "dry" in HE. Only way that I have found to get HE to recognize that the sensor is dry is to set the sensor in water (so it actually does alarm) and then remove it (so it stops alarming).
Has anyone else had anything like this happen? Any solution discovered? Could this be an issue with Z-wave interference, as I have a separate ST Z-wave network still running in the same house?
I will probably try removing, resetting, and re-adding the sensor when I have time, but, no, I haven't tried that yet.
