I have a related problem with these Ecolink sensors. I have one on a water heater in an unheated closet and the Freeze Alarm notification came but it would not clear for over three weeks. Ecolink suggested trying to use a water test to activate the water notification and that notification came but now I have the LEAK DETECTED ALARM and the LEVEL DROP ALARM with showing on and I have not been able to clear them. I've tried excluding them and re-adding them and removing the battery but no success. After three weeks, I did try a program to wake the sensor and then query the Notify Sensor and it cleared the FREEZE ALARM, but, I don't know if the query worked on the device cleared on it own.
Does anyone know how to clear the notifications on these devices? I have not gotten an answer from Ecolink. it doesn't do any good if the FREEZE ALARM only works one time.
