haroldunger Posted September 7, 2013 Posted September 7, 2013 Apparently, the sensor is a momentary sensor. If it is wet, it signals that condition and then immediatley returns to the dry mode. Can it be placed into a latching mode showing a wet condition until it is dry?
LeeG Posted September 7, 2013 Posted September 7, 2013 The Leak Sensor has no latching mode. If the conductivity of the leak is sufficient the Leak Sensor will remain in Wet mode. My water comes from a community well filtered through a whole house filtering system. It is common for the Leak Sensor to cycle in this water until sitting in about 1/16" of water. Even at that depth it does cycle infrequently. From the number of users who report similar situations it seems this is "normal". I suspect the more pure the water the less the conductivity factor and thus more cycling is possible. The effect of the cycling can be reduced by using a Wait in the Program monitoring the Leak Sensor.
haroldunger Posted September 7, 2013 Author Posted September 7, 2013 My "domestic" household water comes from a well and it highly filtered and softened. The sensor notices the water and then immediately turns off. There is also other well water that is not conditioned and may contain iron that is used for the water source heat pumps. I guess that conductivity would be greater. Would the sensor stay on under those circumstances? How does one use a "wait" in the program. I merely have the sensor send me an email/text advising of the sensed leak. I really cannot verify if the leak has subsided or remains an issue. When using the filtered water and I look at the log, I see that the sensor is reporting a dry condition immediately after the leak. At this point I am not able to test the unfiltered water to see the result there.
LeeG Posted September 7, 2013 Posted September 7, 2013 What is the objective regarding the notification? Send an email every hour, once a day, need to know the requirement. I suspect the unfiltered water would provide a more solid Wet detection. I have an outside water connection that is supplied before the filtering system. No need to filter water to wash the car. It does cause the Leak Sensor to cycle slightly less but it is not absolute. The initial 'damp' condition with the unfiltered water still allows the Leak Sensor to cycle. We actually have good well water unfiltered. A state University runs tests periodically. I would think high iron content would make the water more conductive. Regardless of the water situation there is no latching function in the Leak Sensor so any smoothing out of the Wet/Dry indications have to be done with ISY Programming.
haroldunger Posted September 7, 2013 Author Posted September 7, 2013 Send an email to me if and only if there is a leak. It's a confirmation to me of the water situation in the equipment area in the basement of the house. Will be installing hard wired water sensors to automatic shutoff valves, power to pumps and notification to alarm company.
LeeG Posted September 7, 2013 Posted September 7, 2013 Cannot verify the Leak Sensor will never false. Mine has not but it is an electronic device. To get a single email issue a Disable for/in the Program sending the email. It will be necessary to manually Enable the Program. Or a Wait can be coded after the Notify for say 24 hours and then issue an Enable for the Program to again get emails after 24 hours if the Leak Sensor continues to signal Wet.
haroldunger Posted September 15, 2013 Author Posted September 15, 2013 According to SmartHome, the leak sensor should be installed manually. I did so and the unit kept reporting a wet condition when wet. Seems as if that has solved the problem...hopefully!
