I have several unused Aeotec ZW097 Dry Contact Sensors that I found can detect a water leak and have the bonus of allowing easy use of custom probes such as the ones I made for my 2 HVAC water pans. The issue is that the options to invert the status reported by the sensor doesn’t appear to work.
First of all, I tried to change the “Notification Type” to “Water Alarm” but the sensor stops reporting status and if I recall correctly it adds new entities but they do not do anything. Most of my testing has therefore been done with the default “Access Control” type.
I currently have defined a new device_class of “moisture” to make the sensors appear as leak sensors, and that works fine. However when the contact is open, it says “Wet” and conversely, it says “Dry” when the contact is closed.
On another Aeotec door/window sensor I had to change “Invert Binary Report Value” to invert the open/closed status.
That sensor is also set to “Report Type to Send: Binary Sensor CC Report” so I tried that on this one too, but no combination I tried worked.
What am I missing? I would rather not use a template, etc to do it on the front-end if the sensor suppors inverting the status on the firmware level.
EDIT: Most of my testing was done AFTER I customized the sensor with the new moisture device_class in case it matters.
EDIT2: The engineering specifications document is attached on the page linked below (a direct link did not work):
EDIT[n+1]: In all, it would appear that the sensor is already inverted given the tables above indicate the sensor reports WET when ON (closed contact), but both my sensors report WET when OFF (open contact). I may have inverted them in their previous use… not sure, if which case it may mean that the configuration is not sticking. I tried doing it from Node Red and while the Configuration tab reflects the change, it still does not invert the state reported.
