I was excited to read that with firmware 2.3.4 the built in Notifications App supported hub variables. I have been unable to get hub variables to display properly in my notification messages. I am using the same code I use in one of my rules to send out the notification. The notification in my rule works fine and reports the correct value for the variables. The notification from the notification app are not accurate and seem to be the same all the time, as if it was pulling some default value instead. Not sure if this is a bug or if I am doing something wrong. Below is my notification code that I use in both the rule and notification app.
%date% %time% - Bathroom exhaust fan powered %value%: BathroomExhaustFanAutoOn(%BathroomExhaustFanAutoOn%), BathroomExhaustFanManualOn(%BathroomExhaustFanManualOn%), BathroomExhaustFanManualOff(%BathroomExhaustFanManualOff%),
BathroomExhaustFanAutoOnDelay(%BathroomExhaustFanAutoOnDelay%).
