I mean, I’m still very new myself so this may not be exactly what you’re looking for.
But if you have a spare robot, I suppose you could always set up an if statement, with the default value as a variable, and the actual value as a secondary variable.
Then, have the robot [display message] if DefValue != ActValue?
The problem is triggering the check; I’m not advanced enough to know how you could get the robot to trigger if a particular value is changed, much less if -any- value is changed.
Though, if they are all numerical values, I suppose an unconventional approach would be to make the Default Value variable a sum of all the default values - or even a concatenation. Then if any of the component pieces were changed, the Actual Value variable would also change, triggering the message?
