RM: java.Math error on new rule


I'm seeing a Java error on a new RM rule I made. Seems weird as it is a pretty simple rule.

Any thoughts?

dev:3912019-01-07 04:59:09.853 pm infoComputer Room Light is active

Here is the rule:


EDIT: Never mind, I see the issue now. Somehow the "Fade over X minutes" value is set to null...

Not sure how that happened! I certainly didn't do that on purpose (not sure it should be able to be done on accident, though either). User error I guess. I've fixed it now.
