Piston with Only When Condition

#1

I had created a piston to notify me of weather alerts. It has worked fine, except I would get alerts I didn’t care about. I modified it to only send an alert for certain conditions, I hope. What I am not sure about is the ONLY WHEN condition. I don’t want to get an alert for a blank alert which shows up as []. Should this work ok?
The only when checks for the alert to have a length greater than 2.

For some reason the image won’t paste??? It says pasting, but doesn’t show up.

Now trying to delete post until I figure out the image issue, but can’t do that.
Sorry folks.

What you’re doing should work. None of the code inside the “only when” restriction will run unless your alert length is greater than 2. This shouldn’t generate a blank alert… it shouldn’t generate any alert at all when your alert length is 2 or fewer characters.

This problem has been fixed!
