Not so fast. This is not good. Getting too many notifications.
I'm now testing with Raise check to use this variable instead:
[rain0total-sum60=in.2]
So I now have:
Raise: [rain0total-sum60=in.2] > 0
Clear: [rain0total-sum60=in.2] == 0
Then I'll only be notified on the beginning of every rain event, defined as rain starting to fall separated by more than 60 minutes of no rain.
