Congrats, it has been some time!
If you look in the activity feed all of your events show up there including rain sensor activated/de-activated.
If your weather station has recorded the precipitation and it is over the threshold set for the schedule, it will be skipped.
One hour before the schedule runs you will receive a notification in your events that says if the schedule will run or not based on observed/forecasted precipitation.
Please let us know if you have any other questions.
