New Rachio user here. I setup the Recipe the other day and it created the spreadsheet. +1 for more data here as others have said.
The thing that surprised me was that it did not trigger the recipe when I manually ran a couple of zones in the last few days. I thought it would log this, but it did not. Does the recipe only trigger when a watering scheduled job completes instead of when ANY watering has completed? It would be nice to get a complete log, though perhaps that's what the download CSV provides and I should just be using that?
