Sean,
I have imported your configuration and begun examining the issue. Just for reference, the previous app also reported no watering for today so this isn’t a new issue.
In regard to previous days, you can goto the table log data and see the average watering level for that day (an average of each reply for that day).
Update: By the way, is your water level 0%? Because the current day takes into account the current watering level and if it’s 0% the preview will show no runs whereas any other day will show the set durations. Based on your current export, it looks like the water level is in fact 0%.
