So nothing ran yesterday afternoon as expected. Then this morning, nothing ran at all.
Didn't work for me. This is exactly my situation. Forecasted rain yesterday, didn't happen, so replace with actuals and water the next today ie. today. No joy.
I'm guessing that is because today is forecasted to rain again. This is not unusual. We have thunderstorms every day and so there is always a 'chance' of rain. It is rarely a 0 projection.
Because Rachio doesn't actually track this continual loss, it is assuming I'm at the allowed depletion. Whereas I'm continually losing moisture and now well below my allowed level (actuals).
I know I could manually add water to get back to the allowed depletion, but this would not help, as Rachio would add it to the depletion level, not current level. For example, I manually add a quarter inch. I should now be at 0.03, Rachio would show +0.25. (side note: the ability to manually water and optionally NOT count it would be helpful).
I don't think it does. If I look at the graph and table for observed results, it assumes I had absolutely no moisture loss between 7/21 and 7/22 when it was 99F here yesterday and dry.
And even I receive the predicted precipitation later today, it will not take me up as high as Rachio is measuring (it has to replenish yesterday's loss that Rachio is not capturing).
Here is the argument for allowing negative values. Using your gas tank analogy, I allow depletion to half a tank. Yet if it dips below half a tank for any reason, I need to track that, as I'll need to add more than half a tank to get to full again. By flooring the calculation at exactly half a tank, I'll add a half tank and think I'm full when that is not true.
