Rachio can skip a watering if it has rained more than the set threshold. However, if it rains slightly less than the threshold, it would be useful if the watering day schedule could be slipped back 1-2 days.
Alternatively, there just could be a scheduling option on the app to slip the existing in one day increments (or pull the schedule in if it looks hot).
I realize this would not work for those users who have day of week watering restrictions.
