I have split my schedule into odd/even days so that I can set the start time in the middle of the night.
I wish Rachio had a start/end times to drive the logic of zones to water within that time window. So each day, it determines which zones would need watering the most and start watering and stops at the end time. There would be no need to split schedules, and Rachio would not need to look 2 or 3 days in a forecast to anticipate watering for a zone. That should reduce watering needs (forecasts are not always reliable), and will get moisture level closer to allowed depletion.
