Would it be possible to add a feature that automatically adjusts the watering start time in relation to the sunrise time? It wouldn’t have to be a daily adjustment, I think a monthly would work fine if that simplifies things. The sunrise is constantly shifting so 6 or 7am in the summer is sunny and in the fall/spring its pitch black.
This is a good suggestion for future enhancement. It’s like my home automation system, where outside lighting is scheduled automatically to be turned on at sunset and off at sunrise, including understanding when or when not daylight savings is in effect.
