There are certain times when I have manually started a watering program when I need to hold it temporarily (e.g.: someone is going to take a shower inside the house or other reason) and then restart it at a later time - exactly at the point at which I previously held it. Presently, when I encounter this situation, I have to stop the program entirely, keep track of the point at which I stopped it, then start it again - never being able to restart it at exactly the point as which I cancelled. This latter process is a nuisance.
The iPhone app needs functionality for “Hold Program” and “Resume Program” when selecting an active Water Station within manual watering. This would be added to the current screen selection: “Stop Program,” “Next Station,” and “Cancel”.
