Hey JIMMYFWALKER, this is how Smart Watering is intended to work and one of the many ways it reduces water use. It will water multiple times a day for shorter durations to prevent water run-off.
Many homeowners run their sprinklers for too long creating water run-off. For example, a home owner could program the timer for 20 minutes, but the soil can only take in so much water. Let’s say it takes in the first 10 minutes. The rest of the water isn’t being absorbed by the soil, creating run-off.
If you water for shorter durations, it allows the soil to absorb the water and use it. By the time it runs again, the soil will have more room for more water.
