Can’t get soil moisture to remain above 80%

Dont get me wrong. Now that I have gone with a Wi-Fi smart controller I wont go back. When I decided to upgrade I was merely looking for a controller that allowed me to remote control it via Wi-Fi and rain skip. Other features were just icing on the cake. With rachio being able to connect to the weather station and to adjust water schedules dynamically, thats awesome. However to use its benefits fully is an excercise of frustration. If it was easy, I wouldnt be on this forum.
