Hi Mike,
The ideal soil moisture level depends on your plant type. For example, we recommend set moisture low as 50% and high as 80%, which means when the moisture level is higher than 80%, the next watering will be skipped.
For grass, we recommend set moisture low as 70% and high as 90%. In average, 80% for your zone is fine.
Thanks,
