Weather Intelligence is great, it could be better if it looked back also. It appears to me that weather intelligence looks at the present and the forecast condition for the day. I think another super advantage could be to look back a few days. If I am watering today, did it just rain an inch of rain 2 days ago? I think if would be super helpful if weather intelligence looked backwards at significant rainfall events and muted the current schedule if needed. Maybe skip or just cut it in half or something.
When I look at the details of the soil moisture, it adds moisture based upon precipitation. It seems to me this is the effect that you are asking about. It probably would not cut the time, but rather just increase the soil moisture which will cause a delay in when the next watering happens based upon many factors. Does that make sense or am I misunderstanding?
