Great idea Frank. In our upcoming release next week, we will have automatic schedule creation and rain delay.
We're pretty excited about the rain delay feature. It will allow you to sleep the system for 24 hours from the time you kick it on. The really cool thing is that the Iro can turn it on itself based on weather. There will be visual indication of it on the home screen.
You can also quickly turn it off if you change your mind or think that the Iro has incorrectly turned it on.
