We are adding water logging in firmware 2.1.1 and will show the data next to the zone runs in the table view.
I will also consider plotting this data graphically and want to also use this data to calculate water savings when using automated weather adjustments.
In regard to the actual weather data, logging all of that can become quite a bit of data and also make it hard to read. For the most accurate results, use the weather station selection tool available in the edit options page (location icon next to the input box).
