I do appreciate the graphs that show total water usage by month & day, but I would also like to see graphs/charts with a breakdown of water usage by zone. I have a flow meter connected to my Gen2 controller and appreciate the more accurate usage data. But when multiple zones run on a single day, it's impossible to determine how much water was used on each zone. In Southern California we have a constant water shortage and need to use it as efficiently as possible. I have used a competing controller in the past that provided customizable graphs with usage by zone, but the competing controller had lots of other problems that caused to choose the Rachio Gen2.
