I'd like the Ranmachine dashboard to track gallons of water used. Using the Flume water system https://flumewater.com/ I know the exact water flow per minutes for each of my irrigation zones. Prior to this meter, I used an inline mechanical water flow meter to gauge approximate flow. 

Since Rainmachine knows the exact watering time of each zone over time, water by day, month, year, zone, etc. would be easy to present using tables, graphically, and allow CSV export. 

With the ever increasing water shortages in the Western United States, knowing one's usage is more important than ever. Being able to see irrigation water use against  a water bill may allow users to make better  informed decisions about landscaping and to know when it is time to consider re-planting an area that is consuming large amounts of water. 

I look forward to comments and consideration for these features enhancements in the future.   -Brad
