Sorry. The chart is a 13 month rolling chart, not a 13 month rolling average chart. And it’s a month-to-date (MTD) chart, not a daily value chart.
The blue line is the MTD run time, in hours, of the controller, all zones total except the pool (zone 10). Sample frequency is about once every 10 hrs (it’s labeled on the chart at once every 619 minutes). The chart runs from right to left. The right most ‘point’ is ‘today’ - the left most ‘point’ is exactly 13 months ago to the day.
The green line is just the pool (zone 10).
I measure at the Master Valve terminal, and at Zone 10’s terminal. I algorithmically subtract (internal to the measurement and logging system I use) the pool to produce the blue line, which is thus all landscape watering.
All zones are on Flex Daily - full auto. I don’t touch a thing. That’s the whole purpose of purchasing Rachio IMO.
This is Dallas weather. It’s been unusual enough here this year that it dramatically illustrates how Flex Daily is supposed to work.
The months of May and July were very dry - little rainfall. The chart shows Flex Daily pouring on the water to the landscape - 27 and 31 hours of controller run time in these two months respectively. The other months this Spring/Summer have been very wet - lots of rainfall. Like now, August. The chart again shows Flex Daily immediately responding, this time by cranking down the water a lot. The fact that I’m only at 7 hours MTD so far this month is astonishing. We’ve had a lot of rain this month and the controller is automatically adjusting like it’s supposed to.
There’s another chart I didn’t mention earlier, one that indeed shows the daily watering. It’s at http://www.welserver.com/perl/plot/WEL0343/Sprinkler1.png . It clearly shows that some days are zero-watering days due to earlier rainfall, and other days can be upwards of 4 to 5 hours of water.
(And there’s a third chart that shows minute by minute watering for the past 2 days.)
(The no-watering-at-all period, centered at about 6 months ago (-6 on the x-axis) is simply my exasperation with the controller this past winter. I’m not convinced it’s perfect in freezing weather and/or my incoming weather data wasn’t always good (and I don’t have a freeze sensor connected). After I watered in freezing conditions, lost some sprinkler heads, etc., I just turned off the controller. I’ve learned - gotta have a freeze sensor to absolutely insure a schedule isn’t run for a freezing situations day. I know I can manually change out of Flex Daily mode but that defeats the whole purpose of having an Iro 2. I want to stay in Flex Daily mode 24x7x365 and just not have to remember to do anything with the controller - all year long. And simultaneously have perfectly optimum water usage - not a drop more.)
