I have a new rachio gen 2 device. I have set the area of my planter box as 6m2 and set up all the settings I think I have right. I have 16 drippers that use 4l of water per hour. After a couple of manual tests, the app is showing 67 litres used. This seems like a lot for about 10 minutes of testing.
Is there a calculation or another setting that I need to add for the correct usage?
