New user - water usage calculation

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?


@rowdybeans - See -> Drip Emitter Calculator for Precipitation Rate & Area or or


Ok. Thanks. I see my issue was the conversion from litres per hour to mm/hour

How do I reset the water usage?

@rowdybeans - send a note to and they can reset your water usage.
