Is the water usage number correct?


Hi, I’m manually running my grass of the first time since setting up my Iro. I ran 1 zone for 4 minutes and it says I used 63 gallons of water. Is that an accurate number? To my knowledge, I don’t see how the system knows how much water is flowing out. I don’t have any sensors of any sort… and 63 gallons seems like quite a bit of water for that.


Water usage is an estimate. 3 factors are zone size, nozzle type, and watering duration.

Generation 2 can use a flow meter, when attached, we will use for exact usage.

The nozzle type and zone size (Advanced Zone Settings) can be both modified in the app to get a more accurate reading.

Here is a little more information on the topic:

If you search the forums for ‘water usage’ you should find some more similar postings, here is one for example.

Hope this helps.



@Modawg2k, if you need your gallon reports reset, shoot the support team an email ( and they’d be happy to reset them for you.

If you haven’t already, measure and update your zone area (square footage) within the advanced settings for each zone.


Hi, I’m trying to calculate the square footage of my lawn sprinklers. Do I measure how far out the water reaches to correctly get the square footage for each zone? I know that my total grass area is about 1300 sq ft but I have 3 zones that overlap each other.


@Modawg2k, here’s an online tool to measure if your tape measure isn’t long enough :wink:

Yep, you’ll want to measure the general overlapping coverage for the heads in each zone.

Let us know if you run into any issues.

Best, Emil
