@ronogg, I'm sorry to hear you're running into the same issues with your Flex schedules. We never like to hear of the Iro using more water than it needs to.
Just curious, did you complete the zone setup process by answering 5 questions for each of your zones? The Iro needs to know the vegetation you're watering, soil type, solar exposure, nozzle type and slope in order to recommend proper watering times for each of your zones. Sometimes the recommended watering times might be longer than you previously watered -- this is usually due to either 1) the root zone depth of the default vegetation setting versus your actual root zone depth, or 2) the precip rate of the default nozzle setting might be incorrect. The good news, these are both easy to change and I'd be happy to help you review your zones if you're up for spending some time doing so
We understand and are here to help. We're learning every day about way to make the zone & scheduling process easier and less daunting. The Iro crunches countless data points in it's attempt to recommend the best watering schedule possible for your lawn. Unfortunately, if some of these data points are wrong, it's reflected in the schedule generated. If we think about it from the auto industry, the Iro out of the box is like a brand new tire (minus the new tire smell) and although it could be mounted on a wheel and installed on your car, it rides much better with a quick balancing otherwise vibrations will likely exist.
Please remember, if we cannot setup your watering schedules to your preference, we will stand behind the product if you wish to return it.
Let me know how I can help with configuring your zones and/or schedules. I like to nerd out on watering times
