Most frequent questions and answers


You can rest assured you are saving water, especially if you let our service dynamically adjust and update your schedule on a daily basis. We are running algorithms, accessing data sources, and doing predictive modeling to make sure that your site and landscape always has the optimum watering plan. We can provide reports for you that show how much you are using, and help you to compare.

Yes, better than Wifi, and we use multiple network providers to ensure you have the best connection option. We have been recognized as “best-in-class” in meeting rigorous network efficiency and compliance standards, typically running at a better than 98% connectivity rate with our Wireless 3G and 4G network partners.

Evapotranspiration (ET) is the sum of evaporation and plant transpiration from the Earth’s land and ocean surface to the atmosphere. We auto-adjust your irrigation schedule based in part on ET, water depletion amounts, plant types, soil composition, rainfall, and forecasts, and water only the amount needed

Municipalities, and other Agencies have been putting in place watering restrictions across the country. If we do not already know about a restriction or a change to one, you can contact us, and we will make sure your water schedules and programs are updated with this information. Our service will then automatically schedule watering to happen only as locally permitted, and with variations in the amount of water applied, avoiding costly fines for irrigating during prohibited days and times, and enabling the healthiest landscape.

That’s okay. We can make a dumb system, or a standard controller smart. We are the only company that has found a way to take over an existing controller, and existing irrigation infrastructure and upgrade it to use our smart irrigation service
benefits. This is one of the reasons we call our service the smartest, and it saves you time, and money.

We gather information from some of the nations best weather providers, and we further analyze it to predict and understand forecasts. We also track the amount of actual rainfall. All of this happens at a level of granularity that is unsurpassed, we call it Hyper-local, as it surpasses the capabilities of typical ‘postal code’ and weather station based systems.
