Product Description

The upgraded ET Master 4th Gen is ImoLaza’s latest smart sprinkler controller for demanding high-end residential applications. Loaded with innovative capabilities like state-of-the-art offline, valve, flow monitoring and smart alerts, it‘s a top choice for high-end irrigation projects.

With other add-on smart options like hyper-accurate local weather systems and superior Hardware, the ET Master 4th Gen’s possibilities are all but limitless.

Overwatering or underwatering negatively affects plant health, soil quality, and water conservation. However, determining how much water is lost to evapotranspiration and deciding when and how much to water is a challenge for any homeowner, even seasoned gardeners. Traditional methods relied on guesswork, while other sprinkler controllers depended on sensors or historical ET data. Fortunately, ImoLaza’s Real-Time ET algorithm automates precise irrigation, providing a smarter and easier watering solution.

ImoLaza’s Real-Time Evapotranspiration (ET) Technology represents the most advanced and precise irrigation method available today. With ImoLaza, there’s no need for additional tools like soil moisture meters, personal weather stations, or rain sensors. The system seamlessly handles complex calculations, making smart watering decisions based on the actual conditions of your lawn and hyper-accurate local weather data. This intelligent system considers multiple variables, including plant types, sprinkler types, soil types, sunlight exposure, slope, and real-time weather factors like air temperature, humidity, wind speed, sunlight intensity, and precipitation. By calculating how much water is depleting from the lawn each hour and determining how much water to apply to maintain the plant-soil-water balance, ImoLaza provides a key factor that professionals use in determining an effective irrigation schedule. This approach sustains plant health and avoids water waste due to overwatering. ImoLaza ET Master reacts to unexpected weather events with a level of detail and precision unmatched by traditional methods, automating the entire process. It automatically generates preacise watering durations and scientifically adjusts the watering frequency daily, ensuring your lawn receives exactly what it needs.
