ImoLaza Ultra Controller Review: A Smart Sprinkler Upgrade Worth Making

Introduction

Replacing an aging sprinkler controller is one of those home upgrades that quietly improves daily life. The ImoLaza Ultra Controller is an eight-zone smart sprinkler controller designed to simplify watering schedules while giving you remote control from your phone. It supports up to eight zones, includes a companion mobile app for setup and scheduling, and can be powered either by an existing 24V AC supply or a new 120V AC connection.

This review covers installation, app setup, scheduling options, and the practical details that matter when deciding whether this controller is the right replacement for your current setup.

Who This Product Is For

The ImoLaza Ultra Controller suits homeowners who want to move away from a basic or frustrating sprinkler timer. If your current controller has limited scheduling options, a clunky app, or a zone that has stopped working, this unit offers a straightforward path to a more reliable system.

It is especially relevant for properties with multiple watering zones. The controller supports up to eight zones, making it a strong fit for larger yards where different areas need separate watering schedules. The ability to control everything from a phone, even when you are away from home, adds convenience for frequent travelers or anyone who wants to adjust watering without walking to the controller.

The included mounting template, wiring guide, and labeled terminals make it approachable for DIY-minded homeowners. If you are comfortable connecting a few color-coded wires and drilling mounting holes, installation is well within reach.

Main Strengths

The ImoLaza Ultra Controller stands out for its ease of installation and setup. The unit accepts either a 24V AC power source from an existing controller or a 120V AC power cord, giving you flexibility depending on your current wiring. Color-coded terminals for the common wire and each zone make the connection process clear.

The companion app is a genuine highlight. After scanning a QR code and installing the app, Bluetooth pairs the phone to the controller, then you connect it to your home Wi-Fi. From there, you can name each zone, attach a photo of the yard area, and specify plant type, sprinkler head type, soil type, and sunlight exposure. Advanced settings let you fine-tune root depth, water application rate, and total zone area.

Scheduling is flexible. You can choose a fixed schedule, a new grass schedule, or an ET smart schedule that adjusts watering based on weather forecasts. If heavy rain is predicted, the controller waters less. You can also set cycle and soak options to break up watering time so water penetrates the soil rather than evaporating. Rain skip, freeze skip, and wind skip settings add another layer of control.

The physical control panel is useful when you do not want to use the app. Four buttons let you select zones and manually start or stop watering. A blue LED ring indicates normal operation, while a red LED signals a short circuit on one of the zones. A CR2032 button cell battery powers the time chip so schedules continue running even during a power outage.

Things to Consider Before Buying

While the ImoLaza Ultra Controller is easy to use, there are a few points to keep in mind. The controller retails for around $160 for the eight-zone model. If you only need a few zones, the company also offers four-zone, twelve-zone, and sixteen-zone versions, so you can match the unit to your property size.

The app setup requires a home Wi-Fi network and a smartphone. If you prefer a controller that works entirely without an app, this may not be the right choice. The button cell battery will eventually need replacement, though the app notifies you when it is low.

Installation requires basic wiring knowledge. While the terminals are clearly labeled, you should take note of which wire connects to which zone before removing your old controller. If you are not comfortable working with electrical connections, professional installation may be worth considering.

Buying Advice

If your current sprinkler controller is unreliable or hard to program, the ImoLaza Ultra Controller is a practical upgrade. The eight-zone capacity gives you room to grow, and the app makes scheduling straightforward. The ET smart schedule is a particularly useful feature for regions with variable weather, as it adjusts watering based on forecast conditions.

Before purchasing, measure how many zones your property actually needs. If you have three zones like the installation shown here, the eight-zone model still makes sense for future expansion. If you have a very large property, consider the twelve-zone or sixteen-zone versions instead.

The ability to control watering remotely is a meaningful benefit. Whether you are on vacation or simply away for the day, you can adjust schedules or run a quick test from your phone. For homeowners who value convenience and reliable watering, this controller delivers.

Conclusion

The ImoLaza Ultra Controller is a well-designed smart sprinkler controller that simplifies installation, setup, and daily use. Its eight-zone support, flexible scheduling options, and intuitive app make it a strong replacement for older, less capable controllers. The physical control panel and LED indicators provide a useful backup to the app, and the weather-based scheduling helps avoid overwatering.

If you are ready to upgrade from a frustrating sprinkler timer, the ImoLaza Ultra Controller is worth a close look. It combines practical features with an approachable design, making it a solid choice for most homeowners.
