Smart Protection and Reliability
You’ll appreciate that the controller focuses on preventing failures as much as on saving water. Smart Fault Detection, surge protection, and a real-time clock keep the system running accurately and safely, even when conditions aren’t ideal.
Smart Fault Detection
The controller continuously monitors the electrical and flow behavior in your irrigation system and sends alerts if it detects anomalies. That means you’ll often find and fix issues before they become expensive problems like a burst pipe or damaged valve.
Surge Protection
The included surge protection is designed to guard against lightning strikes and power spikes that could otherwise fry electronics. For outdoor systems connected to long runs or to external transformers, this protection provides peace of mind and potentially long-term savings on replacement costs.
Real-Time Clock (RTC) and Offline Reliability
Because the controller includes an RTC, your schedules remain accurate during short power outages or internet interruptions. You won’t end up overwatering or missing cycles just because your WiFi goes down for a day.
Tailored Scientific & Precision Irrigation
You’ll get granular control over how much each zone receives because the ImoLaza controller factors plant type, soil, nozzle, and sun exposure into its schedules. This precision reduces wasted water and promotes healthier plant growth.
Zone-by-Zone Customization
You can configure each of the 12 zones independently, assigning plant type (e.g., turf vs. shrubs), soil type (clay, loam, sand), nozzle or sprinkler head type, and sun exposure. That ability lets you avoid one-size-fits-all schedules and instead create a plan that matches each area’s needs.
Evapotranspiration (ET) Algorithms
Using ET calculations, the controller figures out how much water is lost to evaporation and plant transpiration and orders watering accordingly. This dynamic approach is more accurate than fixed-duration schedules and adapts automatically to changing weather patterns.
Plant, Soil, and Nozzle Inputs
You get the option to tell the system what you’ve planted and what hardware you’re using. The controller then adjusts run times based on these inputs, so turf with pop-up rotors doesn’t get the same duration as a flower bed with drip emitters.
Smart Skipping & Seasonal Adjustment
If you dislike wasting water, you’ll like that the controller intelligently skips watering during rain, freezing conditions, or when soil is already saturated. Seasonal adjustment also ensures your program changes as plant water needs change through the year.
Weather Skip (Rain/Freeze/Wind)
The system pauses irrigation automatically when local weather sensors or forecast data indicate rain, freezing temperature, or wind that would render irrigation ineffective. That saves water and prevents damage like frozen lines.
Saturation Skip
If the soil moisture is already sufficient, the saturation skip prevents unnecessary cycles. This is especially helpful after heavy rains or in shaded areas where moisture lingers longer.
Seasonal Adjustment
You won’t need to manually retune schedules for spring vs. summer vs. fall — the controller adjusts the baseline watering durations and frequencies based on seasonal patterns. That keeps your lawn healthy without you having to think about it every month.
Smart Control Anytime, Anywhere
You manage everything through the ImoLaza app, which includes free access to premium features so you aren’t paying subscription fees just to get advanced functionality. Remote access means you can change settings from your phone while at work, on vacation, or standing in your yard.
ImoLaza App Interface and Features
The app gives you a clear dashboard with current status, alerts, and one-tap manual runs for zones. You can set schedules, view watering history, and receive system health notifications — the app keeps things simple and functional.
Voice Assistant Integration
If you use smart assistants, the controller integrates with Amazon Alexa and Google Assistant, enabling voice commands for common tasks. You can ask for the status of a zone, start a manual run, or put the system into rain skip via voice control.
Remote Monitoring and Alerts
When the controller detects faults or abnormal conditions, it pushes alerts to your phone so you can act quickly. Remote diagnostics and logs make it easier to troubleshoot or share details with a pro if you need service.
Quick & Easy Installation
If you’re comfortable with basic wiring and following step-by-step guides, the ImoLaza controller is designed for a quick DIY install that usually takes 15 to 30 minutes. You don’t need special tools, and it’s engineered to be compatible with nearly all existing irrigation systems.
Three-Step Setup Process
The manufacturer highlights a simple setup process: mount the controller, connect valve wires and the transformer, and finish WiFi pairing via the app. The clarity of those steps means you can often replace an old controller in a single short session.
Compatibility & Outdoor Installation
It’s compatible with 99.99% of irrigation systems and supports outdoor installation with a weatherproof enclosure. The unit is also suitable for permanent hardwiring if you prefer a secure power connection rather than plugging into an outlet.
Time to Install
Most users can get from unboxing to scheduled watering in under half an hour if wires are labeled and existing hardware is standard. Complex systems with specialized wiring or long runs may take longer, but the controller is intentionally user-friendly.
Performance in Real Conditions
You want a controller that performs when it matters: during storms, heatwaves, and system faults. ImoLaza focuses on three main areas: weather-based skipping, saturation detection, and resilient operation through outages.
How Weather Skipping Works
The controller pulls hyper-local forecast data and uses thresholds for rain, wind, and freezing to automatically suspend watering when needed. This avoids watering during rainstorms, prevents frozen pipes from bursting, and reduces inefficiencies caused by high wind.
Saturation Skip in Practice
Saturation skip evaluates recent precipitation and soil moisture inputs so that you don’t water a zone that’s already fully saturated. If you have areas that hold moisture longer (like shady flower beds), the saturation skip helps maintain balance across the landscape.
Seasonal Adjustment Effectiveness
As temperatures and daylight change, the controller modifies water schedules so your plants neither dry out nor stay waterlogged. This continuous fine-tuning is particularly useful if you travel often or maintain unfamiliar landscapes.
Power, Backup, and Hardiness
System robustness matters because irrigation controllers operate outdoors and are exposed to storms and outages. ImoLaza includes hardware and firmware features designed to keep schedules intact and to protect electronics.
Real-Time Clock (RTC) and Outage Handling
The RTC keeps accurate time when power or WiFi is briefly interrupted, which preserves your programmed schedule. This avoids accidental double-watering or missed cycles after brownouts or ISP outages.
Surge and Over-Voltage Protection
If lightning or a power surge occurs, the surge protection is intended to prevent catastrophic failures that would otherwise leave you without control or requiring expensive replacements. For areas prone to electrical storms, this is a tangible benefit.
Outdoor Durability
The unit’s weatherproof design allows for outdoor mounting without special shelter, and the hardwiring option gives more secure power for permanent installations. These aspects make it viable for both residential yards and light commercial landscapes.
Best Uses and Ideal Customers
You’ll know whether this controller fits your needs based on who you are and what your landscape looks like. It’s a strong fit if you manage multiple zones, want to cut water waste, or run a small landscaping business.
Homeowners with Diverse Landscapes
If you have lawns, flower beds, trees, and drip lines all on the same property, the 12 independent zones let you match schedules precisely. The system makes it easy to save water while keeping different plantings healthy.
Small Landscapers and Light Commercial Use
ImoLaza is built for light commercial applications where outdoor-rated hardware and robust scheduling are required. If you manage small commercial plots, HOA zones, or higher-end residential properties, this controller can scale to meet your needs.
People Who Want Low-Maintenance Automation
If you travel frequently or prefer a “set it and largely forget it” approach, the weather-based logic and RTC ensure the system runs accurately without daily attention. Alerts let you address issues quickly if something goes wrong.

Troubleshooting and Smart Fault Detection Details
If something goes wrong, the system gives you tools to diagnose the issue remotely and take action. You’ll often see the root cause from logs or alerts without having to go inspect every valve physically.
Typical Alerts and What They Mean
Common alerts include valve short circuits, open circuits (broken wire), and abnormal flow or pressure changes suggesting a leak. Each alert type points you toward a different action: checking wiring, looking for broken irrigation lines, or verifying valve operation.
Simple Troubleshooting Steps
When you get an alert, start by reviewing the alert detail in the app, then inspect the affected zone physically: check wiring connections at the controller, test the valve solenoid with a manual run, and look for pooling or soggy areas in the landscape. If you don’t identify the issue, the logs you can share with an irrigation pro speed up service.
When to Call a Pro
If you see repeated shorts, persistent pressure anomalies, or valve hardware failure, it’s often time to engage a licensed irrigation technician. The controller gives you more accurate diagnostics, which usually reduces the service time and cost.

Installation Checklist and Wiring Guide (Practical)
You’ll want a simple checklist before you start to keep installation smooth. These items and steps are typical for replacing an existing controller or installing a new system.
- Turn off power at the breaker or transformer and confirm no live voltage.
- Label each valve wire if not already labeled, or map zones before disconnecting the old controller.
- Mount the ImoLaza unit in the desired outdoor location using provided hardware and weatherproof considerations.
- Connect common wire and zone wires to their respective terminals, and connect the transformer/hardwire per instructions.
- Power up and follow the app-guided WiFi pairing and initial zone configuration.
Following these steps reduces the chance of wiring mistakes and speeds up commissioning.
Tips for Getting the Most Out of Your ImoLaza Controller
You’ll get better results faster if you tune a few things after the basic install. These tips help you maximize water savings, plant health, and the longevity of your system.
- Spend time on initial zone setup: accurately tell the controller plant type, soil, nozzle, and sun exposure for best ET-based decisions. This front-loaded effort pays off in precision watering.
- Use the app’s manual run feature to observe each zone’s coverage and adjust head patterns before relying fully on automatic schedules.
- Check surge protection visually after storms and consider additional surge suppression on the main power feed if your area has frequent lightning strikes.
- If you have areas with different irrigation methods (sprays vs. drip), group similar heads into the same zones to avoid mismatched run times.
- Periodically review watering history and skipped cycle logs to see how often saturation or weather skip prevented watering — this gives insight into over- or under-watering trends.
- Schedule regular seasonal adjustments if you prefer specific deviations from automatic behavior (e.g., slight reductions in late fall).
