With the best smart sprinkler controller, you won’t only be saving time but also money in the long run. As long as you pick the right model for your lawn, lawn irrigation will cease to be a tiring chore.


Who Should Get a Smart Sprinkler Controller?

If you have a sprinkler system that’s either manually operated or with an electronic timer, you should definitely consider switching to a smart sprinkler controller. This is a machine that takes advantage of modern advancements in connectivity. Using weather data gathered in real time, this smart controller will adequately determine just how much water needs to be applied to your property.

Of course, you have the option to not replace your current controller if you are okay with having to prepare the irrigation schedule using a small display screen and various confusing buttons.

In contrast, a smart sprinkler controller can be controlled with the use of a laptop or a smartphone. You could be anywhere in your house or even in another region and you can still view the settings as long as you have the app and an internet connection.

In doing so, you can save money. If the controller detects it will rain on that day, your sprinklers won’t be used to release an unnecessary amount of water. Saving water is a huge benefit for many people, especially considering that 40 states in the U.S. are expected to experiences water shortages in 10 years.

In fact, the Environmental Protection Agency (EPA) noted that smart controllers with a WaterSense label on them have the potential to save more than 8,000 gallons of water each year for each household. Ideally, 120 billion gallons of water and $435 million in costs will be saved annually if every family in the US switched to a smart sprinkler controller.

Upgrading from an electronic timer or a manual sprinkler system does not even mean it’s more complicated to use. A smart sprinkler controller is designed to have simple controls and software that anyone can understand in no time.

Furthermore, this machine can connect with other smart devices including cameras and smoke alarms. Thus, smart sprinkler controllers can help improve security features in your home.

An important thing to note, however, is that smart controls only work with sprinkler system placed underneath the ground with wired controllers. This machine cannot be used with hose timers or battery-operated controllers.


Factors to Consider

Before getting yourself a smart sprinkler controller, it would be wise to take note of three factors that will ultimately determine which model you will get: location, zone quantity, and the number of programs.

1. Location

A smart sprinkler controller can either be installed indoors or outdoors. An indoor model is not resistant to weather, and it is built to be plugged into a power outlet.

Specifically, an indoor sprinkler controller needs 110 outlet volts, which will then be converted to 18 volts by a transformer. If you want to install the controller in your garage, closet, shed, or on a shaded patio, you should get an indoor variant.

On the other hand, an outdoor sprinkler timer is both sturdy and weather-resistant. Instead of having to be plugged into an outlet, this type should be hard wired for power. In this type, the transformer is found within the weather-resistant casing.

What’s interesting is that since an outdoor model typically has more features than the indoor variants, people would still install it indoors using a three-pronged plug and power cord.

2. Zone Quantity

First of all, what is a zone? Well, this is the term we use to refer to the sections in your property that are determined by a sprinkler system upon installation. Once the area has been divided into these zones, a sprinkler timer will designate one station to handle one zone.

The average household is has a property with two to nine zones. On the other hand, commercial or public areas are divided into as many as 48 zones. Thus, it’s important to know how many zones a smart sprinkler controller can accommodate before you buy one.

A good tip is to buy a smart controller that can handle more zones than necessary since these extra stations will be handy when you expand your remodel your property.​

3. Number of Programs

If you want variety in how your lawn is watered, you should get a sprinkler controller that offers the largest amount of program designs. Some people will be okay with models that only have two program designs. However, you would need more than a couple of program designs if you want several stations operating using different schedules at the same time.


Features to Evaluate

Rain Sensor

Thanks to this type of sensor, a smart sprinkler controller can precisely determine if and when irrigation should be conducted depending on the precipitation it senses.

Self-Diagnostics

This is a safety feature that can involve an installed mechanism that prevents short circuits or a diagnostic program that analyzes fluctuations in water usage.

Memory

If your area is prone to power outages or occasional brownouts, it would be wise to get a smart sprinkler that contains a backup battery. If this is not included, an alternative to look for is a non-volatile memory that will remember the designated program even when it runs out power.

Scheduling Options

Last but not the least, smart sprinkler controllers differ in how detailed their scheduling options can be. Some models allow monthly scheduling while others let you schedule the irrigation on a weekly or even daily basis.​
