A weather smart irrigation controller uses local weather data to adjust the watering times for your garden, ensuring it gets the water it needs without overwatering.

You may be able to convert a standard irrigation controller to a weather smart one by connecting a weather smart component to your existing controller.

By only watering as much as your garden needs, you can reduce watering by around 15% while keeping plants healthy.

How do weather smart irrigation products work?

They use local weather data to adjust watering times, based on temperature and rainfall, to ensure your garden gets the moisture it needs, without over-watering. Some of the controllers are Wi-Fi enabled, allowing them to obtain weather data via the internet others use onsite weather stations. Many controllers also allow remote access, which means you can control your irrigation system via your mobile or computer.

We recently ran a trial where 60 customer's irrigation controllers were upgraded to weather based models. It was found that even with less water gardens remained healthy. The average household reduced their garden watering by 15% (around 95,000 litres) in the first year.

The graph below highlights the water savings that can be made. The dark blue bars show the amount of water used each month with a weather based controller. It's clear that watering according to the weather will save a lot of water.

This graph highlights potential water savings. Dark blue bars show the water used with weather based controller and the significant reductions in cooler months.

Below you can see how much water can be saved each month by adjusting watering times based on the weather and with irrigation turned off from 1 July to 31 August during the Winter Sprinkler Switch-off.

This graph shows water savings achieved by adjusting watering times based on weather, with no irrigation from 1 July to 31 August during the winter sprinkler ban.

Of all the water that is used in a household, nearly half is used outdoors. Being smarter with how we water our gardens and turning irrigation off for the Winter Sprinkler Switch-off is a great way to make savings.
