Rachio 3 sprinkler controller

Rachio 3 smart sprinkler controller

Most lawns are overwatered. Hosepipes and sprinklers can easily use up to 1,000 litres of water an hour. The Rachio 3 smart sprinkler controller is designed to monitor your water usage by creating customised watering schedules, preventing damaging over-watering of plants and reducing water consumption.

What is the Rachio 3 and how do I use it?

The Rachio 3 controller creates an adjustable watering schedule for use with your existing irrigation sprinkler system. The accompanying mobile app lets you manage your system from anywhere. The Rachio 3 controller can be installed without any digging or plumbing , taking less than 30 minutes to hook up to your pipes without any technical expertise necessary.

Once the Rachio 3 is installed, you’ll need to connect the controller to your home wifi, and then download the mobile app (available for Android and iOS) onto your phone to set the system up.

The Rachio 3 is also compatible with smart speakers including Alexa and Google Assistant so you can start your sprinkler by shouting commands across your living room.


Customised zones

The Zones feature allows you to set up parameters for each area in your garden, and you can add details such as soil type, sprinkler type, sun exposure and slope to optimise the watering schedule for that patch.

Personalised schedules

You can easily set up watering schedules to work around your lifestyle. The Flex Daily schedule is based on local weather conditions, which is the best setting for potential water savings. The Flex Monthly updates every month to adapt for seasonal changes. The Fixed schedule allows for custom watering schedules based on time, duration and days of the week. There is also the option of Weather Intelligence settings such as Wind and Freeze, which delays the watering when it’s too windy or frosty, ensuring delicate perennials make it through the winter months.

Hyperlocal weather monitoring

The device is fitted with Premium Weather Intelligence Plus technology, which gathers weather data from over 300,000 weather stations, satellites and radar sources to present the most accurate watering schedule for your area.

Advanced smartphone control

The great part about this device is that you can control the watering from anywhere you like, as long as you have an internet connection.


The Rachio 3 is currently priced at $229 USD (£177) available from Racio’s website or other US based retailers.
