Smart Garden Watering System

Use Casesvg>

Brief: I want to have a smart garden watering system that monitors of the flowerbeds.

If the lawn suffers from a lack of water in the summer, this is reflected in unattractive brown spots, weeds and lack of growth. To save you from this, in this Use Case we’ll show you how you can implement a smart garden watering system with Loxone.

Solution: How to use Loxone to automate a smart garden watering system.

In our example, the garden is watered using water stored in a rainwater tank. The tank is equipped with an Ultrasonic Sensor that checks the water level. If the water level is too low, the garden is watered with normal water. The water level can also be checked at any time from the Loxone App.

Automatic watering can be activated in several ways. Either by using the weather forecast via the Weather Station or the Weather Service or by using moisture sensors in the garden. Two hours before sunrise watering will take place under the following conditions:

  • If there is enough water in the tank (as measured by the Ultrasonic Sensor)
  • If it is not currently raining (as determined by the Weather Station / Weather Service)
  • If the soil is not moist enough (as measured by the soil moisture sensor)
  • If a pre-defined amount of rain is not expected within the next 4 hours
  • If the temperature is not expected to fall below 4°C – to prevent frost

If these conditions are all met then water will take place and automatically stop at sunrise. The smart garden watering system can also be manually activated via the Loxone App.

All four valves are connected to a Radio Buttons Function Block. The four valves water the garden in 60-second intervals.

Additionally, if there’s a risk of frost, the water in the pipes is blown out with air for 5 minutes to prevent them from freezing.
