S.C.O.R.E. → Resilience → Energy

Overview

The newly added flow and rain sensor support in the Hydrawise integration helps homeowners manage their irrigation systems more efficiently. By utilizing real-time data, it prevents over-watering and conserves water, ultimately leading to reduced utility bills and a healthier garden.

Benefits

• Prevents water wastage by monitoring flow and rain conditions.
• Enhances plant health by ensuring optimal watering levels.
• Saves money on water bills through efficient irrigation management.

Intent

This capability aims to provide real-time monitoring and management of home irrigation systems through the Hydrawise integration. The outcome is a more efficient watering schedule that adapts to environmental conditions, ensuring plants receive the right amount of water.

Preconditions

• Hydrawise integration must be installed in Home Assistant.
• Flow and rain sensors must be properly configured and connected.
• Home Assistant installed and configured.
• Integration available and authenticated: Zigbee2MQTT.
• Device installed and reachable: RainMachine Version 2 (API 4.6.1).

Actors

Workflow Description

1. Read Sensor Data

The system reads the current status of the flow and rain sensors.

2. Evaluate Rain Condition

The system checks if rain has been detected and adjusts watering schedules accordingly.

3. Monitor Water Flow

The system monitors the flow rate to ensure it remains within acceptable limits.

4. Adjust Irrigation Schedule

Based on sensor readings, the irrigation schedule is adjusted to optimize water usage.

5. Notify Homeowner

If there are issues with water flow, the homeowner receives an alert to take action.

Postconditions

After the capability completes, the irrigation system operates based on real-time environmental data, ensuring efficient water use and optimal plant health.

Optional Enhancements

• Integrate with weather forecasting services for proactive irrigation management.
• Implement notifications for significant changes in water usage patterns.
• Add graphical data representation for monitoring historical sensor performance.
