Enhanced Prometheus Integration for Water Heater Metrics

S.C.O.R.E. → Resilience → Energy

Overview

The expanded Prometheus integration allows homeowners to monitor the performance and energy usage of their water heaters in real-time. This capability helps in optimizing energy consumption and identifying potential issues before they escalate.

Benefits

• Gain insights into energy consumption patterns of the water heater.
• Proactively monitor for any irregularities or performance issues.
• Enhance overall home energy management strategies.

Intent

This capability aims to provide detailed energy metrics for water heaters, enabling homeowners to make informed decisions about their energy use. The outcome is improved efficiency and reduced energy costs.

Preconditions

• Home Assistant must be installed and running.
• Prometheus integration must be configured in Home Assistant.
• Water heater must be compatible with Home Assistant and Prometheus.
• Home Assistant installed and configured.
• Integration available and authenticated: Zigbee2MQTT.
• Device installed and reachable: RainMachine Version 2 (API 4.6.1).

Actors

• Homeowner monitoring energy usage
• Family member alerted to performance issues
• Guest inquiring about water heating efficiency

Trigger

The capability is triggered by scheduled data exports from the Prometheus integration, typically set to occur at regular intervals.

Workflow Description

1. Initialize Prometheus Export

The Prometheus integration is set to begin exporting metrics from the water heater.

2. Collect Water Heater Data

Metrics such as temperature, energy consumption, and operational status are gathered.

3. Evaluate Data Availability

Check if the collected data is complete and ready for export.

4. Export Metrics to Prometheus

Send the collected metrics to Prometheus for storage and analysis.

5. Update Home Assistant Dashboard

Refresh the Home Assistant interface to display the latest water heater metrics.

Postconditions

The Home Assistant dashboard now reflects the latest metrics for the water heater, allowing for real-time monitoring and analysis.

Optional Enhancements

• Integrate alerts for when energy consumption exceeds a set threshold.
• Add historical data trends for better long-term analysis.
• Implement machine learning algorithms for predictive maintenance.
