Monitor Energy Production from Sun WEG Inverter

S.C.O.R.E. → Resilience → Energy

Overview

The Sun WEG capability allows homeowners to collect and monitor real-time energy production data from their Sun WEG inverter. This helps in optimizing energy usage and enhances overall energy management at home.

Benefits

• Track energy generation to maximize self-consumption of solar energy.
• Receive alerts for underperformance or anomalies in energy production.
• Gain insights into energy trends for better financial planning and sustainability.

Intent

This capability is designed to provide homeowners with a comprehensive overview of their solar energy production. By monitoring this data, users can make informed decisions about energy consumption and improve their home’s energy efficiency.

Preconditions

• Sun WEG inverter installed and operational.
• Home Assistant set up with the appropriate integration.
• Internet connection for data transmission.
• Home Assistant installed and configured.
• Integration available and authenticated: Zigbee2MQTT.
• Device installed and reachable: Energy Monitoring.

Actors

• Homeowner monitoring energy production
• Family members reviewing energy savings
• Energy consultant analyzing performance data

Trigger

The capability is triggered by a scheduled check of the inverter’s energy production data at set intervals.

Workflow Description

1. Initiate Data Retrieval

The system triggers a scheduled request to the Sun WEG inverter for the latest energy production data.

2. Check Data Availability

The system checks if the data from the inverter is available and valid.

3. Log Energy Production

If data is available, it is logged into the Home Assistant system for further analysis.

4. Update Dashboard

The logged energy data is updated in the Home Assistant dashboard for easy access and visualization.

5. Send Alerts

If data retrieval fails, an alert is sent to the homeowner to check the inverter or connection.

Postconditions

The energy production data is successfully logged and visible on the Home Assistant dashboard, allowing for ongoing monitoring and analysis.

Optional Enhancements

• Integrate weather data for predictive energy generation analytics.
• Set up automated actions based on energy production thresholds.
• Create visual reports for energy production trends over time.
