Azure Event Hub History Component Integration

S.C.O.R.E. → Resilience → Energy

Overview

The Azure Event Hub history component provides a reliable method to capture and store event data from various home capability systems. This capability enhances the resilience of energy management by ensuring that critical data is available for analysis and decision-making.

Benefits

• Improved visibility into energy usage patterns over time
• Enhanced system reliability by maintaining a history of events
• Facilitates better decision-making for energy conservation

Intent

This capability aims to integrate Azure Event Hub with home capability systems to record and retrieve historical event data. The outcome is a comprehensive log that supports energy resilience and operational efficiency.

Preconditions

• Home Assistant must be installed and configured.
• An active Azure account with Event Hub set up.
• Network connectivity to Azure services.
• Home Assistant installed and configured.
• Integration available and authenticated: UniFi.
• Device installed and reachable: Unifi Networks.

Actors

• Homeowner
• Family member
• Guest

Trigger

The capability is triggered by a new event being logged in the home capability system, such as changes in energy consumption or device state.

Workflow Description

1. Log New Event

When a new event occurs in the home capability system, it generates a log entry.

2. Check Azure Connectivity

The system checks if it can communicate with Azure Event Hub for data transmission.

3. Store Event Data

If connectivity is confirmed, the event data is sent to Azure Event Hub for storage.

4. Update History Log

The system updates the local history log to reflect the newly stored event.

5. Analyze Historical Data

Homeowners can access historical data to analyze energy usage patterns for informed decisions.

Postconditions

After the capability completes, the event data is securely stored in Azure, and the local history log is updated, allowing for future analysis.

Optional Enhancements

• Integrate with machine learning for predictive analytics
• Create visual dashboards for real-time energy monitoring
• Send notifications for significant energy usage changes
