Smart Meter AsyncAPI

An AsyncAPI specification for real-time smart meter telemetry data consumption.

Overview

This repository contains an AsyncAPI 2.6.0 specification that defines an event-driven API for consuming smart meter reading data. The API enables real-time monitoring and processing of utility meter readings through asynchronous messaging.

API Specification

The API defines a single channel for smart meter data:

• Channel: smartmeter/reading
• Operation: Subscribe to meter readings
• Content Type: application/json

Message Format

Each smart meter reading message contains:

{
  "meterId": "string",
  "timestamp": "2024-01-01T12:00:00Z",
  "reading": 1234.56
}

Usage

1. View the specification: Open smartmeterasynchapi.yaml in an AsyncAPI viewer or editor
2. Generate code: Use AsyncAPI tools to generate client/server code
3. Integration: Implement the subscription pattern to receive meter readings

AsyncAPI Tools

• AsyncAPI Studio - Online editor and viewer
• AsyncAPI Generator - Code generation tool
• AsyncAPI CLI - Command-line interface

Example Implementation

// Example Node.js subscriber using AsyncAPI generated code
const subscriber = new SmartMeterSubscriber();

subscriber.receiveSmartMeterReading((message) => {
  const { meterId, timestamp, reading } = message.payload;
  console.log(`Meter ${meterId}: ${reading} at ${timestamp}`);
  
  // Process meter reading data
  processReading(meterId, reading, timestamp);
});

Use Cases

• Real-time monitoring: Track energy consumption patterns
• Billing systems: Automated meter reading for utility billing
• Grid management: Monitor electrical grid load and distribution
• Analytics: Collect data for energy usage analysis
• Alerting: Detect anomalies or threshold breaches
