HomeLink - Distributed Home Network Monitoring

A sophisticated distributed Go service for home network monitoring with automatic leader election and service discovery.

Project Overview

HomeLink is a distributed service designed to run on multiple devices across a home network, including Raspberry Pi, ARM64-based Macs, and Windows machines. The system features automatic service discovery, secure leadership election, and unified API access for comprehensive home network monitoring.

Key Features

  • 🔍 Automatic Service Discovery - Seamless detection and connection of services across private networks
  • ⚖️ Leadership Election - Secure leader election with shared secret authentication and automatic failover
  • 🏠 Multi-Platform Support - Native support for Raspberry Pi, ARM64 Macs, Windows, and Linux systems
  • 📡 UPnP Integration - Automatic port forwarding configuration for external network access
  • 🎯 Centralized Monitoring - Real-time monitoring of configured IP/port combinations across the network
  • 🔌 API Request Forwarding - Intelligent routing of API requests to the elected leader
  • 🏢 Coordinator Mode - Optional centralized management mode for multi-network deployments
  • 📚 Swagger Documentation - Interactive API documentation and testing interface

Architecture

HomeLink follows a distributed architecture pattern with the following components:

  • Service Discovery: Automatic detection of HomeLink instances on the network
  • Leader Election: Democratic selection of a primary coordinator with priority-based voting
  • Monitoring Engine: Continuous health checks of configured services and endpoints
  • API Gateway: RESTful interface with automatic request forwarding to the leader
  • UPnP Manager: Dynamic port forwarding management for external accessibility
