Homebridge: Apple HomeKit Integration for Homelab

What I Built

Homebridge is a lightweight Node.js server that emulates the iOS HomeKit API, allowing you to integrate non-HomeKit devices with Apple’s HomeKit ecosystem. It acts as a bridge between your homelab’s smart devices and Apple’s Home app, enabling Siri voice control and HomeKit automation for devices that don’t natively support HomeKit.

Technical Stack
