# Homebridge — Bring Any Smart Device to Apple HomeKit

> Homebridge is a lightweight Node.js server that bridges non-HomeKit smart home devices into Apple's Home ecosystem. It supports thousands of plugins covering cameras, lights, thermostats, and more.

## Install

Save in your project root:

# Homebridge — Bring Any Smart Device to Apple HomeKit

## Quick Use
```bash
sudo npm install -g homebridge homebridge-config-ui-x
sudo hb-service install --user homebridge
# Open http://localhost:8581 to configure
```

## Introduction
Homebridge exposes non-HomeKit devices to Apple's Home app by emulating the HomeKit Accessory Protocol. A single Raspberry Pi or always-on server can unify dozens of incompatible smart home brands under one roof.

## What Homebridge Does
- Runs a HAP (HomeKit Accessory Protocol) server that Apple devices discover on the local network
- Loads community plugins to support brands like Ring, Nest, TP-Link, Tuya, Hue, and thousands more
- Provides a web-based configuration UI (homebridge-config-ui-x) for plugin management and logs
- Supports child bridges so each plugin runs in its own process for stability
- Publishes accessories that appear natively in the iOS/macOS Home app and respond to Siri

## Architecture Overview
Homebridge is a Node.js process that loads plugins at startup. Each plugin registers accessories or platforms that map vendor APIs to HAP characteristics. The built-in mDNS advertiser makes accessories discoverable. Child bridge mode spawns separate HAP servers per plugin, isolating crashes and improving responsiveness.

## Self-Hosting & Configuration
- Runs on Linux, macOS, Windows, or Docker; Raspberry Pi is the most popular host
- Official Docker image available at `homebridge/homebridge`
- Config lives in `~/.homebridge/config.json`; the web UI can edit it visually
- Plugins install via npm or through the web UI's plugin search
- Systemd service or hb-service ensures Homebridge starts on boot

## Key Features
- Over 2,000 community plugins covering nearly every smart home protocol and brand
- Child bridge isolation prevents one faulty plugin from crashing the whole server
- Web dashboard with real-time logs, accessory status, and backup/restore
- Works entirely on the local network with no cloud dependency for HomeKit control
- Supports cameras with snapshot and live streaming via FFMPEG

## Comparison with Similar Tools
- **Home Assistant** — full home automation platform with dashboards and automations; Homebridge focuses solely on HomeKit bridging
- **Scrypted** — HomeKit and Google Home bridge with a focus on cameras; Homebridge has a broader plugin ecosystem
- **HOOBS** — commercial Homebridge distribution with a polished UI; Homebridge itself is free and community-driven
- **Matter** — emerging standard that may reduce the need for bridges, but legacy devices still require Homebridge
- **Node-RED with HomeKit nodes** — more flexible but requires manual flow programming

## FAQ
**Q: Does Homebridge require an Apple device to set up?**
A: You need an Apple device to pair Homebridge with HomeKit initially. After pairing, accessories work via any paired Apple device or HomePod hub.

**Q: Can Homebridge run alongside Home Assistant?**
A: Yes. Many users run both: Home Assistant for automations and dashboards, Homebridge for HomeKit integration of devices Home Assistant does not natively expose to HomeKit.

**Q: How many accessories can Homebridge handle?**
A: HomeKit supports up to 150 accessories per bridge. Child bridge mode lets you run multiple bridges to exceed this limit.

**Q: Is Homebridge affected by Apple's HomeKit architecture changes?**
A: Homebridge tracks HAP specification updates and adapts. The maintainers actively update the core library when Apple introduces changes.
