## What it is
HomeSpan is an Arduino library for building custom Apple HomeKit accessories on ESP32 microcontrollers, implementing the HAP-R2 protocol directly without external bridges. It lets developers control devices via the Apple Home app or Siri over WiFi.

## Use cases
- build a custom HomeKit light switch with ESP32
- control DIY hardware from Siri
- create HomeKit temperature sensor on ESP32
- implement HAP-R2 accessory in Arduino IDE
- add OTA-updatable HomeKit device to Apple Home

## When to choose
- you want native HomeKit accessories without a bridge
- you develop in the Arduino IDE on ESP32-family chips
- you need full HAP-R2 compliance with OTA support

## When to avoid
- you use ESP8266 or non-ESP32 hardware
- you don't have a HomeKit hub (HomePod or Apple TV)
- you need HomeKit support outside the Arduino ecosystem

## Facets
- artifact type: library
- maturity: active
- function: sdk, embedded, security, networking
- domain: iot, embedded-systems
- platform: cpp, embedded, iot
- tags: homekit, esp32, arduino, hap-r2, siri, apple-home, smart-home-devices, automation
