Firmware for ESP32 boards that implements Apple HomeKit lock functionality with support for Apple Home Key, enabling NFC-based door unlocking via iPhone or Apple Watch. It works with common NFC reader modules (PN532, PN7160, ST25R3916) and integrates with Home Assistant via MQTT.
Use cases
- unlock a door by tapping an iPhone or Apple Watch with NFC
- build a DIY Apple Home Key smart lock without buying a proprietary lock
- add an ESP32-based HomeKit lock to Home Assistant
- flash prebuilt firmware onto an ESP32 with an NFC reader module
- integrate NFC door access with MQTT and home automation automations
- use Ethernet instead of Wi-Fi for a smart lock reader
When to choose
- you want Apple Home Key support on your own hardware without buying a compatible commercial smart lock
- you already own an ESP32 and a supported NFC module (PN532, PN7160, ST25R3916)
- you use Home Assistant or an MQTT-based smart home setup
- you want prebuilt firmware so no compilation is required
When to avoid
- you need encrypted flash storage for key material, which this project does not provide
- you want the newer Apple Aliro standard rather than HomeKit Home Key
- you need a turnkey commercial product rather than a DIY build requiring wiring and flashing
- your board is not an ESP32 variant supported by the firmware
