A DIY NFC tag reader project built on an ESP8266 D1 Mini and PN532 module, with ESPHome firmware designed specifically for Home Assistant. It includes firmware configuration, schematics, and 3D-printable case files for building the device.
Use cases
- read NFC tags to trigger Home Assistant automations
- build a DIY NFC tag scanner for smart home
- flash ESPHome firmware to a PN532 tag reader
- scan NFC tags for presence or scene control in Home Assistant
- build a tag reader with LED feedback and buzzer sounds
When to choose
- you use Home Assistant and want NFC tag-based automations
- you want a cheap, well-documented DIY hardware project with 3D-printable case
- you already use ESPHome and want an integrated tag reader
When to avoid
- you don't use Home Assistant or ESPHome
- you need a plug-and-play commercial NFC reader without soldering
- you need support for NFC platforms other than PN532
