How to integrate a standalone, non-ESP32 NFC tag reader?

Configuration

I’m having a hard time conceptualizing how the Tags integration is supposed to work with standalone tag readers outside of the ESPHome ecosystem.

I’m building a device for my home based on a Raspberry Pi Zero 2 W, and would like to integrate a NFC reader if possible: scan a tag on the device to trigger automations within Home Assistant via the Tags integration.

If I were building off of an ESP32 board, I’d follow the excellent instructions for adonno’s tag reader. Without that, plugging a reader directly into my Home Assistant server, or using the mobile app, however, I’m uncertain how to get the data from the Pi to HA.

Is this possible? If so, how?

I asked this elsewhere and was pointed to the MQTT Tag integration, which appears to be what I was looking for.

I was also wondering how to use a Raspberry Pi. This is great; thanks!

How did you set it up?

This device still only exists as a concept within my mind. Maybe one day, I’ll get to building it.

I went ahead and bought some ESP32 ones. I was hoping to avoid wireless devices :confused:.

I know this is an old post but perhaps someone else will find this solution useful.

I accidentally purchased a USB Tag reader for my ESP32 build. While I’m waiting for the proper tags I built a tag reader script that will work with MQTT.

Its AI rubbish but it does seem to work, in MacOS and RPI4.
