Hi, im trying to create this NFC "vhs player" from thestockpot https://www.thestockpot.net/videos/cartrdgeplayer, Im using an esp32 c6 with an RC522 reader, im unable to view any entities or read the tags in home assistant but they seem to show up on the web . esphome logs properly
any idea what i could be doing wrong here?

#

heres the code (ps:im very new to this and used chat gpt to modify the original code)

this might be better asked on the ESPHome discord server.
but some thoughts after giving things a look over.
you should update your home assistant install
then your esphome builder tool which i assume may also be out of date.

the example code for the project uses the arduino framework instead of esp-idf which you have here. although I don't know if there's any difference with these components.

using an LLM to modify stuff might not always work out well. its worth looking through the esphome documentation and seeing if the stuff is correct or not where it made changes.
