hey @dewy721 currently you cannot use unused I/O pins unfortunately. You would like to drive a specific pin with a MQTT call directly? Bypassing all the esp-rfid functionality? esp-rfid already manages a led and buzzer for feedback, so I'm not sure what you have in mind in detail? |

Well, I was imaging connections for i2c lcd output (for MQTT based
messages).

MQTT direct I/O? Sounds useful as well.

OK, that sounds interesting :) Currently there's nothing to drive this though. If you want to work on this feel free to ask, I can help you to get started! |

Is there a way to use MQTT to control the unused I/O pins?
The readers we use have an RGB status led, and a piezo buzzer for user feedback. Breakouts with one wire for each.
