What usecase do you have in mind? 🤔 In other words, a single reader can be used to control as many locks as you want. Using two or more readers with the esp32 is definitely possible over SPI, although that’s not implemented yet in this project’s code. |

As far as I know the esp32-pn532 combo is independent of the lock and the unlock logic is done using an automation service like Home Assistant or NodeRed based on the mqtt messages that the ESP32 broadcasts.
