    listen i have a problem, because i want to create such a sensor that if the door is opened and the card is not bounced, something will happen there in home asistant, but what i mean is, how to connect it? and the signal will be sent over the internet via internet cable and i want to create it with w5500, rc522 and 3 reed switches and all this i want to connect under esp32 and have it work in esphome (HA).
    AI: How do you plan to connect the W5500, RC522 and reed switches to the ESP32? Do you already have a wiring diagram?
    W5500 → ESP32
    SCK → GPIO18
    MISO → GPIO19
    MOSI → GPIO23
    CS → GPIO15
    RST → GPIO2
    VCC → 5V
    GND → GND


    RC522 → ESP32
    SCK → GPIO18
    MISO → GPIO19
    MOSI → GPIO23
    CS (SDA) → GPIO5
    RST → GPIO4
    VCC → 3.3V
    GND → GND

    AI: Do you already have any settings configured in ESPHome for these devices? If so, which ones?
    not something I tried, but the same errors kept popping up

    What errors were popping up? It looks like you will need to use a binary sensor:
