Wemos D1 Mini - MX RM 5V, FS 1000, no Data

Dear Forum,

I have a Wemos D1 mini and would like to use an MHz receiver and an FS1000A transmitter.
Since both are 5V modules, I connect the 5V pin from the Wemos to the modules and use a voltage divider to reduce the data input to 3V for each.

I am following this tutorial as a guide:

Mein Schalplan:

Unfortunately, I do not get any output when I press buttons on my remote control nearby.

hat's why I created a simple sketch that sends and receives data.

#include <Arduino.h>
#include <RCSwitch.h>

// Sender und Empfänger-Objekte
RCSwitch mySwitch = RCSwitch();

void setup() {
  Serial.begin(9600);

  // Sender auf Pin D8 (GPIO 15)
  mySwitch.enableTransmit(15);

  // Empfänger auf Pin D2 (GPIO 4)
  mySwitch.enableReceive(4);

  Serial.println("Setup abgeschlossen. Sender und Empfänger bereit.");
}

void loop() {
  // Signal senden
  Serial.println("Sende Signal: 123456789");
  mySwitch.send(123456789, 24); // Signal mit 24 Bit senden
  delay(1000); // Warte eine Sekunde, um das Signal zu senden

  // Signal empfangen
  if (mySwitch.available()) {
    unsigned long receivedValue = mySwitch.getReceivedValue();

    if (receivedValue == 0) {
      Serial.println("Ungültiges Signal empfangen.");
    } else {
      Serial.print("Empfangenes Signal: ");
      Serial.println(receivedValue);
    }
    mySwitch.resetAvailable();
  } else {
    Serial.println("Kein Signal empfangen.");
  }

  delay(1000); // Warte eine Sekunde, bevor die nächste Schleife beginnt
}

thank you for your help
