A big thank you for your contribution. I modified the program according to your proposals. Everything is working. I am attaching you the pieces of code relating to the door contact.
My problem is solved.

  attachInterrupt(digitalPinToInterrupt(DOOR_PIN), DoorMoving, CHANGE);
  DoorChange = 1;
  LastDoor = 0;
}
void DoorMoving() {
    DoorChange = 1;
}

void readDoor() {
  if (DoorChange) {
    boolean Door = (digitalRead(DOOR_PIN));
    if (Door != LastDoor) {
      send(msgDoor.set((Door) == HIGH ? 1 : 0));
      LastDoor = Door;
      DoorChange = 0;
    }
  }
}

void loop() {
  unsigned long currentMillis = millis();
  readDoor();
  if (currentMillis - previousMillis >= UPDATE_INTERVAL) {
    previousMillis = currentMillis;
    readDHT();
    read1Wire();
  }
}

This is actually what I read while searching the docs. I will modify the sketches. In fact I have to modify 2 modules with DHT22 + 3 1-wire probes + 2 relays + 2 door contacts + pusher on an arduino nano RF. No problem and thanks again for your help.
