I write a program on library Stepper not AccelStepper.
Now is working.

Program code:

// Enable debug prints to serial monitor
#define MY_DEBUG 

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

// Enable repeater functionality for this node
#define MY_REPEATER_FEATURE

#include <SPI.h>
#include <MySensors.h>
#include <Stepper.h>

#define CURTAIN_CLOSED 1000  // wartosc gdy kurtyna zamknieta
#define CURTAIN_OPEN -1000         // wartosc gdy kurtyna otwarta 
#define CHILD_ID 1

// definicje MySensors 

MyMessage message(CHILD_ID, S_COVER);

int in1Pin = 3;
int in2Pin = 4;
int in3Pin = 5;
int in4Pin = 6;
int lastState;
 
// liczba kroków na jeden obrót
#define stepsPerRevolution 200

//ustawienie szybkości silnika 
int motorSpeed = 40;

Stepper myStepper(stepsPerRevolution, in1Pin, in2Pin, in3Pin, in4Pin);

void setup() {
  
// ustawienie pinów jako wyjście
  pinMode(in1Pin, OUTPUT);
  pinMode(in2Pin, OUTPUT);
  pinMode(in3Pin, OUTPUT);
  pinMode(in4Pin, OUTPUT);
// ustawienie szybkosci silnika
  myStepper.setSpeed(motorSpeed);
}

void presentation()  
{ 
  // Wyslanie informacji o wersji programu
  sendSketchInfo("Program kurtyna", "1.0");
  // Register all sensors to gw (they will be created as child devices)
  present(CHILD_ID, S_COVER); // Window Cover sub-type, commands: V_UP, V_DOWN, V_STOP
}

void receive(const MyMessage &message) {
  // if message = V_UP start moving until closed
  if (message.type==V_UP) {
     myStepper.step(CURTAIN_OPEN);
     // Store state in eeprom
     saveState(message.sensor, message.getBool());
     request(CHILD_ID, V_UP, 0); // request new values from controller
        }
     
 if (message.type==V_DOWN) {
     myStepper.step(CURTAIN_CLOSED);
     // Store state in eeprom
     saveState(message.sensor, message.getBool());
     request(CHILD_ID, V_DOWN, 0); // request new values from controller
        } 
}

I use MySensors Library 2.0

Hello.

To my project i use stepper motor JK42HS34-0404 and driver L298N.

This is a wiring diagram.

This is a program code that I use

#include <MySensor.h>  
#include <SPI.h>
#include <AccelStepper.h>
#define HALFSTEP 4  // Stepper uses "Halfstep" mode
#define CURTAIN_CLOSED 1000 // value when closed
#define CURTAIN_OPEN 0 // value when open
#define CHILD_ID 1   // Id of the sensor child
// MySensors definitions
MySensor gw;
// Initialize message
MyMessage msg(CHILD_ID, V_TRIPPED);


// Motor pin definitions
#define motorPin1  3     // IN1 on the ULN2003 driver 1
#define motorPin2  4     // IN2 on the ULN2003 driver 1
#define motorPin3  5     // IN3 on the ULN2003 driver 1
#define motorPin4  6     // IN4 on the ULN2003 driver 1

// Initialize with pin sequence IN1-IN3-IN2-IN4 for using the AccelStepper with 28BYJ-48
AccelStepper stepper1(HALFSTEP, motorPin1, motorPin2, motorPin3, motorPin4);

unsigned long current_position ; // remembers current position, need to be saved in EEPROM?

void setup() {
  // MySensors
  gw.begin(); // fixed node 13
  gw.sendSketchInfo("Curtain control 13", "1.0"); // Send the sketch version information to the gateway and Controller

  //pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as input
  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID, S_COVER); // Window Cover sub-type, commands: V_UP, V_DOWN, V_STOP
  
  stepper1.setMaxSpeed(500.0);
  stepper1.setAcceleration(700.0);
  stepper1.moveTo(CURTAIN_OPEN);
  
  current_position = CURTAIN_OPEN ;
  stepper1.moveTo(CURTAIN_OPEN);
}//--(end setup )---

void loop() {
  // if message = V_UP start moving until closed
  // if message = V_DOWN start moving back until open
  // if message = V_STOP stop moving
  // Test: Change direction when the stepper reaches the target position
  gw.process(); // check if message from controller
  if (stepper1.distanceToGo() == 0){
    if (stepper1.currentPosition() == CURTAIN_OPEN){
      stepper1.moveTo(CURTAIN_CLOSED);
      Serial.println("Curtain Open, now closing");
      gw.request(CHILD_ID, V_UP, 0); // request new values from controller  
    }
    else{
      stepper1.moveTo(CURTAIN_OPEN);
      Serial.println("Curtain Closed, now opening");
      gw.request(CHILD_ID, V_DOWN, 0); // request new values from controller   
    }
  }
  
  stepper1.run();
}

// This is called when a message is received 
void incomingMessage(const MyMessage &message) {
  // We only expect few types of messages from controller, check which
  stepper1.moveTo(message.getInt() * CURTAIN_CLOSED/100);
  Serial.print("Message - valid: ");
  Serial.print(message.sensor);
  Serial.print(" , value: % ");
  Serial.println(message.getInt());
  switch (message.getInt()) {
  case 100:
    // Curtain should be opened
     Serial.print("Message - valid: ");
     Serial.print(message.sensor);
     Serial.print(", Message UP ");
     stepper1.moveTo(CURTAIN_OPEN);
     break;
  case 0:
    // Curtain should be closed
     Serial.print("Message - valid: ");
     Serial.print(message.sensor);
     Serial.print(", Message DOWN ");
     stepper1.moveTo(CURTAIN_CLOSED);
    break;
  case 50:
    // Curtain action should be stopped
     Serial.print("Message - valid: ");
     Serial.print(message.sensor);
     Serial.print(", Message STOP ");
    break;
  default: 
    // not recognizable message
     Serial.print("Message - valid: ");
     Serial.print(message.sensor);
     Serial.print(", Unrecognized ");

  }
 
}

When the program I have uploaded to my mysensors, the engine still turns, one left and one to the right and did not work the button blinds in Domoticz.

I cant turn off my stepper motor in Domoticz.

Please help me.

Now the wiring diagram should be visible.
