    I need to add two basic relays to the home assistant with Mysensors .but unfortunately I can add only one relay please help me

    // Enable debug prints to serial monitor
    #define MY_DEBUG
    
    // Enable and select radio type attached
    #define MY_RADIO_NRF24
    //#define MY_RADIO_NRF5_ESB
    //#define MY_RADIO_RFM69
    //#define MY_RADIO_RFM95
    
    // Enable repeater functionality for this node
    #define MY_REPEATER_FEATURE
    
    #include <MySensors.h>
    
    
    
    
    #define RELAY_PIN_1 4  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
    #define NUMBER_OF_RELAYS 2 // Total number of attached relays
    #define RELAY_ON 1 // GPIO value to write to turn on attached relay
    #define RELAY_OFF 0 // GPIO value to write to turn off attached relay
    
    
    void before()
    {
        for (int sensor=1, pin=RELAY_PIN_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
            // Then set relay pins in output mode
            pinMode(pin, OUTPUT);
            // Set relay to last known state (using eeprom storage)
            digitalWrite(pin, loadState(sensor)?RELAY_ON:RELAY_OFF);
        }
    }
    
    void setup()
    {
    
    }
    
    void presentation()
    {
        // Send the sketch version information to the gateway and Controller
        sendSketchInfo("Relay", "1.0");
    
    
        for (int sensor=1, pin=RELAY_PIN_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
            // Register all sensors to gw (they will be created as child devices)
            present(sensor, S_BINARY);
    
        }
    }
    
    
    void loop()
    {
    
    }
    
    void receive(const MyMessage &message)
    {
        // We only expect one type of message from controller. But we better check anyway.
        if (message.getType()==V_STATUS) {
            // Change relay state
            digitalWrite(message.getSensor()-1+RELAY_PIN_1, message.getBool()?RELAY_ON:RELAY_OFF);
            // Store state in eeprom
            saveState(message.getSensor(), message.getBool());
            // Write some debug info
            Serial.print("Incoming change for sensor:");
            Serial.print(message.getSensor());
            Serial.print(", New status: ");
            Serial.println(message.getBool());
        }
    }

      Hello
      It could be a case of presentation being done too fast. Add a wait(50) like this

       // Present all relays to controller
        for (int sensor=CHILD_ID_RELAY, pin=RELAY_1; sensor<CHILD_ID_RELAY+NUMBER_OF_RELAYS;sensor++, pin++) {
          // Register all sensors to gw (they will be created as child devices)
          present(sensor, S_LIGHT);
           wait( 50 ); // <--- byTheo

        I believe you have to send a state also, to have it show up in home assistant.
