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());
    }
}
