combine working 4 relay with buttons with HC-SR501 motion sensor

[Dick]

I still have difficulty with combining sensors but learn a lot, Now I try to combine my working 4 relay sensor with 4 buttons with a HC-SR501 motion sensor . I want to use the pir information in my Domoticz controler. If the pir information is available in Domoticz , I can decide what to do.
Any help is Welcome.
Here my working 4 relay and 4 button code

#include <MySensor.h>
#include <SPI.h>
#include "Bounce2.h"

#define RELAY_ON 0                      // switch around for realy HIGH/LOW state
#define RELAY_OFF 1

//
MySensor gw;

#define RADIO_ID 11                    // radio Id, whatever channel you assigned to
#define noRelays 4
const int relayPin[] = {A1, A2, A3, A0}; //  switch around pins to your desire
const int buttonPin[] = {A5, 6, 7, 8}; //  switch around pins to your desire

class Relay             // relay class, store all relevant data (equivalent to struct)
{
public: 
  int buttonPin;                    // physical pin number of button
  int relayPin;                     // physical pin number of relay
  byte oldValue;                    // last Values for key (debounce)
  boolean relayState;               // relay status (also stored in EEPROM)
};

Relay Relays[noRelays];
Bounce debouncer[noRelays];
MyMessage msg[noRelays];

void setup()
{
  gw.begin(incomingMessage, RADIO_ID, true);
  delay(250);
  gw.sendSketchInfo("Multy-Relay&Pulsanti", "0.2");
  delay(250);

  // Initialize Relays with corresponding buttons
  for (int i = 0; i < noRelays; i++)
  {
    Relays[i].buttonPin = buttonPin[i];              // assign physical pins
    Relays[i].relayPin = relayPin[i];
    msg[i].sensor = i;                                   // initialize messages
    msg[i].type = V_LIGHT;
    debouncer[i] = Bounce();                        // initialize debouncer
    debouncer[i].attach(buttonPin[i]);
    debouncer[i].interval(5);
    pinMode(Relays[i].buttonPin, INPUT_PULLUP);
    pinMode(Relays[i].relayPin, OUTPUT);
    Relays[i].relayState = gw.loadState(i);                               // retrieve last values from EEPROM
    digitalWrite(Relays[i].relayPin, Relays[i].relayState ? RELAY_ON : RELAY_OFF); // and set relays accordingly
    gw.send(msg[i].set(Relays[i].relayState ? true : false));                 // make controller aware of last status
    gw.present(i, S_LIGHT);                               // present sensor to gateway
    delay(250);

  }
}

void loop()
{
  gw.process();
  for (byte i = 0; i < noRelays; i++)
  {
    debouncer[i].update();
    byte value = debouncer[i].read();
    if (value != Relays[i].oldValue && value == 0)
    {
      Relays[i].relayState = !Relays[i].relayState;
      digitalWrite(Relays[i].relayPin, Relays[i].relayState ? RELAY_ON : RELAY_OFF);
      gw.send(msg[i].set(Relays[i].relayState ? true : false));
      gw.saveState( i, Relays[i].relayState );
    }                 // save sensor state in EEPROM (location == sensor number)

    Relays[i].oldValue = value;

  }
}

// process incoming message
void incomingMessage(const MyMessage &message)
{

  if (message.type == V_LIGHT)
  {
    if (message.sensor < noRelays)            // check if message is valid for relays..... previous line  [[[ if (message.sensor <=noRelays){ ]]]
    {
      Relays[message.sensor].relayState = message.getBool();
      digitalWrite(Relays[message.sensor].relayPin, Relays[message.sensor].relayState ? RELAY_ON : RELAY_OFF); // and set relays accordingly
      gw.saveState( message.sensor, Relays[message.sensor].relayState ); // save sensor state in EEPROM (location == sensor number)
    }
  }
