FIXED!
Happy

Issue was so obvious...
I was supplying Neopixel LED's with 5V trought Arduino pro mini... so when node was starting everything was ok till sending light pattern to node. When data was send, LED's took to much Watts, and radio was crashing...
So now I just powered LED's with 5V parerall to the node ( LED's are supplied before node).

Now, I need to understand your code, how "buttonPin" is working and how to set patterns. It seems that the code is acting wired sometimes, but I think that's due to my less knowledge about it now.

Thanks for guidlines!

topic to close.
I've neede to allow new hardware to add in Domoticz.

OK,
I was tired...
I've figure it out and have sketch running
Beta version:

// Enable debug prints
#define MY_DEBUG

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

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

#define CHILD_ID_DUST 0
#define MIN_VOLTAGE              600 // mv - the lower threshold voltage range for the lack of dust
#define VREF                    1100 // mv - reference voltage of the comparator
#define DUST_SENSOR_DIGITAL_PIN    3 // pin number ILED
#define DUST_SENSOR_ANALOG_PIN     1 // pin number AOUT
#define MAX_ITERS                 10 // liczba pomiarow do sredniej


unsigned long SLEEP_TIME = 1000;    // Sleep time between reads (in milliseconds)

int SAMPLING_TIME = 280;
int ADC_VALUE; // read value A1
int ITER; // value read
float VOLTAGE; // voltage value
float DUST; // result
float AVG_DUST; // average result

MyMessage dustMsg(CHILD_ID_DUST, V_LEVEL);

void setup(){
  analogReference(INTERNAL);
  Serial.begin(115200);
  pinMode(DUST_SENSOR_DIGITAL_PIN,OUTPUT);
  digitalWrite(DUST_SENSOR_DIGITAL_PIN, LOW);
}

void presentation() {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("Dust Sensor", "1.0");

  // Register all sensors to gateway (they will be created as child devices)
  present(CHILD_ID_DUST, S_DUST);  
}

float computeDust()
{
  // Flash IR, wait 280ms, read ADC voltage
  digitalWrite(DUST_SENSOR_DIGITAL_PIN, HIGH);
  delayMicroseconds(SAMPLING_TIME);
  ADC_VALUE = analogRead(DUST_SENSOR_ANALOG_PIN);
  digitalWrite(DUST_SENSOR_DIGITAL_PIN, LOW);
 
  // Calculate to mV. whole multiplied by 11, because in the module
  // applied voltage divider 1k/10k
  VOLTAGE = (VREF / 1024.0) * ADC_VALUE * 11;
 
  // Calculate pollution if the measured voltage over prog
 
  if (VOLTAGE > MIN_VOLTAGE)
  {
    return (VOLTAGE - MIN_VOLTAGE) * 0.2;
  }
 
  return 0;
}
 
void loop()
{
   AVG_DUST = 0;
   ITER = 0;
 
   while (ITER < MAX_ITERS)
   {
     DUST = computeDust();
     // For medium liczmy only correct measurements
     if (DUST > 0)
     {
       AVG_DUST += DUST;
       ITER++;
       delay(50);
     }     
   }
   
  AVG_DUST /= MAX_ITERS;
   
   Serial.print("D = ");
   Serial.print(AVG_DUST);
   Serial.println("ug/m3");    

  send(dustMsg.set((int)ceil(AVG_DUST)));
  
  sleep(SLEEP_TIME);

}

Values are send, but I want to send to gateway values exact as computed by sketch, wih 4 ditits - D = 60.79ug/m3

But sketch is sending only 2 digit - ok:61

D = 60.79ug/m3
TSP:MSG:SEND 8-8-0-0 s=0,c=1,t=37,pt=2,l=2,sg=0,ft=0,st=ok:61
D = 59.61ug/m3
TSP:MSG:SEND 8-8-0-0 s=0,c=1,t=37,pt=2,l=2,sg=0,ft=0,st=ok:60

I guess that I should change something here:

  send(dustMsg.set((int)ceil(AVG_DUST)));

But not know what to change.
Help here.
