Hi!
Thanks for help, now it works perfect :-)
Posting updated code:
/**
The MySensors Arduino library handles the wireless radio link and protocol
between your home built sensors/actuators and HA controller of choice.
The sensors forms a self healing radio network with optional repeaters. Each
repeater and gateway builds a routing tables in EEPROM which keeps track of the
network topology allowing messages to be routed to nodes.

REVISION HISTORY
Version 1.0 - idefix
DESCRIPTION
Arduino BH1750FVI Light sensor
communicate using I2C Protocol
this library enable 2 slave device addresses
Main address 0x23
secondary address 0x5C
connect the sensor as follows :
VCC >>> 5V
Gnd >>> Gnd
ADDR >>> NC or GND
SCL >>> A5
SDA >>> A4
