@hek right 
sizeof uint32_t : 4
it works with :
#define EEPROM_SLEEP_DURATION_ADDRESS 0
uint32_t sleepDurationInS = 86399;
hwWriteConfigBlock((void*)&sleepDurationInS, (void*)(EEPROM_LOCAL_CONFIG_ADDRESS+EEPROM_SLEEP_DURATION_ADDRESS), 4);
hwReadConfigBlock((void*)&sleepDurationInS, (void*)(EEPROM_LOCAL_CONFIG_ADDRESS+EEPROM_SLEEP_DURATION_ADDRESS), 4);
@tekka Hi, I found my mistake ! You were absolutely right when you said there is no sign of MYSBootloader in my GW log...
But now I know why :
I use an USBasp Programmer with Arduino IDE for upload my bootloader and my sketch..., and I mistakenly thought that when I upload bootloader then sketch, it keep bootloader.....but NOT, it overwrite bootloader 
I fix it by uploading the xxx.with_bootloader.hex file generated by Arduino IDE when compile.
Sorry for the inconvenience and thank you for your help
@esawyja Perhaps you should be inspired by this :

Hi,
in last MySensors lib version 2.1.0, I see a new sensor type : S_MOISTURE
It's more logicial to use this new type instead of S_HUM ?
and so use V_LEVEL instead of V_HUM ?
Thanks for respons
@tekka Hi Happy new year 2017 !!!
Many thanks for release source of MYSBootloader!!! A very good news !!!
Can you explain how to compile ?
Makefile in Master Branch failed with :
make: *** No rule to make target 'MYSBootloader.c', needed by 'MYSBootloader.o'.
I would like to compile an ATMega328 1Mhz version
Thanks
@MaKin
I have not done this build, but if I had to do it I will try with this
The most complicated is to find the Raid Power Sprayer
@mfalkvidd So where you buy the right led strip ?
Thanks for your reponse
Just for info, I found others methods to save data in eeprom :
in <avr/eeprom.h> there is :
uint8_t eeprom_read_byte (const uint8_t *__p)
uint16_t eeprom_read_word (const uint16_t *__p)
uint32_t eeprom_read_dword (const uint32_t *__p)
float eeprom_read_float (const float *__p)
void eeprom_read_block (void *__dst, const void *__src, size_t __n)
void eeprom_write_byte (uint8_t *__p, uint8_t __value)
void eeprom_write_word (uint16_t *__p, uint16_t __value)
void eeprom_write_dword (uint32_t *__p, uint32_t __value)
void eeprom_write_float (float *__p, float __value)
void eeprom_write_block (const void *__src, void *__dst, size_t __n)
void eeprom_update_byte (uint8_t *__p, uint8_t __value)
void eeprom_update_word (uint16_t *__p, uint16_t __value)
void eeprom_update_dword (uint32_t *__p, uint32_t __value)
void eeprom_update_float (float *__p, float __value)
void eeprom_update_block (const void *__src, void *__dst, size_t __n)
It is to these methods that the aliases are made in the file MyHwATMega328.h
#define hwReadConfig(__pos) eeprom_read_byte((uint8_t*)(__pos))
#define hwWriteConfig(__pos, __val) eeprom_update_byte((uint8_t*)(__pos), (__val))
#define hwReadConfigBlock(__buf, __pos, __length) eeprom_read_block((void*)(__buf), (void*)(__pos), (__length))
#define hwWriteConfigBlock(__buf, __pos, __length) eeprom_update_block((void*)(__buf), (void*)(__pos), (__length))
@hek right sizeof uint32_t : 4
it works with :
#define EEPROM_SLEEP_DURATION_ADDRESS 0
uint32_t sleepDurationInS = 86399;
hwWriteConfigBlock((void*)&sleepDurationInS, (void*)(EEPROM_LOCAL_CONFIG_ADDRESS+EEPROM_SLEEP_DURATION_ADDRESS), 4);
hwReadConfigBlock((void*)&sleepDurationInS, (void*)(EEPROM_LOCAL_CONFIG_ADDRESS+EEPROM_SLEEP_DURATION_ADDRESS), 4);
I try this :
#define EEPROM_SLEEP_DURATION_ADDRESS 0
uint32_t sleepDurationInS = 86399;
hwWriteConfigBlock((void*)sleepDurationInS, (void*)(EEPROM_LOCAL_CONFIG_ADDRESS+EEPROM_SLEEP_DURATION_ADDRESS), 32);
hwReadConfigBlock((void*)&sleepDurationInS, (void*)(EEPROM_LOCAL_CONFIG_ADDRESS+EEPROM_SLEEP_DURATION_ADDRESS), 32);
but seems no work my node freeze at this method
@mfalkvidd yes for this solution, I guess that hwWriteConfigBlock method access to the eeprom in one time, contrary to bit shifting technique that need 4 saveState so 4 access to the eeprom ?
