OpenSprinkler (OS) lifetime internal memory

[zoic21]

Hello,

I just buy an OpenSprinkler (OS) but I have a question about lifetime of EEPROM. I see we can enable or not log of action on zone what is the impact on lifetime ? I known 8266 have a lifetime about 10K write how OpenSprinkler handle that ?

Thanks in advance for your return

ESP8266 uses an external NOR flash, it’s not a EEPROM. The write cycle is about 100K (not 10K). Also, the write cycle limit is for each sector, not the entire flash at once. That means, if you repeatedly write into the same sector 100K times, then that sector may approach the end of its life. Log files are written into different sectors each day. The firmware will erase old files when it runs out of flash memory space, which means it will take a long time (months, years) to come to the same sector again.

Ok so no subject on that lifetime is far more than 10 years.

Thanks you for your reply
