Loosing all data from setup and automation

[Krky1]

Hi, I have a problem with storing setting in my controller.
I am using Wemos d1mini V3, i try with Wemos d1mini pro, and have same issue.
Every time I turn off the power all settings are lost (Temperature sensor addresses, PID tuning setup and everything).
also when I update automation process over network when press set everything is lost.
it seems there is some problem with writing and storing data in EEPROM.
any help?

1. try another d1mini. There are so cheap that quality control seems to be an issue.
2. try formatting the file system. You can find how to do it in the document.
3. Try disconnecting d1mini from the board. Connect it direct to your PC, and try saving the settings and etc.

Problem solved,
SPI/FSS was not defined correctly.
In platformio.ini file line 152 changed from:
build_flags = -Wl,-Tesp8266.flash.4m.ld -DMultipleSensorEnabled=true
to
build_flags = -Wl,-Tesp8266.flash.4m2m.ld -DMultipleSensorEnabled=true
