Save GPIO state on flash/eeprom

#1 Post by hsic » 15 Sep 2019, 23:16

Hello!
I use EspEasy mega-20180130, i would save the gpio state, ex. every minute, in an .txt file, when esp boot (if occur a power outage or reboot) must read this .txt file and set the GPIO variable according to the last save.

How i can do that?
thanks

Currently no but it's planned to have external EEPROM support.

What is the intended use case?
For me .... to let relay's controlling pumps survive their activity despite all watchdog reboots

I store GPIO states controlling a relay, in a dummy task.
With a Rule:
"On System#Boot do"
I restore the last known GPIO state

This works for a hot-boot, NOT a power outage.
30+ ESP units for production and test. Ranging from control of heating equipment, flow sensing, floor temp sensing, energy calculation, floor thermostat, water usage, to an interactive "fun box" for my grandson. Mainly Wemos D1.

For now i've solved with an UPS to avoid any power outage...
hope that this features (persistant relay mode in case of power outage) will be arrive soon as possible.

Thanks
