Flash_write_interval

ESPHome
1

Good morning everyone,
sorry my bad english.
is it possible to force the write in the memory flash?
I have placed the flash_write_interval on a very long period and I would like to record my global variables in the flash ram at the close of a pin.

Thank you.

I decided to directly manage the storage of variables with this code:

in the file function.h

#include "esphome.h"
#include "preferences.h"

Preferences Disco;

void setUpMemoria(){
	Disco.begin("crono", false);
	id(timeON) = Disco.getUInt("timeON",0);
	id(timeOFF) = Disco.getUInt("timeOFF",0);
	id(timeONX) = Disco.getUInt("timeONX",0);
	id(timeOFFX) = Disco.getUInt("timeOFFX",0);
	id(Temperatura) = Disco.getDouble("Temperatura",0);
	id(TemperaturaX) = Disco.getDouble("TemperaturaX",0);
	id(TempOn) = Disco.getInt("TempOn",0);
	Disco.end();
}
void writeDisco(){
	Disco.begin("crono", false);
	Disco.putUInt("timeON",id(timeON));
	Disco.putUInt("timeOFF",id(timeOFF));
	Disco.putUInt("timeONX",id(timeONX));
	Disco.putUInt("timeOFFX",id(timeOFFX));
	Disco.putDouble("Temperatura",id(Temperatura));
	Disco.putDouble("TemperaturaX",id(TemperaturaX));
	Disco.putInt("TempOn",id(TempOn));
	Disco.end();
}

in the file yaml

esphome:
  name: cronotermostato
  includes:
    - function.h
  libraries:
    - Preferences
  on_boot:
    priority: 800
    then:
      - lambda: |-
              setUpMemoria();

i don’t know if this is the best way, but i haven’t found other solutions.
