Store data from Esphome permanently in HA? ..and read out again when booting the ESP

Hi!
I read my gas meter with a D1_Mini. The current meter reading should always be output.
When the D1_Mini is rebooted, all data is lost and it starts again at 0.
I could save to the D1’s flash (esp8266_restore_from_flash), but that’s not a good idea because of the limited write cycles.

It makes sense to store the data in HA in a variable and have the D1 read it out with an on_boot action.

What would be the simplest solution to realize this? I can’t find anything suitable for the helpers. At most the counter.

Here is the config of my D1:

esphome:
  name: esp_ecounter
  platform: ESP8266
  board: d1_mini

logger:

api:

ota:

wifi:
  
captive_portal:

globals:
  - id: total_pulses
    type: int

binary_sensor:
  - platform: gpio
    name: "Live-Impuls"
    id: internal_pulse_counter
    pin:
      number: D7
      mode:
        input: true
    filters:
      - delayed_on: 10ms
    on_press:
      then:
        - lambda: id(total_pulses) += 1;
        
sensor:
  - platform: template
    name: "Gasverbrauch"
    device_class: gas
    unit_of_measurement: "m³"
    state_class: "total_increasing"
    icon: "mdi:fire"
    accuracy_decimals: 2
    lambda: |-
      return id(total_pulses) * 0.01;

The global variable “total-pulses” should be saved. Would be great if I could sync values ​​via Home Assistant API, but if I understand correctly I can only import data from HA to ESP via this.

Hi, Have you find a solution to your problem ? thx
