on_boot not working

[ageurtse]

i hope you could help me out.

i liked the setup you use for your devices, so i'm tring to replicate it.
Almost everything is working, but the on_boot event isn't fired and there for i don't get my values from my external memory module.

do you now why on_boot isn't working ?

below, a piece of my code from the device i build.

substitutions:
  system_name: 101-test
  friendly_name: Test
  device_description: "Test sensor to see off all paths are right."
  static_ip: 192.168.1.101

packages:
  device: !include devices/d1_mini.yaml

esphome:
  on_boot:
    priority: 800.0
    then:
      - lambda: |-
          readcounters();
          ESP_LOGI(TAG, "on_boot read");
