Issues with restoring to the previous state after updates and power outages.

[WiZaR5789]

Hi, do you have any thoughts on how to make an ESP32 (flashed with ESPHome) retain its state after a restart? Currently, with each update or power outage, I have to set the brightness and color from the beginning. If this is a straightforward question and I should know the answer, please point me in the direction where I can find it. Below, I'm providing YAML with code for ESPHome, which I am using.

You are looking for a feature which is missing in ESPHome as far as I know. At the moment only the state (on/off) of a light entity can be restored easily. This doesn't include the brightness and color/colortemp.

[WiZaR5789]

Do you have any idea how to bypass this, or do I rather need to learn to live with it and that's it?

[syssi]

I've extended all my automations by the expected default (colortemp + brightness):

  action:
    - service: light.turn_on
      entity_id: light.nursery
      data:
        brightness_pct: 100
        color_temp: 370

In this case the previous state of the light doesnt matter anymore. Sometimes I've a input_number per room to be able to pick up some easily configurable defaults:

  action:
    - service: light.turn_on
      entity_id: light.nursery_nightlight
      data_template:
        brightness_pct: "{{ states('input_number.nursery_light_brightness_double_click')|int(1) }}"
        color_temp: 370

# ...

    - service: light.turn_on
      entity_id: light.nursery
      data_template:
        brightness_pct: "{{ states('input_number.nursery_light_brightness_single_click')|int(100) }}"
        color_temp: 370

This is another workaround to manipulate some settings on boot to avoid unloved states:

# https://github.com/syssi/philipslight
esphome:
  name: "${hostname}"
  platform: ESP8266
  board: esp_wroom_02
  board_flash_mode: dout
  includes:
    - common/custom_components/xiaomi_light.h
  on_boot:
    then:
      - light.turn_on:
          id: bulb
          brightness: "$brightness_on_boot"
          color_temperature: 333mireds

Please don't copy&paste the complete code block. The on_boot section is the relevant part for you!

[WiZaR5789]

It's some idea, thanks. I'll probably go with the second option.
