[solved] Errors when removing/adding 'platform'

ESPHome
1

I’m trying to update devices from v2024.4.2
This is the current config:

esphome:
  name: ${device_name}
  comment: "${device_description}"
  platform: ESP8266
  esp8266_restore_from_flash: true
  board: d1_mini
  name_add_mac_suffix: false
  on_boot:

and

ota:
  password: <redacted>

If I add platform to the ota section I get an error for the one under esphome and if I remove that one, I also get an error… :thinking:

So I have no clue how to continue… :blush:
TIA

Nobody else has a clue either unless you say that the errors are.

The platform: key under ota: is a requirement now. If you omit that the build will stop at that point, masking the other unspecified error.

So read the docs and do what the message said.

esp8266 is a top level key, it doesn’t go under esphome:. The format you were using was deprecated over three years ago and removed completely nearly a year ago.

Hi, thanks for pointing that out but I get 1 error after the other when I try to correct this and TBH I’m not that good in this.

The original configuration came with that setup and just now I thought of updating it.

Thanks Tom, this worked! :+1:

I didn’t know where to put what under those top levels. :bowing_man:
