Update ESPHome-Firmware 2023.12.9 -> 2025.10.1

[Nobby888]

Hi Community,

friend of mine had ordered a Tiny House and long story short: she was left alone with her automation in HomeAssistant.

First Problem:
- she got screwed with the server. HomeAssistant-OS (HAOS) didn't work and we couldn't reinstall it, because the PC was toast. So we ordered a new Mini-PC (with an Intel N150, 8GB Ram and 500GB NVMe-SSD) and installed HAOS (Version 2025.something) and HACS. We installed the Backup-File (stored on Google) and because there was already a version-gap from 2023 (the time they originally installed HomeAssistant) and 2025 (the time we are trying to fix it) I wanted to update the whole system and the modules in HAOS.

And now the probelm:
I want to update the ESPHome firmware of the KC868-E16S over OTA. Because of the Version-gap between ESPHome-Builder and the Frimware of the relay-module the integration doesn't work properly in HAOS.

Hardware: KC868-E16S
The Version of ESP Home Builder: 2025.10.1
The Version of the ESP Home Firmware 2023.12.9


I found out, that there are a lot of changes over the time, so I already made some changes in the original YAML-File (see attachet):
- adding on OTA: platform: esphome
- changed "dallas" to "one-wire"
but I could not make an OTA.

After trying to make an OTA I get the attachet message.
   

Please help! What am I doing wrong? What am I missing? Could you please correct the YAML-file?!
And please avoid: "Why did you update?! Never touch a running system ... well, it wasn't running and I like an up-to-date-system"

Thank you so much for your help!!
