RE: KC868-A32 configure for ESPhome - tasman - 09-09-2025
Hello. I received my new KC868-A16 (corrected from A32) today and I am having an issue installing via ESPHome 2025.8.3. This was just installed today with the latest Home Assistant build.
I am using the config posted by the user above:
esphome:
name: kc868-a32
friendly_name: KC868-A32
esp32:
board: esp32dev
framework:
type: esp-idf
version: recommended
But I am getting installation errors. Can anyone help?

RE: KC868-A32 configure for ESPhome - admin - 09-10-2025
take a photo of your PCB. do you use A32 or A32 Pro ?
RE: KC868-A32 configure for ESPhome - tasman - 09-10-2025
Sure here is a photo. My apologies I should have said A16 not A32. Thank you.

Thank you. That code is now invalid and will not install.

INFO Reading configuration /config/esphome/k868-a16.yaml...
Failed config
esphome: [source /config/esphome/k868-a16.yaml:2]

Please remove the `platform` key from the [esphome] block and use the correct platform component. This style of configuration has now been removed.
platform: ESP32
board: esp32dev
The entry at the top needs to be:
esphome:
name: a16
esp32:
board: esp32dev
However, I still have these errors on install. It has something to do with xtensa-esp32-elf-g++
INFO ESPHome 2025.8.3
INFO Reading configuration /config/esphome/k868-a16.yaml...
WARNING ? IMPORTANT: This device doesn't have a framework specified!
Currently, ESP32 defaults to the Arduino framework.
This will change to ESP-IDF in ESPHome 2026.1.0.
Note: Newer ESP32 variants (C6, H2, P4, etc.) already use ESP-IDF by default.
Why change? ESP-IDF offers:
✨ Up to 40% smaller binaries
? Better performance and optimization
? Custom-built firmware for your exact needs
? Active development and testing by ESPHome developers
Trade-offs:
⏱️ Compile times are ~25% longer
? Some components need migration
What should I do?
Option 1: Migrate to ESP-IDF (recommended)
Add this to your YAML under 'esp32:':
framework:
type: esp-idf
Option 2: Keep using Arduino (still supported)
Add this to your YAML under 'esp32:':
framework:
type: arduino
Need help? Check out the migration guide:

For readers of the forum, I uninstalled ESPHome and reinstalled, which resolved the problem.

ok, good.
