Hello!

The KC868-A128 can be integrated with MQTT in Home Assistant?
I'm using this firmware version for  KC868-A128:  v1.0.27.
If yes, what are the steps and the configuration lines in the "configuration.yaml" file in Home Assistant?

Thank you!
sure, A128 can integrate to home assistant by MQTT. there is demo code for A8S, but A128 is same:

but i suggest you integrate to home assistant by ESPHome, it's easier, here is yaml:

yes, it is true that through EspHome it is easier. I'm interested in keeping this position as well "KCS" v1.0.27 firmware for KC868-A64 A128
Hello!

We used your configuration lines, it's seeing the device in HA, but it cannot control it. No feedback from device.
We used this lines:
Code:
mqtt:
  switch:
  - name: 'bunica-01'
    unique_id: bunica-01
    state_topic: 'KC868_A128/D4D4DAE11FE8/state'
    command_topic: 'KC868_A128/D4D4DAE11FE8/set'
    payload_on:  '{"output1":{"value":true}}'
    payload_off:  '{"output1":{"value":false}}'
    value_template: '{{ value_json.output1.value }}'
    state_on: true
    state_off: false

What is wrong here?
See also the screen captures.
"broker address" should input mqtt://192.168.1.102 you not input "mqtt://"
in the YAML file to make this change or in the A128 board?

I tried this in the a128 card but with the same result. I see the button created in HA, but nothing happens when pressed

here.
post your yaml file at here.
it is posted above as a picture

and the file
state_topic: 'KC868_A128/D4D4DAE11FE8/state' wrong
command_topic: 'KC868_A128/D4D4DAE11FE8/set' wrong

should be

state_topic: 'KC868_A128/D4D4DAE11FE8/STATE'
command_topic: 'KC868_A128/D4D4DAE11FE8/SET'

"state" and "set", should be Uppercase。
Thank you. It is solved, it works.
but one more question.
To be able to see the input. is it another line of code?
