KC868-A16 into Home assistant via MQTT

[Ugeo]

Please help us create the integration of KC868-A16 into Home assistant via MQTT.
Home assistant does not see data from KC868-A16
   

[admin]

this is KCS mqtt document: https://www.kincony.com/forum/attachment.php?aid=2872

If using KC868-A16:
Command topic: KC868_A16/B48A0A404664/SET
State topic: KC868_A16/B48A0A404664/STATE

the ID replace by yourself. Now your topic is wrong.

here is demo code for A8S: https://www.kincony.com/forum/showthread.php?tid=3274

I did everything according to your example. (switch:-output 1) works fine. But "input1" is still in the "unknown" status. Please send an example for KC868-A16 and specifically for (binary_sensor: -"input1"). I would appreciate it.

Inputs are not working because of these bugs !

There are bugs in MQTT message in version 2.2.5. Reproduced on A8 and also A16.
1. Missing coma after last input and before first output, example:
... "input15":{"value":false},"input16":{"value":false}"output1":{"value":false}, ...
2. Missing coma after last output and before first adc, example:
... "output15":{"value":false},"output16":{"value":true}"adc1":{"value":0}, ...
3. Missing coma after last adc and before first sensor, example:
... "adc4":{"value":0}"sensor1":{"temperature":-100.0,"humity":-100.0}, ...
4. Typo error on sensor humidity name, example:
... sensor1":{"temperature":-100.0,"humity":-100.0}, ...
instead of: ... sensor1":{"temperature":-100.0,"humidity":-100.0}, ...

MQTT is not working in version 2.2.5 because of these bugs.

Will work for you with updated KCS firmware! not 2.2.5

[admin]

we will update soon.

KCS v2.2.6 uploaded. Download this new firmware will solve your problem.

Today I installed new firmware 2.2.6  (thanks) and now outputs are working fine: 
they can be managed from HAOS (also in 2.2.5) 
and follows status change (fixed with 2.2.6). 
The problem remain on Inputs, I cannot see any status change and they are always in "unknown" status. 
I tryied many options, finally I found the working configuration for inputs:

mqtt:
  switch:
    - name: "a161-kcs-output-1"
      unique_id: a161-kcs-output-1
      state_topic: "KC868_A16/XXXXXXXXX/STATE"
      command_topic: "KC868_A16/XXXXXXXXX/SET"
      payload_on: '{"output1":{"value":true}}'
      payload_off: '{"output1":{"value":false}}'
      value_template: "{{ value_json.output1.value }}"
      state_on: true
      state_off: false

binary_sensor:
these are wrong:
      payload_on: '{"input1":{"value":true}}'
      payload_on: "true"
      payload_on: true (Incorrect type. Expected "string")

this is working for me
    - name: "a161-kcs-input-2"
      unique_id: a161-kcs-input-2
      state_topic: "KC868_A16/XXXXXXXXX/STATE"
      value_template: "{{ value_json.input2.value }}"
      payload_on: "True"
      payload_off: "False"

ok, thanks share your code. that need use "True" , not use "true". do you using with KC868-A16 board?

[Labesanella]

I bought two A16 and I am doing tests to decide if it's better to use EspHome or your firmware and MQTT linked to Home Assistant. Now I saw that also MQTT is working so I think that it's better to use the KCS firmware and MQTT because some inputs must close a relay without delay or error otherwise I can have dangerous problems. With KCS and IIF I don't have delay and I'm sure that the relay is opened. Please, if it's possible, I'have a question about outputs: how is the maximum load for these MOSFET ?

[admin]

the MOSFET MAX10A, but you can't use every channel with full 10A load, MOSFET is no problem. The PCB wire and terminal will not enough for that. Because every 8 channel load's Power Voltage is together by one terminal port.
