this is sample diagram for 8 gang switch panel with KC868-Server and feedback output state for LEDs.
   

if want to read output1 by http command, here is url:
http://10.10.10.135/cm?cmnd=Power1%20state        will feedback: {"POWER1":"ON"}

if want to read output2 by http command, here is url:
http://10.10.10.135/cm?cmnd=Power2%20state        will feedback: {"POWER2":"OFF"}

this rules sample will set KC868-A16 input1 toggle output1.

for example if input1 -- toggle --> output1:

rule1 on PCF8574-1_INP#D0=0 do power1 toggle endon
rule1 1

if input2 -- toggle --> output2:

rule2 on PCF8574-1_INP#D1=0 do power2 toggle endon
rule2 1

if input3 -- toggle --> output3:

rule3 on PCF8574-1_INP#D2=0 do power3 toggle endon
rule3 1

here are setting photos for sample rule1:

   
   
   
   

I was told to post here what I am trying to do. My parts are:
1. K868-H32L
2. Tp-link wireless router
3. ESP8266
4. Old PC

Scenario: I tried using the ESP8266 with the K868-H32L to link to Alexa. However, Alexa could only detect 10 switches out of the 32. Kincony notified me that ESP8266 is only limited. Now, I have a bunch of OLD PCs lying around with ready windows. Kincony told me I can use PC with red NODE. I managed to install and sign up for red-node. Again, Kincony support told me that I cannot use MQQT with K868-H32L. I am posting here because I need help how to set-up red-node using TCP-out.

The videos posted are MQQT are very similar to TCP-out. I followed it however, TCP-out would not connect to my 868-H32L, I connected PC and H32L relay to LAN of wireless router, Internet access thru WAN of Wireless router, Alexa module connected to Wireless Router. Everything is working with the KC868-H32.exe pc software so I know parts are working.

I need to automate the system via Alexa. Kindly assist how to connect 868-H32L relay to red-Node via TCP-Out. The programming of Alexa to red Node is already in the MQQT videos.

switch:
  - platform: mqtt
    name: 'output-1'
    unique_id: output-1
    state_topic: 'server/ xxxxxxxxxxxxxxxxxxxxxxxx /state'
    command_topic: 'server/ xxxxxxxxxxxxxxxxxxxxxxxx /set'
    payload_on:  '{"relay1":{"on":1}}'
    payload_off:  '{"relay1":{"on":0}}'
    value_template: '{{ value_json.relay1.on }}'
    state_on: 1
state_off: 0


binary_sensor:
  - platform: mqtt
    name: 'input-1'
    unique_id: input-1
    state_topic: 'server/ xxxxxxxxxxxxxxxxxxxxxxxx /state'
    value_template: '{{ value_json.input1.on }}'
    payload_on: 1

sensor:
  - platform: mqtt

    unique_id: analog-1
    state_topic: 'server/ xxxxxxxxxxxxxxxxxxxxxxxx /state'
    unit_of_measurement: 'v'
    value_template: '{{ value_json.analog1.value }} ' 

Note: xxxxxxxxxxxxxxxxxxxxxxxx is UID of controller, just replace with your device UID. You can find the UID in ethernet setting.
