As I wrote in my other post, I connected the push button switch module to rs232 to the LAN converter, I would know if it is possible to change the push button switch module firmware to get a message every time I press and leave a contact from the input like in your video (https://www.kincony.com/momentary-latch-...n-diy.html)
If I press and hold a button I receive RELAY-KEY-255, X, 1,
If I release the button I receive RELAY-KEY-255, X, 0

do you think is possible?
thank you in advance

Thanks for zgabi from Hungary made the document for KC868-H32B integrate with Loxone by RS232.

improvement:

mainly support integrate to Loxone Mini-Server by RS232 port.

1. after INPUT trigger (when released input with GND) will auto feedback "DIARM" message to TCP client and RS232.

such as if you let INPUT short with GND, will send "RELAY-ALARM-1,OK" , that means: INPUT-1 is trigger.
when released, will send "RELAY-DIARM-1,OK" , that means: INPUT-1 is released, just "disable alarm".

2. It supports sending multiple control relay commands to the KC868-H32B at one time by RS232 or TCP. The controller will process them in a queue without discarding the commands. At most, MAX 32 commands can be received at the same time

such as you can send these command at one time by RS232 or TCP:

download the ZIP file , unzip update the bin file for KC868-H32B relay controller by USB-RS232 cable.

1. install ESP32 USB driver for KC868-Server, download from: https://www.kincony.com/download/CH341SER.zip

2. install ESP32 USB driver

3. download arduino IDE: https://www.arduino.cc/en/software/

4. install arduino IDE

5. config for ESP32: https://www.kincony.com/forum/showthread.php?tid=281

6. install rc-switch arduino library

7. download this RF / IR decode demo source code: 
  KC868-Server-wireless-decode.zip (Size: 3.89 KB / Downloads: 959)

8. detect your RF or IR remoter's key code

9. replace your own RF or IR remoter's key code

10. download firmware to KC868-Server by TYPE-C USB cable

1. switch panel type: momentary.

2. button wires to KC868-Server's digital input ports.

3. LED indicator wires from KC868-Server's digital output ports.
   

4. double click function define for key buttons:

key1: ON 3,4,5,6
key2: OFF 3,4,5,6
key3: invert 3,4,5,6

5. momentary time:

relay4: 1 second
relay5: 5 second

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:
