Finally I did update the A16 to the last firmware of Tasmota 13.1.
Now everything is working fine, even the inputs are now in the same order, with the difference, that all now are switches.
I did compile the firmware with the option  #define USE_PCF8574_MODE2 where is possible to load a file pcf8574.dat with a template defining all the inputs and outputs as switches and relays only for pcf8574.
Now, there is no need of create rules to connect a input to an output.

Good day everyone, I am new to Kincony pcbs, I bought 2 boards but they are still on the way, to familiarize myself with my automation I installed the Tasmota BIN file firmware for KC868-A16r on an ESP32 and followed the indicated instructions. I have tried several ways but I can't get the result of seeing or configuring the PCF8574 as it is in the images.

Also support me in the YouTube video:

And even on the github page: 
https://tasmota.github.io/docs/PCF8574/ 
https://templates.blakadder.com/kincony_KC868-A16.html

But I still can't.

Could you give me a step by step?
or guide me in what I have failed?

Thank you so much

you download our A16's tasmota firmware, will see the PCF8574 option, because we have compile the firmware enabled PCF8574 function. if you use your own tasmota firmware, remember to enable it.

Thanks for the help.
I am using your version, but I don't see the PCF8574 option. The firmware is the one at the beginning of this page

after you download, you need config wifi ssid and password by board's AP.

1. download tasmota download tool for KC868-A16

2. download tasmota BIN file firmware for KC868-A16 

3. upload tasmota BIN file on ESP32


what am I doing wrong?

Use the following template:

{"NAME":"KC868-A16 rev 1.4","GPIO":[32,1,1,1,640,608,1,1,1,1,1,1,1,1,5600,1,0,1,1,5568,0,1,1,1,0,0,0,0,1,1,1,1,1,0,0,1],"FLAG":0,"BASE":1}
