How to use tasmota for KC868-A16 via PCF8574 IIC extend GPIO

[GabrielRR]

sure, you can download newest tasmota (include MATTER). we already have a video tour, use tasmota MATTER firmware in KinCony KC868-A series ESP32 board. here is video tour:
https://youtu.be/K9PMHzNPySI    MATTER for Apple homekit
https://youtu.be/lb6V9-gQmII      MATTER for Amazon Alexa

It's not working.
I put the template but PCF8574 IIC doesn't appear in the menu. 
The blackadder repository only haves the version 1.4 and the board is the version 1.6

you can compile the newest tasmota firmware online, just enable "MATTER".

I can't flash the evice with tasmota after compiling it gives me an error in loop:

When I flash your firmware is ok.

Can you help me?

Which template for tasmota should I use:

1) The original:
{"NAME":"KC868-A16","GPIO":[32,0,1120,0,640,608,0,0,0,1,1,1152,0,0,5600,0,0,0,0,5568,0,0,0,0,0,0,0,0,1,1,0,0,1,0,0,1],"FLAG":0,"BASE":1}

2) The one in Blackadder site:
{"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}

3) A new one since the board you sold me is R1.6

I need to be sure what template should I use!!!!

why you not download tasmota bin directly to use? all BIN file support MATTER now.
just download to ESP32, then set I2C bus SCL,SDA pin for A16 board.

Thank you for your answer.
Yes, now matter is a default feature, Thats  is solve.
 But anyway I need to compile PCF8574, which doesnt come on that pre compile binary.

https://tasmota.github.io/docs/PCF8574/

So I need the template anyway.

you can compile by tasmota online webpage: enable MATTER and PCF8574 function.

I already did, it works.
But I need the template of the board for tasmota, mine is R1.6

I did a lot of research and finally everything is working, almost perfect.
I put the latest version of tasmota, I've created rules to control outputs with the input buttons. Now its ok.
However it happen that the inputs are somehow out of order.


   

Meaning that the physical ports that you have in A16 board are changed compared with the digital inputs in tasmota GUI.

How do I change this?

i think need modify setting before compile tasmota firmware.
