Tuya Controller

[Imtiaz]

My Windows 10 PC's Home Assistant, ESP Home VM, is finished and operating well. In addition, I updated the HA with my KC868-A16 micro controller. However, I still don't know the instructions following.

1) How can I link my PC to the microcontroller KC868-A16?

2)  In my HA KC868-A16 folder, I noticed a simple yaml file. Is it okay, or could you please tell me which one it is? Could you please advise me as to why the KC868-A16 controller was fed yaml codes?

3)  How can I use my HA to access my ports or I/O pins?

4)  Could you please advise me on how to upload a yaml file to my controller, KC868-A16?

Thanks in Advance
