Tuya curtain robot wifi integration

I have been attempting to integrate a Tuya curtain robot, as an alternative to switchbot.

I realise that ther have been issues in simplifying this in other discussions. However, I thought I would try a method shown in Tuya Curtain custom firmware for Home Assistant integration - YouTube.

This uses esp32 and esphome. The issue I have is I lack a basic understanding of how this would work. I can set up the esp32 and esphome fine but I don’t understand what the Tuya Mcu refers to and how I use this. My hope is it does not mean flashing the robot as I really want to avoid messing with electronics and soldering.
