Getting started with KC-868AG Pro for blinds control with ESPHome/Home Assistant

[Parallax Abstraction]

what you want to do with AG Pro, such as IR device? TV , air conditioner? or some others?
need your requirements in details. AG Pro mainly config by ESPHome, the ESPHome yaml file as same as AG's yaml file.

For now, the only thing I want to control with it are some powered blinds, which use a remote control that operates at 433Mhz. I want Home Assistant to be able to control them based on time, lighting conditions and some other factors. I just need to have the AG Pro learn the remote's commands and then be able to broadcast them to the blinds. ESPHome is the perfect way to do that, but I don't know how to set it up as there's very little documentation. From what I understand, the device has to be flashed with a firmware before I can connect it to my wi-fi. I've got the UART driver installed and my PC can see the device, but I can't find the latest firmware for it. Every firmware I can find says it's for another model. Once I do flash it, I assume the YAML file is where I enter the settings for my wi-fi network? What YAML file would I use for this model?

Thanks.
