Gday mate. Yes the HE is a lot to take in initially but once you get into it, it will get easier
In relation to getting your specific device into HE i'd take a look at the below link for the custom community HE driver. You will however need to flash your device to use another firmware such as Tasmota but you can find plenty of online videos on how to do that by opening it up and using the UART flash method.
