Yes, please note and respect the forum policy. It is NOT on home automation and electronics in general.
I’m sure people on the forum can and are willing to help with integrating into OH once you figured out the HW part, but that you have to come up with yourself.
To speak frankly, it really takes a LOT of engineering in HW and SW to get that stuff right (and I did with my aircon so I know what I’m talking about). Reverse engineering proprietary protocols in terms of HW and SW is a real tough one.
I know you won’t want to hear that, but as you considered your own electronics knowledge to be “low”, the best advice is probably to refrain from that idea.
