Details on preparation before installing the Integration?

[MirkoKas]

Hi,

I just found you integration and I’m very eager to try it.
I have an Axa Remote 2.0 on one place and since I switched to Home Assistant I really wanted to integrate it.

My AXA remote is powered by wire.

So what I‘m wondering: What hardware and wiring do I have to do before I can use the integration?
As far I understood:

ESP with ESP Link firmware
Some wire (?) to connect the ESP to the LIN bus which is within the Axa Remote (I guess).

Is that all?
And is there any more detailed instructions on how to do this? I‘m not that experienced with ESP and this kind of wiring….
