Hi Folks,
just to let you know, because i didn´t get any answer, i finally realized the connection from my VIMAR By-Me Plus System with Home Assistant.
The solution is to install a dedicated IP Interface. From there you just need to use the translated HEX Adresses of your Vimar System and you are ready to go. I use this one: Amazon.de
To my understanding every other IP Interface should work. In my case it was not even necessary to program the Interface with ETS, it just worked out of the box and was found from HA immediately.
Best, Christian
