Hi!
Some of your current configuration is already outdated (eg. tunneling:) so you might have looked at an outdated source for reference - see KNX - Home Assistant for most current documentation.
There are some projects aiming to import from a .knxproj file, but I don’t know about the results they yield. See GitHub - laurent-martin/ets-to-homeassistant: script to convert ETS5 project file to a YAML configuration file suitable for Home Assistant
Imho it’s better to do it yourself to understand the semantics and get to know the possible options each platform has. The rest is just cooy&paste. HomeAssistant VSCode Plugin is also a good help (but currently also a bit out of date).
PS: please use code tags (```) for yaml.
