The loxone config files use different terminology for almost every setting than what is presented in the UI, which of course makes file level investigation a pain in the ass.
Combined with the very esoteric HVAC settings, hidden connections, and the rest, make it even more opaque
A simple example - TDiff - it maps to acceptable deviation when you have a single temp setting; but in practice what I have seen is it seems to actually be the threshold value to switch modes and the system actually tolerates very little actual deviation from the set temp. Either some other parameter is confounding the picture, or the description is poorly written...
I am slowly putting together my own, but honestly if someone has already done the work somewhere, I would obviously rather skip that tedium and just get my house working properly.
