Trying to understand Start/Stop conditions of my (vallaint) heat pump

Hello all,
I’m new to this forum and I would like to start monitoring all the different “variables/parameters” of my vaillant heatpump I’ve a working ebusd where I can read all the different variables directly from the ebus with a dongle that i’ve purchased recently.

One of the 1st things I would like to understand and demystify are the conditions that make my compressor start and stop. I still don’t quite understand ….yes i’m familiar with the energy integral , compressor hysteresis , desired Flow temperature.. but there are still some unknowns to me…

Can someone point me in the right direction to start looking into all those variables in a nice dashboard ?
