Hi @bravoleader80,
I think that you have already invested in a MIM-H04EN and Home Assistant so may not be interested in this, but some of your above CoP questions might be dealt with if you install and run NASAmonitor. This is a nice bit of monitoring software that I’ve recently been playing with, and reported on in Samsung ASHPs: Review of NASAmonitor – an Alternative to SNET-Pro2 .
In particular, it distinguishes and displays 1) current (instantaneous) CoP, 2) today’s CoP, and 3) lifetime CoP (along with their respective heat produced/power consumed figures) - all obtained by reading the NASA serial data squirted out by the MIM controller.
If your appetite for CoP data is undiminished, and notwithstanding your past investment, it might be worth your effort to install this software (and maybe a bit more hardware - requirements are described in the above link).
