P1 cable NUC HA OS - connect with DSMR

Configuration Frontend
1

Have Home Assistant OS running on my intel NUC, using virtualbox latest version as well as HA.

P1 cable is plugged in and in my virtualbox I ported it to COM1 serial.
Since it’s showing up in HA I think I’m almost there

I do think that "s/n:n/a " suppose to be a number over there, which I might should configure. correct?

I’m quite sure the p1 cable is correct and should work for my meter.
I checked a lot of other topics by they all are shown “ttyUSB” or something related so I guess I have a different situation.

please help, and thanks for reading already.
BR, Frank

Got DSMR enabled finally.
Used a different COM port and used DSMR version 5L (not idea why it worked).
I know I have EMSR5 as electricty meter.

But now…
I don’t see any values yet, do I still need to configure the incoming values somewhere? Really don’t have a clue…
