DSMR in docker

I Havo installed the supervisor version in docker and I want to add my DSMR meter.
If I do this with the information on the website ,it did not work.
If I connect with the terminal and connect to the meter ,I seen the telegram what is sending from the meter.
thus that works.
My problem is that I want it imported in HA , but I can’t.
Can anyone help me?
