Requesting support for Kamstrup Omnipower HAN-module and Aidon AMI system smart meters with "HAN-NVE" RJ45 interface.
"HAN-NVE" has a physical RJ45 port which in Sweden and Scandinavia is referred to as the "Norwegian RJ45 HAN-port standard".

Google search says that they at least sell an Kamstrup HAN-module with "HAN-NVE" RJ45 HAN interface with part number 6840004 which according to its specifications listed in the data sheet it looks like the reader needs to comply with MBUS EN-13757-2 standard as per recommendation from NVE (Norwegian Water Resources and Energy Directorate) for Norway, a.k.a. AMS+HAN version 2.0 or IEC 62056-7-5, annex D ”MBUS” slave, e.g. an IEC 62056-21 protocol mode B client.

Google also says that Aidon AMI system smart meters use the same type of HAN-NVE HAN with RJ45 port with M-Bus interface:

There looks to be some guides for parsing the protocol and getting the data through some kind of M-Bus converter here:

"The meter acts as Mbus master pushing data. To read the information, a circuit for Mbus' slave is needed."
"They are following the DLMS (Device Language Message Specification) protocol and are sent inside HDLC frames and contains OBIS (Object Identification System) codes that describe the electricity usage. Everything is part of IEC 62056 which is a set of standards for electricity metering data exchange."
