Integration for german smartmeter (CONNEXA 3.0 - Theben)

[holgerImbery (Holger)]

Hello,
I now use TRuDi to read my metering data from the smart meter gateway. The gateway documentation mentioned a machine-2-machine interface (REST) for the HAN (home area network) side, but I could not find documentation for it. Is any other user of this hardware around with access to the M2M documentation?

Cheers

Did you manage to connect your TRuDi to Home Assistant? I’ve just learned that our Netzbetreiber offers this system too.

hey you both. Did you find anything for integrating TRuDI or HAN into homeassisant?

Hello together,
Me too, I’m looking around for a way to convince my “intelligentes Messsystem” via TRuDi to my working Home Assistant.

Two years ago I read about TRuDi and I asked EON to send me username and password for to connect to the system.
I got no answer and no information about my electrical consumption.
Last week they send me two letters with the USER-ID and my pin.

I connected the HAN Port of the “intelligentes Messsystem” with a switch in my local network, but no new device appeared in the list of connected IP nodes.

Is there anyone who could give me some advice how to use the TRuDi software or an integration in Home Assistant ?

Here ist another thread with the same topic:

Reading Energy Data from HAN Port?

Hi guys, I have already googled a bit and searched here in the community forum, but could not find a satisfactory answer so far. I live in Germany and our electricity provider has installed a LTE smart meter like this inside the electricity meter: I do not have access to most of the connections on the smart meter as they are sealed. However, the HAN port is openly accessible. If I have read correctly, real-time data on consumption is also provided via this HAN port. Unfortunately, it seems …

I found the manual on this page and in this PDF: CONEXA 3.0 AGD-LV v3.80.x.pdf.

On page 23 they write this (Translated with Deepl):

The devices and tools required by the end user to connect to the SMGW at the HAN interface are listed here:

• A PC or tablet with a freely configurable network interface (LAN), alternatively this can also be configured in advance
• IP address of the SMGW (this is provided to the end user by the operator/user)
• A standard web browser (e.g. Mozilla Firefox) for access via a web browser
• A REST client for accessing the M2M interface, such as Postman (https://getpostman.com)
• A standard LAN cable (Ethernet cable)
• A connection between the PC or tablet and SMGW must be established. To do this Plug the Ethernet cable into the free Ethernet socket on the PC and into the HAN interface on the SMGW
• The network connection on the PC must be configured as per E-3.
• As an alternative to a REST client, a reference implementation of an end consumer tool (TRuDI) can be obtained from the manufacturer or the Physikalisch-Technische Bundesanstalt (PTB) (see chapter A-10).
• The connection between the end consumer and the SMGW is protected by cryptographic mechanisms. Transport Layer Security (TLS) version 1.2 is used here,
• All programs used by the end consumer to communicate with the SMGW must support this protocol.
