Reading Smart Meter P1 port with FLM03E

I’ve been using the Flukso FLM03E for a while now with current clamps and reed sensors for water and gas. This is working fine, but I was wondering if anyone has succeeded in connecting their Flukso FLM03E port 7 to the P1 port of a smart meter (Dutch, Belgian or other)?
Should we connect the Data_RxD (pin 5) and Data_GND (pin 3) to terminals a & b of the FLM03E port 7, with 5V on the Data_RTS (pin 2)?
On the other side, the manual indicates that the firmware doesn’t support this yet:

Google shows some references of connecting the FLM02B to a P1 port, but nowhere a reference of the FLM03E.
Has anyone been able to make this work on an FLM03E? If so, how?

Experiences or feedback more than welcome!

I'm also very interested in fixing this at my homelab #KermtStroomt.

In the meantime other companies are doing what they have to do. A survey can be found on
Do we have to keep on waiting for a flukso solution or do we have to look for another system?
