DSMR integration through P1 cable

Hi,
I want my HA ( core-2021.1.5 on Home Assistant OS 5.10 , on Raspberry Pi4B 2GB) to display consumption and production data
from my Belgian ‘slimme meter’ SAGEMCOM T211 using a P1 cable.

I have no experience in yaml files but following the docs i installed the DSMR integration by editing my /config/configuration.yaml:

Configure a default setup of Home Assistant (frontend, api, etc)

default_config:

Example configuration.yaml entry for USB/serial connected Smartmeter

sensor:

  • platform: dsmr
    port: /dev/ttyUSB1
    dsmr_version: 5B

Text to speech

tts:

  • platform: google_translate

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

No entities are created, nothing visible in the main command screen.
Tried with different port numbers, without any difference
Tried with dsmr_version : 5 or 5B (for Belgian, like it should be i think)
Tried adding a set of entities like suggested in the docs:

group:
meter_readings:
name: Meter readings
entities:
- sensor.energy_consumption_tarif_1
- sensor.energy_consumption_tarif_2
- sensor.energy_production_tarif_1
- sensor.energy_production_tarif_2

==========================================================================================

This addition results in some effect: includes in the main command screen a block “meter readings” with the 4 entities, saying:
“entiteit niet beschikbaar”
Log doesn’t show any failing component…

Installed add-ons :
file editor and Motioneye
Installed integrations through GUI:
DENON, KODI, meteorologisk institutt, Mobile app, Philips Hue, Raspberry pi power supply checker, Speedtest.net, Synology DSM, Tado, UPnP

Any other suggestions/experiences are appreciated that could be useful to end this process of trying and retrying ?!?!

Hi, i found a solution. P1 ports on Smart meters under control of Fluvius (Belgium) need to be activated in 2 steps. I missed one step so no signal came from the P1 cable…
