Problems Configuring MQTT Cerbo GX with Home Assistant


Hello, this is my first post and my first attempt at configuring my Cerbo GX for the photovoltaic system I have installed at home, and I ask for your kindness… I’m following a YouTube video to connect the Cerbo GX via MQTT, like this one: https://www.youtube.com/watch?v=lvTGsOFsy8o.
I’m following the guide step by step, but when I try to view the data sent by the Cerbo GX MQTT broker using MQTT Explorer, no data appears as shown in the manual… I can only see the VRM number like this: N/xxxxxxxxxxxx/system/0/Serial.
Can you help me and point out where I might be going wrong?
I’m using Venus firmware version 3.13, and I also tried with the latest version, 3.55.
Thank you very much for any suggestions.
