VW SOC over mqtt to EVCC

[Chris87-ux]

Morning, I have a VW Passat GTEwere im not willing to pay for the VW connect solution, so I installed an OBD dongle and collect some information to my Homeautomation ( including SoC). how can I keep the Setup of the VW within EVCC and only transmit the SoC via MQTT? Is it even possible?

Could you tell more about your solution?
I'm also collecting data from our e-Golf using a BT-Dongle and a ESP32. But I would like to replace this solution with a more robust one.

I use a Teltonika FMC003 with an IoT Sim which sendint all data to flespi, from there I request the datas via api

You can use a custom vehicle.

vehicles:
  - name: my_car
    type: custom
    title: ... 
    capacity: ... 
    soc: 
      source: mqtt
      topic: ...

OK, Thanks this means I can't just set one ( SoC) value to an other sorce?

no, you can´t add it to the VW Template.
But without connection, the template is not useable any more.
