EVCC custom MQTT charger or meter

Third party integrations
1

I use the EVCC addon GitHub - evcc-io/hassio-addon: Hass.io add-on for EVCC plus the integration. For my charger I need to have a MQTT communication between EVCC and Home Assistant, but so far I couldn’t get it to run. Simple meters over MQTT do run!

I opened a ticket in the EVCC Forum but it is still not clear what I am missing.

Has anyone successfully got a working Custom MQTT charger setup in Home Assistant?
Here are my charger settings in evcc.yaml.

chargers:
  - name: Carport
    type: custom
    status: # charger status A..F
        source: mqtt
        topic: evcc-hass/sensor/ev_charging_status_evcc
        timeout: 10m
    enabled: # charger enabled state (true/false or 0/1)
        source: mqtt
        topic: evcc-hass/chargers/charger1/ChargePointEnabled
        timeout: 10m
    enable: # set charger enabled state (true/false or 0/1)
        source: mqtt
        topic: evcc-hass/chargers/charger1/ChargePointEnabled
        payload: ${enable:%d}
        timeout: 10m
    maxcurrent: # set charger max current (A)
        source: mqtt
