hm2mqtt with remote MQTT

[basti122303]

Hello,
I use a B2500D with a remote MQTT.
The Setup is like this:

B2500d -> local MQTT (remote) -> VPN -> Home Assistant
              |
    B2500d control script 
(for zero export with Volkszaehler)

The hm2mqtt config is:

pollingInterval: 60
responseTimeout: 30
enableCellData: false
enableCalibrationData: false
enableExtraBatteryData: false
allowedConsecutiveTimeouts: 3
topicPrefix: hm2mqtt
mqttProxyEnabled: false
log_level: debug
devices:
  - deviceType: HMJ-2
    deviceId: 60323bd12a9c
mqtt_uri: mqtt://USER:PASSWD@remote_host:1883
debug: true

So far so good. I see the values in the protocol.
I have only a few entries called hm2mqtt (CPU, version and so on) but not the values like SOC, load on so on.
I have no idea how to going on so can somone please help?
