There is an entity for wallbox consumption (kW), but the entity for the total consumption (kWh) is missing.

This is the only entity missing for me to switch from my previous e3dc interface to this integration. There is also more detailed data available (kWh solar / net), but for me the sum is already enough.

Describe the solution you'd like

A new entity for wallbox_consumption_total (or _today) is available.

Describe alternatives you've considered

A Riemann integral would technically be possible.
Using another interface to get the data like before would be the another valid option.

Additional context

Currently I'm using the go-rscp command line utility by @spali (https://github.com/spali/go-rscp/). I can get the wallbox data with these keys:

  [ # day current
    "DB_REQ_HISTORY_DATA_DAY",
    [
      ["DB_REQ_HISTORY_TIME_START", some nonsense ],
      ["DB_REQ_HISTORY_TIME_INTERVAL", more nonsense ],
      ["DB_REQ_HISTORY_TIME_SPAN", guess ]
    ]
  ],
  [
    "WB_REQ_DATA",
    [
      ["WB_INDEX", 0],
      "WB_REQ_ENERGY_ALL",
      "WB_REQ_ENERGY_SOLAR"
    ]
  ]
]

Diagnostics dump

I think this data is still missing from the library you're using, so I updated a feature request there with some additional data.

@derhappy I'll look into this. One thing, could you send me a diagnostics dump when your WB is loading? I've not yet seen how the existing API reacts if the WB is active. Please attach it to #54. That would be cool!
