To make this work, first create a new integral helper under settings -> devices -> helpers.
don't set it to kilo, as the data is not W but kW already
Then overwrite the helpers data, so it appears in the device list.
For this install the https://www.home-assistant.io/common-tasks/os/#installing-and-using-the-file-editor-add-on[File Editor addon]
Then open /homeassistant/configuration.yaml and write:
homeassistant:
customize:
sensor.wp_verbauch_kwh_ohnekilo:
device_class: energy
state_class: total_increasing
unit_of_measurement: kWh
