Wrong unit (kkWh) for integration sensor

Configuration
1

Hi,

I have set up an integration sensor to keep track of how much energy the electric car has consumed. I get a warning in the HA log every time at bootup that I cannot find out how to fix. Seems like the unit is kkWh (double k) even though I think it should be kWh.

Error message:

Source: components/sensor/recorder.py:259
Integration: Sensor (documentation, issues)
First occurred: 13:45:29 (1 occurrences)
Last logged: 13:45:29

sensor.energi_id4_laddning has unit kkWh which is unsupported for device_class energy

The sensor configuration:

  - platform: integration
    name: "Energi ID4 laddning"
    source: sensor.volkswagen_id_id_4_charge_power
    unit_time: h
    method: left

The source comes from an custom integration for the VW ID-family. If I look at it in the developer tools, it looks as follows:

vwid
vwid1003×186 28.2 KB

As I understand the documentation, a sensor with unit “kW” fed into the integration component to be integrated over hours, should produce kWh. However, from somewhere I get an additional k.

Any ideas how to fix this? Could it be some old configuration that has been wrong which is still “stuck” in the recorder?

Try with template sensor, convert sensor.volkswagen_id_id_4_charge_power wh to kwh:

     - platform: template
       sensors:
         general_kWh:
           value_template: "{{(states('sensor.volkswagen_id_id_4_charge_power') | float / 1000) | round(2) }}"
           unit_of_measurement: kWh
           friendly_name: "General kWh"

Another options:

- platform: integration
  source:  sensor.volkswagen_id_id_4_charge_power
  name: general_kw
  unit_prefix: k
  round: 2

I just bumped into this thread.

I am looking to read/calculate how much kWh actually went into the battery of the ID.4. Is there anyway to accomplish that?

The sensor above is, I think, limited to how much kWh went into the car, not specific into the battery, right?
