I've upgraded from 0.24.1 to 0.25.0 (so the integration was upgraded not freshly installed) and I have the following error during the initialization of the integration:

Traceback (most recent call last):

    async_add_entities(_create_sensors_for_charger(chargerName, hass, config[CONF_CORRECTION_FACTOR]))
KeyError: 'correction_factor'

When trying to edit the configuration in the backend, following error message is shown:

The response of the related XHR request looks the following:

The failed flow initialization is logged in the backend as well:

The problems are related to the recent changes regarding correction_factor configuration variable.

[cathiele]

Please test version 0.25.1

[stepir]

@cathiele now it works - can you please advise how the factor should be used (guess it should be a factor, so 1.07 would increase the read value by 7%)? the input box during setup is kinda bugged

[temesinko]

@cathiele Integration itself works now and initializes correctly, but the config flow (in my case after upgrading, not a fresh install) is still broken. I'll have a look at this tonight.

[cathiele]

finally i had time to fix it. 0.25.2 should have a working config flow.

Older Chargers, like mine V2 charger, have incorrect power calculations. mine is way to low. So with setting the correction factor to values other than 1.0 you can correct the api values by a factor. the uncorrected values are still available as the original attributes.
