Recommendations for 'measurement' which is impossible considering device class ('energy') ?

[mild kernel]

Hi, in my log I see the following warning which indicates incorrect sensor configuration. I know the sensor configuration come from the addon "HoyMiles Solar Gateway stable Addon" - a Hoymiles cloud to MQTT transformer. So I opened a ticket in the addon repo instead of open a core issue. But now the maintainer asked how to fix. Does anybody know about details / recommendations how to fix?

as it is energy sensor, it should be 'total' or 'total_increasing' preferably, afaik.
