How do I fix: entity sensor.9_3 (<class 'custom_components.hacs-minerstat.sensor.Minerstat'>) implements device_state_attributes

Folks,

my log throws this at me.

Logger: homeassistant.helpers.entity
Source: helpers/entity.py:574
First occurred: 18:20:37 (1 occurrences)

Entity sensor.9_3 (<class 'custom_components.hacs-minerstat.sensor.Minerstat'>) implements device_state_attributes. Please report it to the custom component author.

I reported it to github, I would fix it there and request a pull if I could, but I have no clue how to and where.

Looks like the guy is not active any more.

thanks
Manne
