Well these exact 5 sensors do not have a state_class, or they do, it is just set to None which is a legal value according to the developer documentation. More people have seen this on lots of other extensions: home-assistant/core#127363

I set them to "None" beacuse I didn't think any of the "measurement", "measurement_increasing" types make sense. But I could make them "measurement" in the sense that they represent a current value without being an actual measurement.

I will give it a thought.
