No statistics found.

Version of the custom_component

2.0.1

Describe the bug

When an entity from this component is added to a statistic graph, all stat types are grayed out and the graph displays No statistics found.

Adding this to extra_state_attributes seems to fix the issue:

'state_class': 'measurement'

Thanks for this, I'll take a look when I get some time
