If this card re-renders on every state change, it is re-rendering like crazy on big instances. This causes browsers to eat battery and kills performance.
I suggest that either re-renders are debounced if no entities are specified (ie max render once a second) or that leaving entities to track out of your config will cause it to not re-render at all.
