Describe the issue

Thanks for this great integration, I was considering templates, but found this solution on time 😄

I globally disabled the creation of energie sensors as I don’t want to track that per light. Than I created a group (manually in yaml) with some lights in it. For the included lights, correctly only the power sensors are created, but for the group also an energy sensor gets created. Initially I was very happy about that as I indeed want to track energy per group. But that group energy sensor doesn’t work (remains unknown).

Based on the global setting I believe it should not be created automatically

I think it’s an other issue that when created (ie deliberate enable it for the group) it should work, even without the energie sensors enabled for its groupmembers. As the total group power is known, energy can be calculated without having energy sensors per light in the group.

Reproduction steps

1. See yaml below

Debug logs

this is logged after each restart (3 times as I created more groups)

This error originated from a custom integration.
