Automatic groups from labels

[webbson]

Describe your core improvement

I'd like the possibility to have groups (light groups in my case) that automatically add entities based on labels.

So for example I could just add the label "Window light" to my lights that are placed in windows and they'd automatically end up in a light helper that is created that is bound to the type light and label "Window light". That way I don't need to add/remove entities from multiple places when changing groups.

I usually use the labels in automations to toggle lights, but at the same time I want to have a button with the state for all "Window lights" that can be toggled manually.

Another possibility would be a "Group" card which would group together entities based on label/area/type filtering and then expose a fake entity based on the group to a underlying card like the button card. That would be good since it won't require new entities to be created for single instance use cases like one button to control multiple entities.

Current limitations

Group entities can only be built by selecting entities.

Technical benefits

• Automatic helper creation based on filtering on labels/area/types etc would make it easier to create groups of entities without having to change in multiple places.
• Simplifying managing lights in a room/role etc.
