Description

It would be great to have an action that allows displaying entities in their inverted state — for example, helper entities that are not currently used in any automations, scripts, or dashboards.

This would help users keep their setups clean, organized, and efficient by easily identifying unused or redundant entities.

Use Case

Over time, systems accumulate many helper entities (input_booleans, sensors, etc.) that might no longer be in use.
Currently, there’s no easy way to find or visualize which entities are not referenced anywhere.
An inverted-state view would make maintenance and cleanup far more convenient.

Proposed Solution

Introduce an action (e.g., Show Unused Entities) that lists entities not currently used in:

• Automations
• Scripts
• Dashboards / Lovelace cards

Benefit

• Keeps setups tidy and performant
• Simplifies refactoring and cleanup
• Improves system transparency and maintainability
