Currently, the logbook component provides a perspective on the history by showing all the changes that happened in reverse chronological order. Today the friendly name of the entity is being used for that. However, it would sometimes be useful to have the entity_id instead.
Concrete example, I have different motion sensors. In order to keep the frontend user-friendly, I named them all Motion Sensor instead of Motion Sensor Kitchen, Motion Sensor Bathroom, etc… This because I’m already grouping them by room so it is not useful information to add the name of the room again. In the detail of the entry, the entity_id is sometimes shown, but not always.
