For context, this is so I can get a list of unavailable entities, which I have, but I thought it would be nice to see the integration next to the entity because some are actually “offline” while others are because I’ve moved them from Smart Life to ESPHome. When doing large refactorings of my setup, it would be helpful to focus on those of a specific integration. While wishing, would be nice to be able to get the device ID and name assosciated with an entity too.
So, I really need to get the info that is in Home Assistant - this is not long term retention or anything like that where adding it as a custom attribute would be worth the time involved.
Thanks for the replies!
