Adding a new device in 2024 to ESPhome the new entities get the device name added to the front of them.
Old ESPhome devices did not seem to do this.
Does anyone know how this is determined?
I think it has something to do with specifying a friendly_name and also giving your entities a name as well.
This has been discussed several times on here. Theres no shortage of posts you could look at by just using the search feature. Thats what its there for.
But if you update the old devices to at least the latest ESPHome version then they all get renamed as well.
I ran into this recently during my “every-two-year-esphome-update” session when I noticed all my entities changed. I had to go thru all of them and fix them.
