I think it would save time and effort that when an item supports UUID then HASS creates automatically one for the item if it doesn’t exist.
Doesn’t harm and eases life when you want to modify something at the UI
Where the integration supports it, that’s done.
If it’s not done then either:
- The integration hasn’t been updated for this, but can support it - this “just” needs somebody willing to invest the time and effort into updating it
- The integration can’t support it (there’s no way to uniquely identify the device). It might be possible with updates to the upstream library, but would require somebody to investigate this and make the changes required there first.
- It’s configured in YAML
