I think we should separate devices into 3 categories:
- New ones: they have been discovered since the last access to the page, or simply those that are not yet assigned to a room.
- Configured and functional
- Blacklist
We could see 2 possible organizations: either a single page with the 3 categories separated, or 3 pages in the left menu.
By default, I think they should be considered as sensors, this is the most « neutral » case for me. Ideally, there should be a tooltip at the top of the page specifying that some devices may be misrecognized and therefore yes, offer the status change button, only on these devices (in any case in a visible way).
