Why would this be more important to those who are migrating? I would think it would be less. When you migrate, you are ready to also include, so having both on the same page is friendlier than flipping between two screens.
From my perspective, it is an issue of intuitive interfaces and choice of workflow.
Choosing "Add Device" for an operation that removes a device is a little strange.
If it can't be in both places, perhaps a note/reminder on the z-wave details page on how to find the exclude could be added? (This would also help for the people that find old links/documentation/posts/videos/etc. that lead them to the z-wave page.)
I only see the old information in the Z-Wave Manual, which to my knowledge, has not been updated since the hub was certified on whatever firmware version that was (2.2.3 or 2.2.4?) and was probably only created for that reason.
The first third link looks up-to-date to me, and I don't see any referenecs to exclusion in the second besdies one that points to the first up-to-date document. If there are any references I'm missing, they can probably be fixed--I'm just not seeing any.
Yes, and I have seen lots of confusion and questions on the forum about this.
Here are my suggestions that should be fairly easy to implement.
Maybe my first paint edit phrasing isn't quite correct, that would probably confuse things for Zigbee and the other protocols. But possibly another more specific word could be used there? And moving it to be more prominent on the left side may also help.
To play devil's advocate, with that wording, one might assume Zigbee or virtual devices could be removed that way, too. But the general exclusion process is really specific to Z-Wave, and most devices are best removed via their device pages when possible.
