Personally I don’t use the portal because it offers less functionality than the mobile app, and I always have a mobile device with me, or a voice assistant close by, but regardless, here’s my perspective of the portal so far:
I’ve seen my mobile presence sensors there for a very long time, perhaps from the very beginning of release of the portal.
I’ve noticed some speed improvements, but there are still issues with device states and capabilities. I have several devices in the portal that are in an “unknown” state, but the mobile app is fine. When you look at a device in the portal with an unknown state, most of the capabilities say “undefined”, but again work fine in the mobile app.
The device tiles now look like they do in the new mobile app. I’m not sure when that changed, but there was a difference for quite some time.
You CAN NOT MOVE around Rooms in the Dashboard view, AND you can’t move around devices within a Room in the Dashboard view. This drives me crazy.
You CAN NOT MOVE devices around in a Room, even within the Rooms view, but you can drag and drop devices between Rooms and you can drag and drop devices to/from the Favorite section at the top of the Room. You still can’t arrange anything, which looks like it’s automatically sorted by device name, and if you put something in the Favorite section, it doesn’t show up in the same order in the Dashboard view as is does in the Room view.
Moving around Rooms in the Rooms view is very clunky. When you move a Room to where you think you want it, all the other Rooms around it shift in all directions based on the size of Room (I think). Arranging Rooms is a useless endeavor if you like any sense of order in your stuff.
The Automations “tab” does not show Automations that you can see in the mobile app. All that’s there are Scenes (only to move around into your favorites that show up in your Dashboard), and Groovy SmartApps.
