The change I made for the upcoming release was just for “quickAppVariables”. I don’t think the change I made is going to handle these label events. And it’s not only the label events either. I don’t think you are going to be able to read those on startup.
What you are asking for now is going to be a bit more challenging. If you look at how the Home Remote’s custom Attributes are set up, they are a path to a “property” value. So before you begin looking at events, you really need to find what you want in the “properties” of the main “devices” JSON, not the events. The only place I could find your labels was the “viewLayout” JSON structure. And in there they were nested several layers deep. The path to that is rather complex & not straightforward. As it is today, I don’t believe the Home Remote will be able to find that value in the JSON through its Attributes support. If possible, I think it will be in your best interest to forward those label values to a quickAppVariable. Or try to get those values forwarded to a normal property value like they were in HC2. See the pic below.

Here’s what your “properties” look like.
