I'm happy the fix works, I'll soon post a Bugfix Release then
The main menu (at the left side) is a pure navigation menu, it can't hold any values. The states that are delayed there are cumulated from all states of buttons per page (if any button on a page would be "[on]" the whole page is displayed as "[on]")
That is to get a quick (administrative) overview without actually opening the page. This would not work with values as they can basically be anything, so how should the system know what to display in the overview when there are multiple values on a page.
In general pages are designed to serve the purpose of a category. Let's say you have a page "Lights" containing buttons for all lights in your house, you would quickly see
in the main menu if any light is on without the need to open the page.
For a general overview over your view/room I would use a dashboard; there's one dashboard per view per user. Every user can easily customize its dashboards. Dashboards can hold likes to pages (so you can use it for navigation), and actions (so you can execute your favorite features from there directly without the need to navigate anywhere)
You can also link your sensor "button" there to have some value displayed in that overview.
EDIT: If you want an overview over everything, I'd also go from a dashboard for the admin view or another view you created that consists of all items you want to be displayed.
If you want an overview over just all your sensor data, I would put them all on one page.
Btw. You can link buttons on multiple pages, so the same(! Not a copy !) button you configure on page 1 would be on page 2.
If you have problems setting this up, let me know
