ok so I figured out the problem, the switch was using the “COMMAND_CLASS_CENTRAL_SCENE_V3” command class which means it is supposed to send the data. I thought I would enable debug in Karafe and see what debug info I could find. The Debug was great.

I noticed that the switch was in fact sending the information just as I expected it should. The problem was that OH3 GUI was rounding the number and not showing the decimal portion.
I found in a post here, that you can add metadata “State Description” to the item with a pattern of "%.1f " and it is now showing the values as I expected.
and it now shows the correct value which can be used to trigger scenes.
