If you have a Fibaro Dimmer 2 and it is showing the scenes in the Trigger UI, then please use the Edit Device Settings dialog and press the Write To Log button (and copy/paste the results into a reply for me).
Likewise, if you have a Fibaro Dimmer 2 and it is not showing the scenes in the Trigger UI, then please use the Edit Device Settings dialog and press the Write To Log button (and copy/paste the results into a reply for me).
I think the problem is some some Dimmer 2's are using a different model ID for which Indigo doesn't have any device definition. If that is the case, I'll duplicate the existing definition so that at least the scenes will show in the Trigger UI. But first I need to get an understanding of which model IDs you all have and need to know if that particular model ID is showing the scenes in the Trigger UI or not.
