Have you tried Switch Bindings ([RELEASE] Switch Bindings 2.0) instead of the Mirror app? That is usually my go to when I want switches and bulbs to match; though, you could be right about it being a coding issue.
As for everything else, I appreciate your experiences with them. My use case is just Hue bulbs on a Hue Bridge with the Inovelli Whites in SMB. I might need to get a couple to play with and see how they function.
