So development so far for me has been fine developing clusters, but one thing that has puzzled me: clusters such as the Binary Input (Basic Cluster) or the Level Control Cluster seem to only allow for one instance of those attributes, as in I can only have one binary input, or only one attribute that has a level control. Which seems pretty strange and limiting. What if I want multiple binary attributes, like multiple device settings I'd like to toggle on or off from the coordinator, or multiple different things that have level controls, like speaker volume and LED brightness, on the same end device? I seem to be able to add multiple of the same cluster in the .zpscfg but there doesn't seem to be any way to distinguish them from one another when I want to read their attributes from a coordinator. Do I just have to make a manufacturer specific cluster and put them all in there? That just feels like a great amount of work when ZPS should make things like this pretty trivial. I just feel like there has to be an easier way.
