Thank you, it makes perfect sense. If anything I thought it was a welcome feature of the ISY rather than a limitation. I was just trying to understand the mechanics of it and you've provided an excellent explanation. Thank you again.

... when activated individually. I'm pretty sure I'm going about this the wrong way, but I'm just curious anyway. I have replaced a 3-way setup with 2 ICON switches and set each one up to be a controller for the other (from the devices themselves). It works just fine, and the ISY properly detected the scene. However, if I use the ISY to turn either switch on or off from My Lighting, the light do turn on/off but the status of the other switch doesn't change. If I do it from the scene, it works well. The lights tell the story of the former case too. If I turn on the light on one of the switches from My Lighting, its LED goes off, but the LED of the other switch stays on. I guess it makes sense because a device can be part of multiple scenes, but can somebody explain it anyway? Is there a valid real-life use case for turning a switch on/off from My Lighting instead of turning on/off the scene it's part off? (Again I guess it you didn't want the whole scene on/off but just a single light).
