Doing so both cuts down on network traffic, but also causes the lights to respond all at the same instant. However, there are limitations to this feature, and understanding exactly how it works sheds light on these. ZGM is tied to an Activator Device.

By turning on the activation device, all of them should turn on. By turning it off, all should turn off. By setting it to blue, they should all be set to blue. For Room Lights to have a group, we first need to select the group member devices in the pull down for…
