Steps
Confirm both devices support the mandatory Binding cluster (cluster ID 0x001E), required on Matter device types since Matter 1.0
On the controlling device (e.g. switch), write a TargetStruct entry to the Binding cluster's attribute list specifying the target Node ID, Endpoint, and Cluster ID
For a group target instead of a single device, set the Group field instead of Endpoint, since the two are mutually exclusive
Confirm the FabricIndex in the binding entry matches the fabric both devices share
Trigger the switch and verify it sends the command cluster invoke directly to the bound target, without controller involvement
Known gotchas
bindings only work between devices sharing the same fabric -- cross-fabric binding requires separate handling
Endpoint and Group fields in a TargetStruct are mutually exclusive; setting both (or neither correctly) produces an invalid binding entry
