For any specific Scene, where Device A is the Controller, Device A cannot also be a Responder. Insteon hardware does not support a given device as being a Controller and then also a responder of the same Scene.
When a device is a Controller of a scene, it has a “Controller of” link record in its link database for each responder device associated with the scene. Each Responder device has a “Responder to” link record in its link database reflecting the controller Insteon address and the Bright level and Ramp rate the Responder device should use when responding to a command from the Controller. There is no mechanism in the Insteon architecture for a Controller device to have a “Responder to” link record for the scene that the Controller device is initiating. Certainly a Controller can be a Responder and have a “Responder to” link record but it would a Responder to some other physical Controller device, not itself as the Controller.
The link pattern below is valid and is a normal cross-link sequence where two Insteon devices are operating in a Virtual 3 way circuit. When Device A is a Responder, Device B is the Controller. When Device B is the Responder, Device A is the Controller. Device A is never a Responder to Device A and Device B is never a Responder to Device B.
