There is no indication 1A.A8.B4 received the Scene On or Off sequence. Since the device can be turned On/Off it would not look like a powerline communication problem. This leaves an issue with the link records in the EZSrve or the In-Line Linc related to Unit (Group) 5. Do you have the SHN Utility installed where the link records in the In-Line Linc can be displayed?
