Telnet is as detailed as it gets. There does not appear to be 10 devices in the Group 4 Scene.
What are the Insteon addresses of the devices that do respond and the Insteon addresses of the devices that do not.
What is the LD3 value in the four devices that do not respond. Smartlabs has changed the LD3 value from 0 to 1 but I do not think that change went back two years.
