I recently migrated from an ISY994i to eisy with Insteon and Z-Wave devices. As part of this the Z-Wave devices' ids got changed from "ZWxxx" to "ZYxxx", for example "ZW016_002_1" to "ZY016_002_1". The new "groups" (formerly "scenes") now contain the original members with the "ZWxxx" command entries and new entries for "ZYxxx" but only as default entries so they all have to be edited to change to the correct commands. Unfortunately the commands are lost so there's no obvious way to set the new commands to the correct values. There also is no way I can see to remove the old no longer valid entry although it doesn't seem to create problems.

In the admin console run the topology report which contains the previous data
