Sorry for the delay, I was checking some details with the engineering team.
The implementation of creating separate LAN devices as part of a Zigbee/Z-Wave driver isn’t suggested as the ability to perform this particular action may be removed in the future, so, please, use it at your own risk.
The team is aware of the requirement of supporting the “parent/child” model for Zigbee/Z-Wave and will be analyzed later on.
