Network key location

Configuration
1

Does anyone know the difference between placing the network key within the configuration.yaml file vs the options.xml file. Moving it to the options file seemed to resolve some issues for my zwave.

Is there scenarios where to place it in one vs the other?

Well the options.xml file is used directly by openzwave. As the configuration.yaml is used by HA and the integration will pass along the key to openzwave. So the options.xml is a more direct route to the actual interface. Afaik.
