I have a Aeotec USB zwave stick in my Openhab nas, then i like to add a zwave slave (raspberry pi with zwave and using zwave.me) but in my Openhab it shows up 2 Unknown nodes. And in the raspberry zwave.me the nodes are not complete in interview.
Your understanding of how this is supposed to work.
There is no such thing as a slave zwave controller meaning that it can be used in parallel with the primary one for all functions. Any device that was included with a primary controller (your Aeon stick) will store that one’s ID and will send a number of messages such as its lifeline association only ever to that primary, possibly that’s what happens when you try to interview it from the RaZberry.
There’s secondary controllers (usually remotes) to send commands but they don’t interview the network. The RaZberry (likely) cannot be used as one as it is supposed to be used as a primary itself.
