[SOLVED] Strategies for unknown device?

It seems I’m getting closer to solving this. It seems that this device must be included securely for it to be successfully identified by OpenHab. For a Aeotec Z-stick Gen5 that means that it must remain in the USB-port when including and inclusion mode on the Z-stick must be All Devices.

However, one problem still remains… I still get no communication on the channels. What get is this:

2019-11-03 09:47:26.159 [ERROR] [mmandclass.ZWaveSecurityCommandClass] - NODE 34: Error decapsulating security message

Any ideas on what above means and how to solve it? I get that the key is missing, but why and how to fix it? There’s a network key in the configuration.
