Fibaro wall plug 2 not secure

My fibaro wall plug 2 always adds as not secure (see screenshot). I’ve tried factory reset and add again but it stays insecure
how can I add it secure?

Why do you want to connect it especially secure?
Just a question.

Maybe ask your question in this topic.

why not? i was under the assumption that it has the functionality

Z-wave devices with only Secure S0 (like the wall plug 2?, not sure if that is the correct naming), it will always include unsecure in Homey as the latency was too big in some (a lot) situations.
