Need some help

Hello. I’m using home assistant whit an Aeotec 7 usb stick and I have a small problem. Using the Z-Wave JS add on, but every time I try to add new plug, sensors they’re added unsecure, the thing that I use suport S2 security, how can I fix it?

First we need logs to tell for sure.

Second. What is the device (model number matters)

Third unless the device is participating in a security system you may not need secure connectivity.

Finally how many other ZWave devices are between your device and the coordinator (stick) and are they battery or line powered devices?
