Can't add ZWave devices


I’m new with HA. I have a running Vera Plus with several Zwave devices. I want to switch to HA.
Installation went fine on my Pi3. Several integrations were found after installtion (Hue, Tado etc.)
My Aeotec Zwave stick was also found. But what next?

I have reset a Smart Switch 6. It should be ready for inclusion in HA. But HA finds nothing when I try to add a device.

I can see a lot of dead nodes. Don’t know what they are. Probably my connected zwave devices in Vera Plus?

What must I do to include a new device in HA Zwave?



Thank you.
The problem was my second hand Zwave stick. It was not reset completely.
