Z-Stick Gen5 with Telldus TZWP-100

Hi there. I recently installed Z-Stick Gen5 and Telldus TZWP-100 to build my first automation. The Z-Stick turns up in HA at installation, but I might be stupid, but I can nowhere seem to find where to add the Telldus wall socket. Are there any good guides how to do this? I just want to get started, and setup my first timer and learn how this works.

What Z-Wave integration are you using? Legacy Z-Wave, Z-Wave2MQTT, Z-WaveJS, Z-WaveJS2MQTT?

Maybe this will help:
