I'd say it is to include a Z-wave sensor. If I remeber correctly there are Z-wave you are working with in this case?
1: Log in to IoT Open
2: Klick on the link to Workbench on the home-page.
3: Choose the correct installation
4: Under "Misc" you have Z-wave commands.
5: Start inclusion* and do the magic clicks on your sensor.
*) If the sensor have been included in another network it might be wise to exclude it first. Then start exclusion and do the magic clicks before you do the inclusion.
