I’ve found the attached ‘Radio Thermostat Company of America’ document of a Z-Wave plug in module. It’s not the CT101 documentation but I think the 'Association group‘ section in this document also describes how the CT101 works in regard to association configuration.
It seems that if you want to receive humidity values the user has to configure an association in the second endpoint.
Currently with OpenRemote it’s only possible to configure associations in the root device. Unfortunately this means that currently it’s not possible to receive the humidity value.
Configuring associations in endpoints for sub devices (temperature sensor, humidity sensor) will be the preferred way in the future but I’ve never seen a Z-Wave controller that supports this feature in the GUI in a generic way so far.
