If it helps to solve the problem:
Status updates from manually switching the relays do work with me as written here with the relais of Qubino “ZMNHBD Flush 2 relays”. I am running 2.1.0-SNAPSHOT Build #927 on OS X version 10.10.5. Inclusion was done with Z-Stick Gen5.
I still get lots (just cleaned out ~1700) of those “ghost” group associations in the /userdata/org.eclipse.smarthome.core.thing.Thing JSON file with my ca 10 Zwave devices as described here. I get duplicate “ghost” association entries even when just working in Habmin. This might be a connected problem, maybe?
