Hi Andreas,
I do use the Qivicon ZigBee Stick and was able to connect these two devices you mentioned. They show as online in PaperUI but I do also not get any channel to use them. Would be nice to control my lights by this little Cube and Wall Switch. For my devices it is the same model ID as you mentioned above.
Think they are not supported yet by ZigBee Binding. Would be nice to see in the future!
Regards,
Jan
