I waited now for some hours to no avail. The device was identified as
Z-Wave Node 004 (0148:0003:0001:0.16)
16 properties are populated, so I am pretty confident the discovery was successful.
If I look at PaperUI/Configuration/Binding/Z-Wave Binding I get a list of all supported things. The Eurotronics is not in the list. even though Chris wrote on Nov 7th that it has been updated for 2.5.
@chris: Could this be recurrence of the previous issue?
