In theorie yes,
from what I’ve heard up until now yes, I believe it was just a firmware issue,
you can do it yourself , but you’ll need a (cheap) z-wave USB stick, and the update hex file.
The update file I might be able to get via eurotronic, but they also might recommend to trade it out for a newer version.
Let me ask my contact at eurotronic what’s best, could you send me some contact information (email or something) of yours via PM?
More users probably will have it so might be beneficial for multiple people.
