Nope, the link doesn't work. But the code that link went to is 3-4 posts above yours.
I don't have the device, though, so if the driver doesn't work there isn't much I can do to fix it.
Iam looking to buy C7. But Iam wondering if anyone have make it work with Fibaro Roller Shutter 2 and Fibaro Dimmer 2?
No - I can get neither roller shutter 2 or 3 to work correctly. I had to create a rule to refresh them every x minutes as a workaround.
