some news from the Z-Wave front: A danish company (seluxit.com) produces the ViaSENS Homecontroller. It's a european version (868MHz) usb device. Daniel Lux from Seluxit provides me with a test sample. It should be accessible via /dev/ttyACM0 (cdc-acm module).
They also are thinking about some encapsulation library for linux for the z-wave sdk (like the windows zwave.dll) and would appreciate any feedback or feature wishes.
totallymaxed: maybe you can lend me a few Z-wave components to test the interface for some days?
