I have a new Raspberry Pi 3 mit the module RaZberry 2 Z-Wave.
The Openhabian works fine.
Then I installed the Razberry with
wget -q -O - http://razberry.z-wave.me/install | sudo bash
Then I call http://find.zwave.me and I see my Raspberry IP (192.168.178.199), then I click ti it (:8083) but he can’t connect to the z-wave module.
If the link jswim788 provided does not work may try:
sudo openhabian-config
then look thru all the options, should find one that will fix permissions, if that’s the issue.
