I have been having so many problems with adding Zwave devices and not much luck, only a couple devices I have been able to add. I was going to try the openzwave beta, but I decided not to. I had added the integration but removed it not long after. Things were working fine after I removed the integration but I just added a networkkey in options file, rebooted and now having this issue, trying removing network key and rebooting and still having this issue.
