Z-Wave repair routine doesn't work, and neither do any z-wave devices

Sometimes one bad device can flood the network with messages, and that can prevent the zwave repair from completing. So I agree, it’s worth checking the logs if you feel like going to that effort.

You probably know all this, but just in case, here’s the logs FAQ:

The following probably doesn’t have anything to do with your issue, but I just want to mention it in case someone finds this thread later, which is that there is a known problem if you have more than one Sonos devices attached to your network where they flood the system and zwave messages can’t get through. ( from an engineering standpoint, that doesn’t make any sense, but apparently it does happen. ) The only workaround for now is to remove Sonos devices and then magically Z wave devices all start working again.
