A weird thing occurred this evening while I was out of the house. I got a bunch of notifications on my UD Mobile app that nodeservers were going offline. Various systems stopped working that depended on the nodeservers. I got home and went to the admin console and noticed that all my programs had disappeared. The top level node was empty. I restored from a backup but the ZWave devices are missing. When I click and do a Query on a ZWav devices I get an error dialog "TCP client read response failed". Other devices just say "Request Failed"
I tried healing the ZWave network and rebooting and updating the system to the latest firmware, disabling and reenabling zwave support in IoX, rebooting and restarting the system, but the zwave functionality remains broken. Nothing in the zway.log jumped out at me. The failure has affected switches, thermostats, open/close sensors, pretty much everything.
When I reboot I get a long system busy dialog and then a bunch of zwave device not awake messages.
Would appreciate any suggestions on what to do here.
