Everything was working fine until yesterday, today morning nothing worked though.
This is what I've done so far:
I disabled the Z-Wave network, waited 15 secs and then enabled it again, my Z-Wave network disappeared.
I panicked and did a hard reset (unplug power cable) to reboot the Z-Wave stick (EU version), waited 30secs and power on again, still no Z-Wave network.
I restored from a backup from a couple of days ago, still no Z-Wave network.
I shutdown the hub from the menu, waited 15 minutes and power on again, the Z-Wave appeared, but nothing worked.
I'm currently running a Z-Wave network repaired, it's been running for 45 minutes so far, through 5 nodes. None of them are working. I have 30+ devices, so at this speed the full repair should take about 5-6 hours, when the system worked it lasted between 4-7minutes.
So what I do now? I hope I don't have to include again every device...
There’s a hotfix (.158) out for something that sounds similar (Release 2.2.4 Available), but only mentions the C7 so not sure. I have seen a few people reporting similar issues today though. Copying @email@example.com to get a more official viewpoint.
IMHO I don’t think the repair is going to resolve your issue, but it isn’t going to break anything either. So your call on continuing.
I’ve seen a couple of people were reverting back to a previous verion of the firmware and then restoring a backup made under that version. Not sure I’d do that before someone from support chimes in, but might check to see what versions you have backups for in case they ask,
Fortunately or unfortunately, depending on how you want to look at the problem, nothing has changed in the Z-Wave firmware for C5/C4 hubs. This sounds like the USB stick may be failing or may be simply disconnected (it happens often). Have you tried unplugging and plugging the USB?
For what it's worth, I also had my first z-wave failure yesterday morning, but I only lost 1 single device and it was recovered with a repair. I am on C4 with 22.214.171.124.
I also had an issue a few weeks back where the hub became unresponsive, but then recovered.
This then leads me to what @bobbyD is saying above. Could it be that hubs slowly deteriorate over time ? Can it for example be ralated to NAND flash write times ? This would then be similar to what has been happening to some Tesla drive computers where the flash has reached it's re-write capacity.
