I have been having a lot of issues with the Z-Wave on my C8 Hub.
First, I always update the C8 whenever there is a new version available. Currently it is running version 2.3.9.135.
Over the past few weeks, I have had the cloud back-up fail four times now. It is always that it cannot back-up Z-Wave settings. When this occurs, Z-Wave is no longer working on the hub meaning I cannot control any Z-Wave devices but the Zigbee and Matter devices continue to work as expected.
Unplugging and restarting the C8 does nothing. The only way to get it working again is to restore one of the last good back-ups.
I never had this issue with the C7, only the C8 and only very recently. Seems the Z-Wave portion of the hub might be failing.
I have Hub Protect. Any suggestions as to hardware failure of otherwise?
