Hi,
I got the long standing issue where cloud backup results in a totally frozen zwave controller. IMO this should be the number one issue to get fixed. I got the cloud backup a couple of months ago to add reliability, not to cause issues. It is running weekly at 3 AM.
The only thing that was different from prior weeks that I was running a device OTA and for some reason it takes 20 hours on the Shelly Wave Plug S (same slowness on a Model 7 which I use for development, but a Shelly Wave 1PM updated in an hour go figure!?!)
C8 Hub EU latest firmware 2.4.3.137 (before you ask; ZIP, no JS), 55 zwave devices
If it can be useful, support can send me a PM for my Hub ID to look at the engineering logs.
Cheers Rene
Haven't seen a disabled ZWave radio lately from this. Have occassionally gotten the warning message that says the cloud backup wasn't successful and failed on the ZWave portion - doing a manual cloud backup is all that it takes at that point to make the message go away.
Hi @thebearmay ,
I do have the zwave error message when I opened the Settings -> Backup/Restore and I had to do a power down on the Hub to get z-wave responding again. The power cycle did not clear the error message. At the moment I am deliberately not redoing the backup in the case support want to have a peek.
Cheers Rene
I have 1-2 / z-wave devices that refuse to work after a failed backup.
And sometimes after a reboot also 
I have not figured out how or why yet.
Nor can I tell you what works to get them working again.
Most times just screwing around with different settings/drivers/on-off stuff.
