Z-wave on C-7 breaks but comes online after shutdown

My Z-wave on my C-7 suddenly stops working after some time online. If I shut down the hub and turn it on again it works fine. But it then drops connection to all z-wave devices after a while...

After a shutdown and startup I have connection to ALL devices, but when I run a Z-wave repairit sais the nodes that worked after the restart are unreachable and the devices no longer work.

The z-wave firmware is up to date.

The Z-wave logs shows the following:

Any ideas?

Hi Henrik, Looks like you have some devices with a weak signal(the last 3 listed). You can try running a z-wave repair.
Please list your z-wave device brand/type and I'm sure some folks will jump in to help.

I noticed my z-wave is a little unstable at times, although it can be stable for a full week, but joining new devices can be hard to join and seem to create issues after. I've been joining devices slowly over a month to fully move over from my C4 to my C7

I solved it by deleting/excluding some z-wave devices that was not in use :slight_smile:
