Rolled back HA one version, no change.
Restarted Proxmox host, no change.
Unplugged/replugged Zooz Zwave stick, no change.
This was all working normally when I went to bed last night.
Nodes vary from iblinds to door locks - but not all iblinds or all door locks. Hit/miss. Recycled the door lock and it goes green only to go red/dead less than a minute later.
