Since the last few days I have been seeing all (only six) my ESPHome devices regularly lose their network connection for just a few seconds before they come back. At least I can say that the sensors become unavailable in HA.
The thing that has changed is that I migrated from Ubuntu/HA to a HA on a Proxmox VM (using the same NUC) and because I think it might be important to know, my UniFi controller is the HA add-on so the same IP address as my HA instance.
But what is really weird is that following the complete rebuild of the NUC the hostname still appears to be ‘Ubuntu’.
My Proxmox node is 'Proxmox’
My hostname in the Proxmox console is 'Proxmox’
But tracert shows it as 'ubuntu’
As does my quick and dirty network scanner
Strangely, UniFi controller shows it as having no IP address or hostname
Tomorrow I plan to reset all my Unifi network, rebuild the Proxmox NUC and start everything from scratch.
Unless of course before then someone here can offer some hints as to what on earth is going on.
Please?
