Periodic power consumption spikes on Proxmox VE 9.1.6 (Dell OptiPlex 7050) – normal behavior?

[andyB2018]

I agree that a smart plug can not tell the full story. I said 3.5W - 5W max on "idle" - without the spikes in the graphs above. Those are the values I generally see in HA (3-5W during "calm" periods).

Yes, case closed.
Thank you all for your time and effort!
