zwave plugs in a couple of places (servers, media center) and zwave CT meter at the panel for the whole house. Metrics pipe to home assistant, then prometheus scrapes home assistant and grafana displays the data.

edit: also listen in on the electric company's (and gas and water) broadcast with rtlamr2mqtt

looks like a steady 330, single storage host 7 spinning disks, 4 SSDs, 4 rpi-4 with SSDs running k3s and the network stack (edgerouter 8-xg, 2 8 port poe switches and a 24 port es-24).

Changes I should make are to reduce drives / upgrade storage host in a couple of years and switch out to a single, larger poe switch (2.5G 24-48 ports), again in a couple of years.

I use a POE hat and I think they have options for power it, even beyond that you could get a dremmel out and start making more ports. The ports being on top would make any case that doesn't take that in mind just about impossible to use. I'd look at a shelf or modifying another enclosure.

The uctronics stuff won't work? I use that with poe powered PIs and it works great.
