@gatewayy I've got a Home Assistant setup. Bought some Kasa brand smart switches that have power consumption built in; and this integrates into Home Assistant ... pulls in the current consumption rate, plus builds a historical graph.
(I'll use this to build out the annual cost to build the business case to my budget manager (aka "wife") that I need to get rid of that machine and get myself a high-end miniPC with a few terrabytes of storage on which I will build an array using UnRaid.
It takes data to do this.
