Either all home electricity with data being gathered near/at meter, or targeting a specific point, like your home-lab consumption or particular devices?
I’m just looking for helpful tools to help visualize and monitor energy consumption.
I personally use a combination of…
Per Circuit Monitoring: https://static.xtremeownage.com/blog/2023/home-solar-project-part-3-monitoring/
Sonoff S31s for individual devices: https://static.xtremeownage.com/blog/2023/sonoff-s31-low-cost-energy-monitoring/
A few HS300 Power Strips: https://static.xtremeownage.com/blog/2022/kasa-powerstrip-as-pdu/
Several locations.
- bunch of metering smart plugs flashed with Tasmota, feeding into Home Assistant (power at the wall)
- UPS being polled by LibreNMS (difference in load Vs wall shows the UPS consumption)
- metering PDU polled by LibreNMS shows the server load
- PMBus PSUs in the servers report their own power consumption to the BMC
And after all this, I do… Nothing with this data.
I just use a Tapo Smart Plug, don’t know how accurate it is but it gives me an idea, my unRAID server runs idle at about 70w (with relevant drives spun down) not the greatest I know, in the iOS app you can input your local cost per unit and it will give you an estimate on daily/weekly/monthly running cost
smart plugs for devices and shelly CT clamps for home/circuits. all integrated into home assistant.
The Bill at the end of the year.
