What sensors/ software do you use to measure energy consumption? (alien.top)

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 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

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.

:) But you have a system in place should you need it. And I say All Data can be useful if filtered correctly.

I have a esp32 gizmo connected to my meter. It has a built in web server displaying live data, and also pushing MQTT data to Home Assistant.
