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.
A tplink smartplug (hs110), with a small node app, fetching the value to push it to influxdb
I splurged on an used APC metered PDU, which I then pull data from using telegraf which is stored in influx and displayed with grafana.
I use rpiPowerMon:
Oh awesome! I love finding additional uses for my pi’s.
My UPS systems have built in monitoring.
Emporia. Fairly reasonably priced for what you get. I have 2 units. Main panel 16 circuit and sub panel 8 circuit.
Because the only thing that matters at the end of the day is the overall total power consumption for my apartment I have an Emporia Vue sitting next to my breaker box graphing the data for all three phases. I spent a year logging values and then compared them to the bill (and monthly consumption numbers) sent out by my energy provider to know how those measurements relate to the actual billed amount since those sensors are never 100% accurate.
Did it help?
Look up “TAPO P-100” It’s an IoT plug you can connect up with an app and it tracks your metrics as well as breaks up monthly cost once you throw costings at it
Tuya Smartlife Zigbee Energy Meter. 20$ for single sensor, there’s also a version with 3 sensors for slightly more.
Data goes in HomeAssistant for quick monitoring and InfluxDB for further checks.
I compared it with readings of the energy company meter and it was within a 5% error over 6 months.
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/
overall entire house: IoTaWatt. with this I monitor the power usage on every individual breaker in my house plus the 240VAC mains
for the home lab: combination of my APC network management card V3 in my UPS, which shows aggregate lab power usage but i also have a cyberpower pdu81003 that gives me outlet level on/off controls and outlet level power monitoring.
all of these report back to my InfluxDB database and i have nice grafana dashboards.

Wow. Thorough. I like it! 👍
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
IOTAWATT
I have a Shelly Plug since a few weeks now, it’s great
Kill-watt-meter
TP-link wifi plugs with energy monitoring (theres a 4pack on sale right now too) and theres a github repo for a energy monitoring docker and also one for grafana that pulls from these tp-link smart plugs.
