Something in my house is sucking a *lot* of energy and I would like to find it and make it stop doing that. Anyone have specific recommendations for multi-circuit power-usage-tracking devices? (I have 13 240V and 18 120V circuits across three panels, suggesting I will probably need three such devices; the most populated panel has 10 120V and 2 240V.)

Other requirements: ideally #homeassistant compatible, not internet based (currently have devices on zwave and non-internet-facing wifi, adding zigbee soon for unrelated reasons), works with normal US split phase power. Assume I am a reasonably competent electrician and am comfortable putting a current transformer around a wire.

@emily I highly recommend https://www.egauge.net/

Handles a mix of 120/240V circuits (30 120V or 15 240V or a mix of those; you can even set up logic for a single CT on a 240V load if you don't mind a loss of accuracy). Integrated data logger and webserver, no cloud nonsense required. Data output via Modbus TCP/RTU, CSV, and I think the JSON API is available now too. Second-granular data for the most recent ten minutes; minute-granular for a year after that, 15-min for 30yr after that.

You can even import data from Modbus TCP/RTU devices, or from one meter into another meter.

I have one on my house and one on my garage/apartment. You can see the data here if you'd like: https://celestial-bastion.egaug.es/

I also have a bunch of environmental sensors and other measurements (THD, L1-L2 voltage imbalance, line frequency) but you have to click the dropdown in the top left corner of the graph to see that data.

Full disclosure, I also worked for them from about 2013 to 2022.

@emily I should clarify that they don't have cloud functionality (all data is stored on the meter), but the company offers a proxy service so you can access your meter remotely without port forwarding. If you use that service they do collect firmware version and a few other details, but you can opt out of that entirely by just disabling the proxy connection in the meter UI.

They pretty much require an NTP server (unless the design has changed, they lose date/time on extended power outages) so either point it at an internal server or allow it outbound access to an external server.

I also don't know where they're at with HA compatibility, sorry. Forgot that was one of the criteria!

@notthatdelta honestly, if shit just follows documented standards I am happy to bodge together a whatever-to-mqtt bridge if I need to
