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've been quite happy with my Emporia monitor; it has its own app (which is actually half-decent) and wifi and talk-to-their-servers shit but it goes into Home Assistant quite readily and with a bit of faff you can ESPHome it and cut out the Emporia servers entirely (caveat, haven't done this myself but reasonably sure it is possible). CTs are quite chonk, the mains doubly so. Refreshes VERY quickly, often fast enough to catch spikes when motors turn on. Dunno if it's gonna work with your number of circuits but hey, it's a data point.
@ifixcoinops I've gotten several recommendations for them, went ahead and ebay'd a Vue 3 to esphome and install in one panel, and will get a couple more if it works out.
@emily good luck tracking down the culprit! How much leccydrinking we talking here anyway? Is it like a Sudden Lots? Got me curious now

oh wait what just realized PSE bills every *two* months, which means we're only using More Than I'd Like, not Holy Shit Something Is Very Wrong Here amounts (2280 KWh over two months, not 2280 KWh per month) I can still get into electricity usage optimization but at least it's only half ...
