Can anyone point to resources, reviews or experiences on monitoring power usage in 240v ac (US)?

Looking at the new energy dashboard features …. I have opower integration of my electricity usage and a nice graph. However most of my power usage is from a heat pump, and EV charger, and maybe a garage heater. All are 240v, larger current loads. So the new feature is something about graphing device usage with overall usage. So that would be cool to add

I started searching online and it doesn’t seem especially positive. I see a few clamp meters with integrations but also see reviews that they’re not very accurate.

    That’s an interesting idea - is there a guide for newbies? I’ve never done anything with esphome.

    I had been expecting to use the total power from my utility but perhaps that’s a better idea: measure total power with the same tool as individual.

    Right, a big part of the goal is to identify whether untracked is significant.
