Sense power consumption API

Is there an API that smart devices can use to report power consumption to Sense? I have several energy hogs such as a dehumidifier and driveway heaters that sense doesn’t recognize, and that are wired directly into breakers. So I can’t use a smart plug. What I’m thinking is I could build a device using a raspberry pi and a current clamp that would report energy usage to sense, like a Wemo smart plug does. Or has someone done this already?

Some discussion of that here.

Nothing ready-built. The best route would be to develop arduino software that emulates the few commands of the TP-Link protocol that Kasa setup and Sense need, while continuously querying or calculating device power of your wired AC device.
