M30 configure yaml for ESPhome

[pawelb]

OK, I bought a CT clamp exactly like the 30A one you have in your store. I have this clamp, an old one, and a Shelly meter on the same circuit. Each of them shows different readings. Under load: Shelly shows 528W, YHDC shows 357W, and the other one shows 317W. Without significant load: Shelly shows 188W, YHDC shows 231W, and the other one shows 207W.

Is it possible to configure this so that the readings are accurate? Supposedly, the current transformer I bought for testing doesn’t require calibration, but it still shows absurd values… ;(

Or maybe my m30 is broken??
