KC868-M16v2 configure yaml for ESPhome

[athxp]

No, the card won't work below 50-60W. It gets dirty readings with disconnected sensors, even at 0.30A.
Can you send me an M20 card to replace the M16v2?

I received the N20 card, thank you.
It works very well. I'm using the CT sensors I got for the M16v2. However, I've already bought more "precise" ones.
