Got an emonTx v3.x with 3x CTs connected.
Calibrated the numbers under some load and am getting readings in the ballpark of my smart meter.
However, there is no current and even when I remove the CT from a cable, the emonTx is still registering between 2 and 4W.
Is that normal? - is that down to calibration? - is there anything I can do about it?
It’s annoying now i’ve moved the clamps to my solar generation instead of grid feed, so it looks like i’m generating a few watts over night, when in fact it’s not.
