Not 0 when mo power !

[vincegre]

Hi

Just bought the complete kit and I'm quite impressed by quality of the board and design but I have an annoying issue. Even without CT connected or CT connected but laying on table, ESPHome reports some small consumptions on each input ! I have around 100W measured while it should be 0.
I'm using your default code as you supply. How to fix the problem ?

Thanks

Hi Vincèn,

Thanks for supporting the project! It can be that you may need to play around the calibration coefficients associated to each CT clamp. @lucazeta1975 opened some days ago a nice discussion with some updated calibration factors, I'd recommend them to give them a try or check out the calibration procedure from the docs 😉😉.

Let me know if this helps.

PS: I'm converting this issue to a discussion as it fits better.

Hi @JGAguado

Thanks a lot for your answer and for moving it as a discussion ;)

For calibrations I have done it once installed in electrical panel and discussion of @lucazeta1975 confirms what I have done too.

My only issue now is that once packed in electrical panel to be able to close it I have some small consmuptions measured that should not be there. Is it i a problem if CT are side by side or very near of each other ?

Best
