RE: M30 configure yaml for ESPhome - pawelb - 05-12-2025
Deamn its compleatly useless... with KCS there are the same values. Shelly shows 640 over load but M30 shows 284.90W at idle its 100W more than it should. Seams that I paid many $$ for useless hardware... ;( Any other idea how to work this out?
RE: M30 configure yaml for ESPhome - pawelb - 05-13-2025
ok, My other question is mayby my ct clapm wrong?
Bought those:
https://pl.aliexpress.com/item/32231711500.html?spm=a2g0o.order_list.order_list_main.56.7bd91c248qDQvs&gatewayAdapt=glo2pol, but seams to be correct 20A/1v...

make sure CT sensor is 2000:1
RE: M30 configure yaml for ESPhome - pawelb - 05-13-2025
Product card says: Strength: 6000VAC/1min. This is param taht you are writing about?
RE: M30 configure yaml for ESPhome - admin - 05-13-2025
Coil turns ratio, Just like the turns ratio of a transformer, you can ask the CT sensor's supplier.
RE: M30 configure yaml for ESPhome - pawelb - 05-14-2025
I'll do that, but is it normal that my clamps overstate the real consumption at low loads and significantly understate it at high loads? I'm trying to achieve consistent readings, and I'm unsure if I need to replace the clamps. If so, which ones should I use? Alternatively, is there any way to correct this through software adjustments?
RE: M30 configure yaml for ESPhome - admin - 05-14-2025
you can try to by this way:
filters:
- calibrate_linear:
# Measured value of 0 maps to 0A
- 0 -> 0
# Known load: 4.0A
# Value shown in logs: 0.1333A
- 0.1333 -> 4.0
here is details: https://esphome.io/components/sensor/ct_clamp.html

I would like to buy one clamp to exclude bad readings of consumption on the current clamp. Could you recommend a specific model, amperage?

these CT sensor all support KinCony energy meter board directly.

Are these buckles your production or can I buy them somewhere else? Because the shipping will kill me from the official Kincona website ;(
