RE: M30 configure yaml for ESPhome - manubenoit - 09-23-2024
Hello,
I just installed a M30 with a couple of CT clamp from NJXS for 400A/1V and 200A/1V.
I've installed the yaml file (copy/paste) from forum and it works! I'm not sure that the readings of amps are OK. I assume we have to tell the yaml code that it's a 400A/1V or 200A/1V so the readings are accurate..
I would assume for lighting purposes, we would have to change the "substitutions" at the beginning of the yaml file for the exact amps fuse of the circuit (even if different than the CT clamp amp rating).
I would assume that the multiplier would be where we can adapt with the actual CT clamp amps rating. Is it possible to help me out with the calculation of the multiplier if need be. I'm using only 1V CT Clamp with different amps rating. (400A, 200A, 30A, etc. to 1V)

where the CT sensor you buy from? our yaml file use CT sensor 2000:1 version. if your CT sensor not use by 2000:1, you can modify your yaml. just need to calibrate data.

Here is the link where I bought it on AliExpress. I asked the seller what was the ratio and waiting for the answer.
Just found this amazing item on AliExpress. Check it out! C$11.18 | NJXS OPCT35AGL Split Core Current Transformer 1V Output with 3.5mm Audio Jack AC CT Clamp Sensor 100A 200A 300A 400A 500A 600A

Thanks for your help.

using this yaml, esphome logger gives this warning:
[W][modbus:114]: Modbus CRC Check failed! C071!=00
RE: M30 configure yaml for ESPhome - admin - 10-29-2024
Ignore this log warning.

Hi, I've applied those yaml, and without connected any clamp whole phase 2 shows power consumption:
https://share.merce.com/files/7d663551-8955-4783-a2eb-d1b0b04c69a8.png
Can I adjust it anyhow withlout setting hard offset? I changed decimal to 2 but instead of showing 0,009 it makes 0,01 what is understandable.
Any other hint?
Regards

it's normal, just connect with your CT sensor have a test.

Good morning, the m30 board reads me a power value of 150w less. I noticed that the more it increases the power, the greater the difference in reading. Can the incorrect reading be calibrated?
RE: M30 configure yaml for ESPhome - admin - 04-11-2025
power value is manager by BL0910 energy iot chip. maybe your load power factor is not 1
RE: M30 configure yaml for ESPhome - davidemarino33@gmail.com - 04-11-2025
admin how do i see the power factor and change it?
