I think I misunderstood what L1/L2/L3 are for. Are they to measure the voltage of each phase? -- Yes
Voltage and current work independently. If you want to test a load current of 200A, you need to replace the resistor, which is not related to voltage.

Hi
I can only measure up to 64A at ESPhome.
At input of 0,35Vrms
When I check the datasheet input is only 0.7Vpp.
Can you send me firmware for 200A and wich resistor value I need?
Thanks in advance
Linus

if want use for 200A CT sensor, every channel need replace 2pcs resistances, so 30 channel need replace 60pcs resistances, it's really cost time if you want do it.

Yes sure no problem easy doing in lab.
Can you send me the value

M30 PCB need replace these 60pcs of resistances with 2.49ohm, so that every input channel can use for 200A CT sensor.

Hi
thanks for the feedback.
Please send me then also the right firmware for it.

Hi,
current is now working well.
But the YAML has some failures.
M30_CT bl0910_1_voltage: 15.145.419,0V
Temp and frequence are Unknown
Which register they have?
Have you a list with all the register.
As I see the file is unsignet, that means it has no negative values for the power

can you test with KCS firmware. enable mqtt auto discovery, easy integrate to home assistant.
address:1100-1167 is the first chip-BL0910
address:1200-1267 is the second chip-BL0910
address:1300-1367 is the third chip-BL0910

ok changed the YAML acordently now working.
tps2 is still 0°C
Do you have a firmware for signed power?
