Problem solved.
To change the I2C address of a Kmeter one need to write to register 0x08 the new address (one byte) and to register 0x09 the same address but with the bits converted (1 is 0 , 0 is 1).
After writing cycle the power.
Thanks to M5 technical help team.

Hello.
I am trying to use a M5core with LAN module to make a modbus TCP slave.
I tried a few Arduino samples but nothing works.
Can somebody help ?

Thanks

Hi.
As I understand from your site You are pointing to the industrial IOT world .
I am using the M5Stack cores, modules and sensors for industrial machines and have sometimes a problem to install them physically because the mounting holes is for Lego (not very industrial grade) and not for normal bolts.
Also in some sensors there isn't any flat bottom that can be attached to a surface .
Maybe is time to decide if you are industrial or hobby oriented .
