HA - modbus SDM 630

Hardware
1

Good day
I use energy meter SDM630, USB serial.
These settings work
core-2021.6.6
the version is no longer functional.
core-2021.7.3

In the configuration.yaml file I’ve the following:

modbus:
type: serial
method: rtu
port: /dev/ttyUSB0
baudrate: 9600
stopbits: 1
bytesize: 8
parity: N

2

according to that instruction, it was operational for half a year

3

This will probably be the answer to my question.
But I’m quite an amateur and I don’t know what to change. Can anyone advise?
Thank you

ill try to help as i just converted mine over. Do you currently have all of your sensors in the sensor.yaml?

modbus:
  type: serial
  method: rtu
  port: /dev/ttyUSB0
  baudrate: 9600
  stopbits: 1
  bytesize: 8
  parity: N


# Sensors
sensor:
  - platform: modbus
    registers: !include sdm630_registers.yaml

I have in my own file

im not an expert on splitting through files like that im sorry. I basically have nothing in sensor.yaml anymore related to modbus. I moved everything into the config.yaml. this is my working config now for the modbus. you put the sensors right below the modbus: entry.

configuration check:

Invalid config for [modbus]: [register] is an invalid option for [modbus]. Check: modbus->modbus->0->sensors->0->register. (See /config/configuration.yaml, line 19).

they dont use the word register anymore. change register: 2 to address: 2

and register_type is now input_type
