This is missing:

## ---------------------------------------------------
# Serial interface uart 
# board: "az-delivery-devkit-v4"
## ---------------------------------------------------
uart:
  id: my_uart
  tx_pin: GPIO17 # orange
  rx_pin: GPIO16 # white
  baud_rate: 300
  data_bits: 7
  parity: EVEN
  stop_bits: 1

obis_d0:
  - id: my_sm
    uart_id: my_uart


## ---------------------------------------------------
# the device need to be triggered to sending data. 
# We can use the integrated "interval" component 
# send the command: 2F3F210D0A ('/?!\r\n')
# see: https://github.com/jplitza/esphome_components  
## ---------------------------------------------------
interval:
  - interval: 60sec
    then:
      - logger.log: "Init reading data for ${device_name_short}"
      - uart.write:
          id: my_uart
          data: [0x2F, 0x3F, 0x21, 0x0D, 0x0A]

mt174

Protokoll is:

# ---------------------------------------------------
# Testcase protocoll for ISk5MT174
#  MT174-D1A52-G22-M3K0
# ---------------------------------------------------
# serial port read data d2 protocoll for ISk5MT174
# /ISk5MT174-0001               Start Telegram / and Device Name
# 0.9.1(130203)                 Current time (hh:mm:ss)
# 0.9.2(0230223)                Date (1YY.MM.DD)
# 0.0.0(00339188)               *Device address 1
# 0.2.0(1.03)                   *Firmware version
# C.1.6(FDF5)                   *Firmware check sum
# 1.8.1(0011404.409*kWh)        Positive active energy (A+) in tariff NT [kWh]
# 1.8.2(0023813.725*kWh)        Positive active energy (A+) in tariff HT [kWh]
# 2.8.1(0015608.962*kWh)        Negative active energy (A-) in tariff T1 [kWh]
# 2.8.2(0000900.569*kWh)        Negative active energy (A-) in tariff T2 [kWh]
# F.F.0(0000000)
# !                             End of telegram

What i am missing:

  • decode Devicename as textsensor
  • Event End of telegram to execute a script.

Simple python script to get the data from a weidman IR Schreib/Lesekopf USB (Optokopf):

#!/usr/bin/env python3
import serial
import time

## ls -l /dev/serial/{by-path,by-id}/*
## lrwxrwxrwx 1 root root 13 Jul  2 13:33 /dev/serial/by-id/usb-FTDI_FT230X_Basic_UART_D307N80T-if00-port0 -> ../../ttyUSB0
## lrwxrwxrwx 1 root root 13 Jul  2 13:33 /dev/serial/by-path/pci-0000:00:14.0-usb-0:5:1.0-port0 -> ../../ttyUSB0

## dmesg | grep tty
## [534356.058130] usb 2-5: FTDI USB Serial Device converter now attached to ttyUSB0
SERIALPORT = "/dev/ttyUSB0"
BAUDRATE = 300
ser = serial.Serial(SERIALPORT, BAUDRATE, serial.SEVENBITS, serial.PARITY_EVEN)
ser.write(b"\x2F\x3F\x21\x0D\x0A")
time.sleep(0.5)
numberOfLine = 0
while True:
  response = ser.readline()
  print(response)
  numberOfLine = numberOfLine + 1
  if (numberOfLine >= 11):
     break
ser.close()
