counter img from: https://eu.landisgyr.com/blog/european-utility-week-2016/advanced-metering-infrastructure/e360

Counter has P1 port for read parameters by DSMR protocol

UART FTDI Adapter for connect to P1 port

I buy adapler on aliexpress

adapter

Software

Library

I use https://github.com/ndokter/dsmr_parser library for read values and use example from README

Example

from dsmr_parser import telegram_specifications
from dsmr_parser.clients import SerialReader, SERIAL_SETTINGS_V5

serial_reader = SerialReader(
    device='/dev/ttyUSB0',
    serial_settings=SERIAL_SETTINGS_V5,
    telegram_specification=telegram_specifications.V5
)

for telegram in serial_reader.read():
    print(telegram)  # see 'Telegram object' docs below

run it and get log in telegram format

You can get single values or units: 

# Print contents of all available values
# See dsmr_parser.obis_name_mapping for all readable telegram values.
# The available values differ per DSMR version and meter.
print(telegram)
# P1_MESSAGE_HEADER:                42 [None]
# P1_MESSAGE_TIMESTAMP:         2016-11-13 19:57:57+00:00 [None]
# EQUIPMENT_IDENTIFIER:         3960221976967177082151037881335713 [None]
# ELECTRICITY_USED_TARIFF_1:    1581.123 [kWh]
# etc.

# Example to get current electricity usage
print(telegram.CURRENT_ELECTRICITY_USAGE)  # <dsmr_parser.objects.CosemObject at 0x7f5e98ae5ac8>
print(telegram.CURRENT_ELECTRICITY_USAGE.value)  # Decimal('2.027')
print(telegram.CURRENT_ELECTRICITY_USAGE.unit)  # 'kW'

# All Mbus device readings like gas meters and water meters can be retrieved as follows. This
# returns a list of MbusDevice objects:
mbus_devices = telegram.MBUS_DEVICES

# A specific MbusDevice based on the channel it's connected to, can be retrieved as follows:
mbus_device = telegram.get_mbus_device_by_channel(1)
print(mbus_device.MBUS_DEVICE_TYPE.value)  # 3
print(mbus_device.MBUS_EQUIPMENT_IDENTIFIER.value)  # '4730303339303031393336393930363139'
print(mbus_device.MBUS_METER_READING.value)  # Decimal('246.138')
print(mbus_device.MBUS_METER_READING.unit)  # m3

# DEPRECATED: the dictionary approach of getting the values by key or `.items()' or '.get() is deprecated
telegram[obis_references.CURRENT_ELECTRICITY_USAGE]
