Hello,

possibly this might be a good solution:

sarnau/InsideViessmannVitosoft/blob/73e8e8c607ac31e14c646fd6861530cbcdd1ce7a/Viessmann2MQTT.py

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import sys
import time
import os
import serial
import binascii
import enum
from datetime import datetime
import struct
import paho.mqtt.client as mqtt
import logging
import logging.handlers

logging.getLogger().setLevel('DEBUG')
logging.info('Starting Viessmann2mqtt')

MQTT_USER = "mqtt username"
MQTT_PASSWORD = "mqtt password"

This file has been truncated. show original

There is a python script based on Viessmann Vitosoft configuration files for reading data points via Optolink and publishing them to an MQTT broker.
Unfortunately, I can’t try it out by myself, because my Viessmann Vitodens 222 WS2 communicates using the older GWG protocol, which is not supported by Vitosoft and thus not by Viessmann2MQTT.

Best, Berny
