OpenV_NodeMCU

work based on Schnup89/OpenV_NodeMCU

files and changes for Viessmann Vitodens 200-W, with one heating circuit:

1. add text of extract_configuration.yaml to your configuration.yaml of homeassistant
2. add text of extract_automations.yaml to your automations.yaml of homeassistant
3. add text of Lovelace.txt to your LovelaceUI (rawconfig)
4. use the arduino sketch VitoWiFi_NodeMCU.ino (change your WiFi and mqtt settings)
5. the result in homeassistant should look like Lovelace.png

I used the Optolink adapter here: saidlm/Viessmann-optical-interface
