… back agein with a new project 
My garden irrigation system has been running for a few years now.
I would like to integrate my Vitocal 200 G heat pump with Vitronic 200 WO1C / CU401B_G control into my openHAB system.
The Pi ↔ heat pump connection works well via Optolink / vconnectd.
My current problem: the heat pump ports are not really documented and it is tedious to figure them out in order to create the parameter file for vconnectd. Does anyone know anyone who has something like this working? Perhaps someone can help here with know-how transfer 
Thanks in advantage
Ulli.
