Viessmann via USB-CAN adapter

Are some of our developers here aware of open3e project where you can access viessmann heater via USB CAN-Bus adapter and MQTT? Not sure if this is already known here otherwise forget my post.
I found this project in this thread where you can get some more information (german language).

Link to USB CAN adapter for 35€

There were some attempts of CAN integration through serial binding and line based protocols. I haven’t looked at protocol used by viessman, but in practice its all about making sense out of 11 bit can object id and 8 bytes of data.
