Using the KW protocol I get:

Seems to work apart from the fact that -0.1 is totally wrong, it should be about 5.98 degrees.
If I use protocol 300 I get:
setup finished...

(after 10 minutes or so...)

It reads fine once. There is no activity on the TX pin on consecutive read attempts.
And it is not displaying its interpretation of the received data.
I modified your readDatapoint sketch. I commented out the boilertemp datapoint and addded
// setup VitoWifi using a global callback handler
VitoWifi.enableLogger();
VitoWifi.setLogger(&Serial1);
