I have just deployed it on my D325, it works really well! ❤️

Couple of questions:

• The comfort temperature setting does not seem to be mentioned in the docs. Any reason for this?
• A suggestion to also state explicitly in the docs that users need to also connect their ESP to one of the ground pins (of course being careful not to short USB and Duco ground). Without ground, UART will probably not work.
• Any clue what the BOX, UCBAT, SWITCH and UC nodes are (I only detect BOX and UCBAT myself)?
• Possibly related: I can see on the Duco display that it can measure indoor and outdoor temperatures. Can those sensors be read over UART as well?
