Hi,<br>
<br>
The sections are separated by semicolons, and not all sections will appear in every status line (one that starts with ‘=‘).<br>

The target is currently 10C, the FROST target is 10C and the WARM target is 21C,<br>
the unit has a comfort bias, the prediction is that the room shouldn’t be heated for this hour and the next, and there is a strong indication of room occupancy.<br>
<br>
This is NOT properly externall documented yet.<br>
<br>
However, if you look in UI_Minimal.cpp at serialStatusReport(), much will be revealed.<br>
<br>
Martin is working on a more human-friendly front end on this rather minimal CLI/UI!<br>

I powered up another one but buttons, etc didn't seem to relay. presumably i need to sync them somehow. I'm all ears for suggestions. I will dig through the code if necessary but some pointers to relevant parts would be great.<br>
