My problems are a) I need temperature sensors in at least 4 different spaces to get it right, 2) the central heating system / boiler only talks some proprietary RS-232 stuff (I assume there are no real, accepted standards), and 3) temperature adjustment needs to take into account wind strength and direction, as the north/south ends of the house let wind straight through, while east/west side walls are solid double-layer brick...
