My heating is demand based and my ventilation is measurement based. There is no real need for smart there past a set point and some hysteresis. An analogue comparator is enough tech there! The moment you make it clever past this you incur the overheads of the whole system production in the efficiency cycle. That means the manufacture and distribution of a complex computer system.
