I use temperature and humidity sensors to control my HVAC via indoor dew-point rather than temperature alone.
This has really raised indoor comfort and saved money, because a particular dewpoint can be reached by either decreasing humidity or decreasing temperature. With a two-stage heat-pump, during cooling, running in Stage 1 costs less money and primarily dehumidifies. Whereas running in Stage 2 costs more and cools rapidly. Using a Hubitat-controlled thermostat that permits staging, my automations determine whether it would be desirable to reduce humidity (the major choice in Away mode) or reduce temperature (the major choice in Sleep mode) to achieve the desired dewpoint. In Home mode, it starts out in Stage 1. If the desired dewpoint isn't reached within 20 minutes, it shifts to Stage 2.
