How Smart Thermostats Generate Real Financial ROI
According to EPA Energy Star figures, heating and cooling account for more than 50% of the average household energy expenditure. Smart thermostats employ geo-fencing (detecting when your smartphone leaves home) and occupancy sensors to drop temperature during vacant hours, returning to comfort moments before arrival.
