What is the best smart thermostat for energy savings?

The Nest Learning Thermostat and ecobee Smart Thermostat Premium are the top choices for energy savings. The Nest learns your schedule and creates an optimized heating and cooling plan, earning top Energy Star ratings. The ecobee includes room sensors that detect occupancy and temperature, adjusting based on which rooms are actually in use. Both save 10 to 15 percent on heating and cooling costs on average. Check with your utility company for rebates that can significantly reduce the purchase price. Both integrate with major smart home platforms.
