Thermostats

Smart thermostats make it easier to use less energy and save money because of their advanced features, but you have to take advantage of those features in order to see a benefit. Options like automatic home/away modes based on your phone's location -- or sensors in the thermostat and in remote accessories that detect proximity -- can go a long way toward reducing your monthly bill. In addition, if you take the time to review the energy usage reports smart thermostat companies provide, you'll be able to identify patterns and potentially save even more money.
