adjust the temperature up or down so energy isn't being wasted. * Additional features include remote room sensors and voice control. Before you buy, learn what you can about the functionality of the smart thermostat's app. And take a look at how easy it is to program the thermostat unit directly. Finally, consider the installation. Some models are more difficult to install and may require re-wiring. Smartphones and other devices make it easier than ever to take control of home energy use. Smart Power Plugs and Switches Smart outlets and light switches are still considered a relatively new technology, and we think improvements will be made over time. That said, if this is a technology you're interested in, there are a couple of options that consumers seem to like. Hub-based systems like the Currant Dual Smart Outlet and Philips Hue smart lighting systems are highly rated and cost about $200 or more for eight to 10 smart outlets or light switches. That's a pretty big investment, so we recommend using an energy-cost-calculator app first to decide if it's worth the additional cost. We hope these reviews will be helpful as you consider smart technology that promotes energy efficiency. Don't forget to check with your local electric cooperative on additional programs and services designed to help you save on your energy bills.
