You can figure out your electrical expenses by the hour, day, week, month and even an entire year. After using the devices of Control4 EMS 100, you will be appalled to find out how much money you have been spending by simply ignoring certain appliances and leaving them plugged all day long. You can even assess how much that twenty year old refrigerator in the kitchen is costing you each year. You can take a broader look at your house’s energy use. Use Control4 Energy Management System Rapid City with devices that monitor your whole home energy use. Some products plug into an outlet and combine your home energy consumption rate with information about your local utility costs, time of day and the climate to report to you if you are using too much energy.
