Control4 Energy Management System Longmont offers web based interfaces that make it possible to set up rules for your home’s energy use. You can specify in the beginning that you do not want to pay over a certain amount as a cut off limit at an hourly rate. What may happen in this scenario in a worse situation is that the interface will not allow you to use your washing machine maybe or toggle off the power to your refrigerator. You may want to specify that you only want to complete certain energy exhaustive actions like charging your plug-in vehicle, ironing or making ice in the deep freeze during off peak hours when energy is at its cheapest.
