As the concept of home energy management systems has evolved so too has the technology that enables its capacity. In the rapidly evolving market of smart home technology there exists a place for homeowners, occupants, utilities and energy managers to tap into the potential for real time control and feedback that has never existed. With the evolution of the internet of things the smart home has also come into existence and into reach for many homes.
