In recent decades, there has been an increase in the use of robotics in home automation environments. That, joined to the interest in efficient consumption of energy, is the base of the research exposed next. Nowadays, the increase of robotic systems in human daily activities has facilitated its integration and diversification and, due to this, new needs have come up. An example of this situation is the case of service robots that, as well as give comfort to the user, they can provide an energy efficient consumption. The aim of this work is to lay the concept of energy and Smart Grids in a smart home interoperability protocol like DHCompliant. This will make possible a greater energy and economic saving, providing the user the possibility of making strategic decisions regarding their energy consumption.
