Prior Art Today, the limitation of energy resources and the continuous increase in energy need, has necessitated a more controlled and economical use of energy. This necessity of electricity, which is one of the most used energy types in the world. It also encouraged steps to be taken to use it more sparingly. This In this context, the issue of smart grids has come to the fore and electrical networks are doubled. Equipped with directional communication, more controlled and more efficient energy consumption Significant work has begun on its realization. In this issue academic studies, energy management in buildings, serious energy shows that savings can be made. Considered within the smart building structure In home control systems, monitoring and control of energy consumption has an important place. started to hold. For this reason, the energy consumption of household electrical appliances monitoring and controlling both reflects positively on the consumer's bill, and Thus, the savings achieved contribute to the environment and economy.

The desire to control and monitor the electrical devices in the houses is the new so called smart socket. The concept led to the emergence of sockets.
