Smart switch and smart home system using the same

A smart home system comprising at least one smart switch and a gateway communicating to the smart switch with each other via Power Line Communication (PLC) or Optical Fiber Power Line Communication (OPLC), the smart switch connecting to a power and at least one electronic device, the smart switch comprising:

• a screen;
• a power detecting unit configured to detect real-time electricity information of the electronic device connected on the smart switch;
• a processor unit connected to screen and the power detecting unit, comprising a calculating module configured to calculate total electricity consumption of the electronic device according to the real-time electricity information, and a control module configured to control the screen to display the real-time electricity information and the total electricity consumption;
• a communication unit configured to connect the smart switch to a gateway of the smart home system in wired or wireless communication mode, and send the real-time electricity information and the total electricity consumption to the gateway a storage unit configured to store a formula and an electrovalence, wherein the calculating module further calculates energy charge of the electronic device according to the formula stored in the first storage, and the control module controls the screen to display the energy charge;
• and
• a button connected to the processor unit, configured to send a first signal to the processor unit in response to a first pressing gesture;
• wherein the control module resets the total electricity consumption and the energy charge of the electronic device displayed on the screen and the calculating module calculates the total electricity consumption and the energy charge of the electronic device in response to the first signal.
