USmart is a powerful comprehensive energy management app, which integrates functions such as plant and station management, data report, electricity analysis, plant and station report, and operation and maintenance management. It is convenient for customers to view and manage their energy-consuming equipment. [Warm Tips] When the app first uses the positioning function, it will ask you if you have the original positioning function enabled. After you agree to always turn on the App location function, even if the App is switched to the background, the location refresh function is also working, which will reduce the battery life of your phone, please know.
