The world we live in would be unimaginable without technology. Technology makes everyday life easier for people. What we will discuss in this paper is technology that helps us manage energy in a world of renewable energy sources, in a world of electric cars, etc. In this paper, we will demonstrate the capabilities of the Smart1 controller and how it influences the operation of other systems so that the user can extract the maximum potential from their facility. This final paper discusses how the Smart1 controller works and what it consists of, and we will also present an example of a facility where the Smart1 controller is installed. In the first part of this paper, we will present the components of the Smart1 controller itself and its options within the Smart1 software, and in the second part, we will show an example of a facility managed by the Smart1 controller. For the purposes of this paper, I used the Smart1 Config Software.
