It is not possible to reduce the size of your bills by replacing the meter alone. This way of saving money works only in conjunction with constant monitoring of consumption figures and certain steps to reduce electricity consumption. The meter is designed to make it easier to analyse the energy efficiency of the house. On the basis of the information obtained, it is possible to draw graphs when the most energy is consumed, which appliances have higher energy consumption, and then it is necessary to consider options for a more rational approach to the work of appliances. Heat savings in the flat are also important, as heating appliances tend to be the most energy consuming.
