Primjećuje li štedan gost nešto od struje na predplatu?

A thrifty guest first and foremost notices that their credit barely decreases: the display records their consumption, but does not judge. Without this module, they have no insight into what their thrifty behavior brings them. With a reasonable price per kWh, there is often credit left at the end of their stay, which they can leave standing or get paid back. They don't receive unpleasant surprises or subsequent questions about high consumption; this only affects the guest who truly uses a lot of electricity.
