Abstract

The present invention relates to a method, a system and a device for detecting a change of state of a household appliance, such as a refrigerator or a freezer, comprising a temperature-controlled space. For the space, a first parameter is detected which is representative of a change of pressure in said space, and a second parameter, a message being given if a parameter value deviates by a predetermined size from an initial value, and determining that detection of a change of state has occurred.
