A method for controlling, by an electronic device, at least another device in a wireless communication system, wherein the at least another device is placed in a real world environment, the method comprising: obtaining, by the electronic device, a digital representation of the real world environment; identifying, by the electronic device, at least one device from the digital representation; obtaining, by the electronic device, status information for the at least one identified device; rendering, by the electronic device, the digital representation of the real world environment on a display, wherein the digital representation includes a graphical representation of the at least one identified device based on the status information for the at least one identified device; receiving, by the electronic device, a user-input indicative of control information for executing one or more operations of the at least one identified device; and transmitting, by the electronic device, the control information for executing the one or more operations to the at least one identified device, wherein the method is characterised by: identifying, by the electronic device, whether a variation of the status information of the at least one identified device exceeds a predetermined threshold; wherein the status information is a parameter value of the identified device; and representing, by the electronic device, an audio indicator corresponding to the variation in response to the amount of the variation of the status information exceeding the predetermined threshold, wherein representing the audio indicator comprises: obtaining, by the electronic device, the audio indicator from a database over a network; obtaining, by the electronic device, location information of the at least one identified device; detecting, by the electronic device, an audio output device located in proximity to the identified device of which the amount of the variation exceeds the predetermined threshold, based on the location information of the at least one identified device; and controlling, by the electronic device, the detected audio output device to play the audio indicator. obtaining, by the electronic device, a digital representation of the real world environment; identifying, by the electronic device, at least one device from the digital representation;
