Method for controlling elevator system by using computer-controlled mobile system

The invention relates to a method (400) for controlling an elevator system (100) by using a computer-controlled mobile device (102). In this case, the elevator installation (100) comprises an elevator shaft (106), which has a plurality of shaft sleepers (112) associated with each floor, an elevator car (104), which has car sleepers (110), which can be moved along the elevator shaft (106), and a control unit (120) for the method (400) of the elevator car (104). The mobile device (102) has an evaluation unit (300) which is designed to communicate with the control unit (120). In the method (400), first of all, in an evaluation unit (300), an evaluation unit (300) receives at least one component (122, 124, 125, 124) using the at least one component (122, 124, 125) of the mobile device (102); information (306, 308, 312) is generated on the basis of a height deviation (114) between the car sleeper (110) and a current shaft sleeper (112) located opposite the car sleeper (110) in the case of the car sleeper (110, 302
