Abstract: The present invention relates to a method, a system and a computer program product for detecting and/or predicting need for elevator maintenance. A first digital twin of the elevator is generated using data collected by one or more sensors of an unmanned aerial vehicle (UAV) operating within the elevator shaft. One or more threshold values are defined for parameters associated with one or more components of the elevator appearing in the first digital twin. At least one second digital twin of the elevator is generated using data collected by one of more sensors of an unmanned aerial vehicle (UAV) within the elevator shaft. Each parameter of the elevator in the at least one second digital twin is compared to the respective one or more first threshold values. A request for maintenance of the one or more components of the elevator is automatically triggered if any one of the compared parameters meets or goes beyond the respective first threshold value.
