Abstract: Methods and systems for making elevator service requests, the methods including receiving, by a computing device comprising a processor, building information, populating a first scrollable wheel and a second scrollable wheel with floor information contained within the building information, displaying a user interface, including the first scrollable wheel and the second scrollable wheel, on a display of the computing device, receiving a first user input at the first scrollable wheel including a first list element located within a first selection box, receiving a second user input at the second scrollable wheel including a second list element located within a second selection box, receiving a user input request to make an elevator service request, generating an elevator service request packet based on the first user input and the second user input, and transmitting the elevator service request packet to an elevator controller to make an elevator service request.

Abstract: A method for connecting a mobile device to an elevator system, the mobile device executing a mobile application for issuing elevator calls to the elevator system, includes: determining a geographical location of the mobile device; obtaining a list of buildings within a geographical range of the geographical location of the mobile device; determining if a registered building is in the list of buildings, the registered building being a building at which a user has registered with the elevator system; and automatically establishing a connection between the mobile device and the elevator system at the registered building.

Abstract: A method includes receiving, from a portable recording device, multiple recordings of sounds made by an elevator during operation of the elevator, the multiple recordings generated at different times. The method includes analyzing, by a sound analysis circuit, the multiple recordings generated at the different times to detect changes in an elevator characteristic over time and generating, based on detecting the changes in the elevator characteristic over time, a notification to perform an action on the elevator.
