    Abstract: According to an aspect, a method includes monitoring a plurality of vibration data by a vibration monitoring beacon and determining that the vibration monitoring beacon has been installed at a service location based on detecting an installation characteristic signature in the vibration data. The vibration monitoring beacon can transition into a learning mode based on determining that the vibration monitoring beacon has been installed at the service location. The method can also include monitoring for a learning mode termination event and transitioning the vibration monitoring beacon from the learning mode to a normal operation mode based on detecting the learning mode termination event.

    Abstract: A method for monitoring thresholds for performance attributes in an elevator system is provided. Aspects includes collecting, by a sensor affixed to an elevator car, sensor data associated with the elevator system wherein the sensor data comprises one or more performance attribute values for a set of performance attributes of the elevator system. Obtaining a threshold profile associated with the elevator system, wherein the threshold profile comprises thresholds for each performance attribute in the set of performance attributes of the elevator system. Comparing the one or more performance attribute values to corresponding thresholds for the set of performance attributes and transmitting an alert for any of the one or more performance attribute values exceeding the corresponding thresholds for the set of performance attributes.

    Abstract: A method of monitoring motion of a conveyance apparatus within a conveyance system is provided. The method including: detecting a first atmospheric air pressure proximate the conveyance apparatus at a first time and a second atmospheric air pressure proximate the conveyance apparatus at a second time using the pressure sensor located on the conveyance apparatus; determining a change in atmospheric air pressure proximate the conveyance apparatus in response to the first and second atmospheric air pressure; detecting a height change of a conveyance apparatus in response to at least the change in atmospheric air pressure; and confirming or disconfirming the height change using at least one of a rate of change in atmospheric air pressure prior to the first time, an acceleration of the conveyance apparatus, a rate of change in static atmospheric air pressure, a rate of change in temperature, and a rate of change in relative humidity detection.
