A method of calibrating a monitoring device (20) for monitoring movement of a movable component (2, 12, 19) of an elevator system (2) comprises detecting (120) a travel time (t.sub.k) between a starting time (t.sub.k) and a stopping time (t.sub.k) as well as acceleration (a(t)) of at least one movement of the movable component (2, 12, 19); determining (130, 140) a travel distance of the movable component (2, 12, 19) by integrating the detected acceleration (a(t)) twice with respect to the detected travel time (t.sub.k); correlating (150) the determined travel distance (s.sub.k) with the detected travel time (t.sub.k) to form a pair of travel time and travel distance; and storing (160) the pair of travel time and travel distance (t.sub.k,s.sub.k) as part of a travel profile (34).

An elevator system is described. The system includes a landing door having a landing door lintel, a landing door sill, and a landing door column, a landing door lock located in one of the landing door lintel and the landing door column, and a column-integrated step integrated into the landing door column, wherein the column-integrated step is deployable from a stowed state to a deployed state, wherein when in the deployed state, the column-integrated step provides a step for access to the landing door lock.

An elevator door control system comprises a door sensor, a door motor control unit, a transmission unit being wired by a cable as part of or all of a transmission path between the door sensor and the door motor control unit, a storage unit to store a change in a binary signal indicating detection of an obstacle in association with a door position at a time of the change in the binary signal. A partially broken state of the cable is determined by evaluating reproducibility of the door position at the time of the change in the binary signal on the basis of the timing of the change in the binary signal and a door position at the time of the change in the binary signal. The partially broken state of the cable caused by repeated bending deformation of the cable can be determined.

According to an aspect, there are provided methods and apparatuses for configuring wireless devices in an elevator system. According to an aspect, an elevator car is caused to perform a travel in an elevator shaft. Wireless signal strength values and a device identifier associated with each detected wireless device are recorded based on wireless signals from the wireless devices at landing floors with an elevator car mounted wireless device during the travel. Data is received from the elevator car mounted wireless device, the data comprising for each detected wireless device the device identifier of the detected wireless device and data associated with the wireless signal strength values of the detected wireless device. Each detected wireless device at the landing floors is associated with a specific landing floor based on the data received from the elevator car mounted wireless device.
