                                                            1. Maintenance prediction

                                                            Any anomaly in the elevator's I/O pin or register value is reported as a fault. The ML model uses the GPIO pin and generated fault to predict the level of maintenance required. Elevator status changes can be traced through GPIO pin changes.

                                                            2. Live elevator monitoring

                                                            A smart elevator shares dynamic information like the current position, direction, state, and door status of an elevator. The information is sent to the IoT central hub, and a live update is shared on the user interface. This feature allows remote monitoring of the elevator, location, status, and the fault.

                                                            3. Remote controlling

                                                            The IoT central system eliminates the need for physical human intervention. Smart elevators use voice commands and can be controlled remotely through mobile apps for functions such as start-stop or switch on/off actions. The technology reduces the need for physical switches and unnecessary human resources for maintenance.

                                                            4. Remote testing

                                                            Faults in smart elevators will be identified using the GPIO pin, and technicians can look at the GPIO value to debug the elevator issues remotely. The elevator's active high value and GPIO pin testing value allows the technician to remotely identify the causes of elevator failure.

                                                            5. Cost-effectiveness

                                                            The cost of hiring an elevator technician is very high. IoT allows central control of an elevator. It can be remotely operated and tested, reducing the technician cost. Power consumption can also be reduced by setting the rules for usage and time threshold.

                                                            6. Zero downtime

                                                            Elevator downtime can be reduced by utilizing IoT. You can track power failures and specify rules for when an elevator should be started on backup. Track further timeout of the backup power, and elevator downtime can be reduced by setting up rules for usage during a power cut.

                                                            The future of the IoT elevators market

                                                            The IoT elevator market has the potential to grow manifold in the coming years owing to the rising demand for smart equipment in construction. The recent advancements in IoT and AI technologies are making elevators smarter, leaving room for greater automation.

                                                            The time and cost of maintenance and repair also reduce with the decrease in human intervention. In addition to remote monitoring and controlling by the 2030s, the elevators are predicted to have 'minds of their own.'

                                                            In a new smart building ecosystem, elevators can communicate with servers to deliver a better user experience - with minimum hassle and no downtime.

                                                            You can also expect the next generation of IoT elevators to include machines that can hold doors longer for elderly passengers, offer a tailored journey based on facial recognition, and help determine the optimal time to leave and return home.

                                                            If you are keen to undertake an IoT application development project  that can offer similar benefits to your end customers, you have come to the right place.
