Typically a technician is physically present to investigate a malfunction of an elevator system. Devices, systems and methods are provided for actively monitoring one or more lift devices, such as elevators and escalators. A computing system for electrically controlling an elevator controller, includes: a field board electrically connected to an elevator controller, and the field board communicates with a computing platform device, which in turn is connected to a server over the Internet. The field board includes relay switches that are electrically connected to the elevator controller. The server sends poking commands that triggers a relay switch to open or close, which causes the elevator controller to generate a call signal to move the elevator to an upper or a lower floor. If the elevator does not move according to a poking command, then a malfunction is reported.
