The invention concerns a method for detecting anomalous events in a driver device of a building infrastructure system, a corresponding driver device, e.g. a light driver device, and a building infrastructure system. The method comprises, in a usage profile generating phase, obtaining parameter data for at least one physical parameter of the driver device during operation of the driver device in the building infrastructure system during a predefined time period; and generating a usage profile for the driver device based on the obtained parameter data. The generated usage profile includes characteristic parameter ranges for the at least one physical parameter determined based on the obtained parameter data. In a subsequent monitoring phase, the method obtains current parameter data for the at least one physical parameter of the driver device, then determines whether an anomalous event in the driver device has occurred by comparing the obtained current parameter data with the usage profile of the driver device. The method generates and outputs a signal generated based on the determined anomalous event.
