1. A method for detecting, the method comprising:
receiving a plurality of current sensor measurements at a server system, the plurality of current sensor measurements received from a lighting control system communicably coupled to the server system and remote from the lighting control system, the plurality of current sensor measurements including at least two shot sample measurements and at least two steady state sample measurements obtained from a luminaire electrically connected to the lighting control system and a light bulb electrically connected to the luminaire, the at least two steady state sample measurements respectively including a first measurement of a current profile over a period of at least 2 seconds with the luminaire and the light bulb connected to the luminaire powered at full power, the at least two shot sample measurements respectively including a second measurement of the current profile when the luminaire is switched on and switched back off via the lighting control system;
measuring how close each of the respective current sensor measurements is to one of a plurality of model current curves via dynamic time warping; and
determining at least one of a luminaire type and a light bulb type of the luminaire and the light bulb connected to the lighting control system based on the measurements.
