Abstract
A method for identifying sensor units (3) at fault in a lighting system (1) performed using three or more sensor units (3), each respective one of the sensor units (3) comprising a respective sensor (116) configured to generate sensor data, the method comprising at an external processing apparatus (20) external to the sensor units (3): receiving from each of the sensor units (3) the sensor data; generating correlation parameters from the sensor data for selected pairs of neighbouring sensor units (3); and monitoring the correlation parameters to determine a sensor unit (3) at fault.
