摘要： The invention relates to a system (400) comprising a data processing unit (402) and/or a central database (403), and a grid (100) of a plurality of building technology sensor modules (101a-d). Each of the sensor modules (101a-d) comprises light sensor (103), preferably a daylight sensor, an acoustic sensor (105), a motion sensor (107), a controller (109) which is configured to receive output signals from said sensors (103, 105, 107), and an interface, preferably a wireless interface (111), for a communication between the controller (109) and a gateway (401) for forwarding sensor information signals (130) to the data processing unit (402) and/or the central database (403), wherein said sensor information signals (130) comprise a timestamp, an identifier of a sensor module (101a-d) and a sensor value. The data processing unit (402) and/or the central database (403) carry out a first data analysis of the forwarded sensor information signals (130), preferably by machine learning, for evaluating correlations between sensor information signals (130) of sensors (103, 105, 107) of different categories and/or of different sensor modules (101a-d), wherein the system (400) is designed to detect incorrect data provided by one or more sensors (103, 105, 107) based on the first data analysis, and to ignore, replace or correct such incorrect data.
