Method for monitoring the operating status of an energy delivery network, in which method - sensors (12a-c), which are provided at measurement locations assigned to primary components of the energy delivery network, acquire measured values indicating an operating status of the energy delivery network; and - on the basis of the measured values or values derived therefrom, a monitoring device of the operator of the energy delivery network generates a visualization that indicates the operating status of the energy delivery network at the measurement location of the particular sensor (12a-c), wherein - the measured values or values derived therefrom are transmitted from the sensors (12a-c) first to an application server, the operator of which is different from influence of the operator of the energy delivery network; - the application server analyses and/or processes the measured values or the values derived therefrom, thereby forming system status values which indicate the operating status of the energy delivery network at the measurement location of the particular sensor (12a-c); - the system status values are transmitted from the application server to the monitoring device of the operator of the energy delivery network; and - the monitoring device uses the system status values received from the application server to generate and display the visualization indicating the operating status of the energy delivery network at the measurement location of the particular sensor (12a-c); characterized in that - the application server interacts with a configuration device, which, when the operator of the energy delivery network procures a new sensor (12a-c), transmits to the application server a unique sensor identifier together with an operator identifier specifying the operator of the energy delivery network; and - on being put into operation, the sensor (12a-c) uses its unique sensor identifier to register with the application server. - sensors (12a-c), which are provided at measurement locations assigned to primary components of the energy delivery network, acquire measured values indicating an operating status of the energy delivery network; and - on the basis of the measured values or values derived therefrom, a monitoring device of the operator of the energy delivery network generates a visualization that indicates the operating status of the energy delivery network at the measurement location of the particular sensor (12a-c), - the measured values or values derived therefrom are transmitted from the sensors (12a-c) first to an application server, the operator of which is different from influence of the operator of the energy delivery network; - the application server analyses and/or processes the measured values or the values derived therefrom, thereby forming system status values which indicate the operating status of the energy delivery network at the measurement location of the particular sensor (12a-c); - the system status values are transmitted from the application server to the monitoring device of the operator of the energy delivery network; and - the monitoring device uses the system status values received from the application server to generate and display the visualization indicating the operating status of the energy delivery network at the measurement location of the particular sensor (12a-c); - the application server interacts with a configuration device, which, when the operator of the energy delivery network procures a new sensor (12a-c), transmits to the application server a unique sensor identifier together with an operator identifier specifying the operator of the energy delivery network; and - on being put into operation, the sensor (12a-c) uses its unique sensor identifier to register with the application server.
