Examples relate to an edge controller apparatus, to an edge controller method, to an edge controller computer program, and to systems comprising an edge controller apparatus. The edge controller apparatus comprises at least one interface for obtaining status data of a plurality of sensors or actuators and for communicating with a remote server. The edge controller apparatus comprises processing circuitry configured to obtain a plurality of units of status data of the plurality of sensors or actuators, the plurality of sensors or actuators being part of machinery or being arranged in an environment of the machinery. The processing circuitry is configured to update at least one model representing the status of the sensors or actuators based on the plurality of units of status data. The processing circuitry is configured to provide the updated at least one model representing the status of the sensors or actuators to the remote server.
