The present invention relates to a dosing device with a dosing chamber in which a displacement element is movably arranged in such a way that it is movable to and fro between two positions, wherein the volume of the dosing chamber in one position is greater than in the other position. The dosing device moreover has an actuator for driving the displacement element, which actuator has an actuator input for an electrical control signal and is constructed in such a way that an electrical control signal present at the actuator input is converted into a mechanical movement. Moreover, the dosing device has a sensor for detecting a physical or chemical parameter, which sensor has a sensor output for an electrical measurement signal and is configured in such a way that it detects the physical or chemical parameter, converts it into an electrical measurement signal and makes the latter available at the sensor output. Finally, the dosing device has a communications interface via which the dosingdevice can communicate with a remote server.
