A dosing system (1, 2) for positioning in the interior of an automatic dishwasher, comprising • at least one cartridge for flowable washing or cleaning agents, having a plurality of chambers (3a, 3b, 3c) for spatially separated reception of preparations, each different from one another, of a washing or cleaning agent, and • a dosing device couplable to the cartridge, comprising • at least one energy source, • a control unit, • a sensor unit, • at least one actuator that is connected to the energy source and to the control unit in such a way that a control signal of the control unit produces a movement of the actuator, • a closure element that is coupled to the actuator in such a way that a movement of the actuator shifts the closure element into a closed position or a delivery position, • at least one dosing chamber that, with the cartridge and dosing device in the assembled state, is communicatingly connected to at least one of the cartridge chambers (3a, 3b, 3c), • wherein the dosing chamber comprises an inlet for the inflow of washing or cleaning agent from a cartridge chamber (3a, 3b, 3c) and an outlet for the outflow of washing or cleaning agent from the dosing chamber into the environment, • wherein at least the outlet of the dosing chamber is closable or uncoverable by the closure element, wherein the dosing device comprises at least one first interface that interacts with a corresponding interface, embodied in or on an automatic dishwasher, in such a way that a wireless transfer of signals, which represent in particular operating-state, measurement, and/or control information items of the dosing device and/or of the automatic dishwasher, from the automatic dishwasher to the dosing device and from the dosing device to the automatic dishwasher is brought about, wherein the interfaces are configured for the emission and/or reception of optical signals, and at least one interface is embodied as an optical transmitting unit having a light-emitting means, in particular an LED, that preferably radiates light in the IR region; and at least one interface is embodied as an optical receiving unit, in particular selected from the group of photocells, photomultipliers, semiconductor detectors, photodiodes, photoresistors, solar cells, phototransistors, CCD and/or CMOS image sensors, which preferably receive light in the IR region, wherein the optical signal is embodied as a sequence of signal pulses having a pulse duration of between 1 ms and 10 seconds, preferably between 5 ms and 100 ms. • at least one cartridge for flowable washing or cleaning agents, having a plurality of chambers (3a, 3b, 3c) for spatially separated reception of preparations, each different from one another, of a washing or cleaning agent, and • a dosing device couplable to the cartridge, comprising • at least one energy source, • a control unit, • a sensor unit, • at least one actuator that is connected to the energy source and to the control unit in such a way that a control signal of the control unit produces a movement of the actuator, • a closure element that is coupled to the actuator in such a way that a movement of the actuator shifts the closure element into a closed position or a delivery position, • at least one dosing chamber that, with the cartridge and dosing device in the assembled state, is communicatingly connected to at least one of the cartridge chambers (3a, 3b, 3c), • wherein the dosing chamber comprises an inlet for the inflow of washing or cleaning agent from a cartridge chamber (3a, 3b, 3c) and an outlet for the outflow of washing or cleaning agent from the dosing chamber into the environment, • wherein at least the outlet of the dosing chamber is closable or uncoverable by the closure element, • at least one energy source, • a control unit, • a sensor unit, • at least one actuator that is connected to the energy source and to the control unit in such a way that a control signal of the control unit produces a movement of the actuator, • a closure element that is coupled to the actuator in such a way that a movement of the actuator shifts the closure element into a closed position or a delivery position, • at least one dosing chamber that, with the cartridge and dosing device in the assembled state, is communicatingly connected to at least one of the cartridge chambers (3a, 3b, 3c), • wherein the dosing chamber comprises an inlet for the inflow of washing or cleaning agent from a cartridge chamber (3a, 3b, 3c) and an outlet for the outflow of washing or cleaning agent from the dosing chamber into the environment, • wherein at least the outlet of the dosing chamber is closable or uncoverable by the closure element, • wherein the dosing chamber comprises an inlet for the inflow of washing or cleaning agent from a cartridge chamber (3a, 3b, 3c) and an outlet for the outflow of washing or cleaning agent from the dosing chamber into the environment, • wherein at least the outlet of the dosing chamber is closable or uncoverable by the closure element,
