Fragrancing and/or deodorizing a cleaning appliance

A method carried out by one or more devices, comprising:

• capturing first information or obtaining captured first information indicative of an odor load in the interior of a cleaning appliance, wherein the first information is captured from at least one odor sensor;
• producing fragrancing and/or deodorizing information based at least in part on the captured or obtained first information or outputting the captured first information in order to produce the fragrancing and/or deodorizing information, wherein the production of the fragrancing and/or deodorizing information comprises a comparison between the captured or obtained first information and a predefined threshold;
• initiating fragrancing and/or deodorization by at least one actuator for releasing a fragrancing and/or deodorizing agent based on the fragrancing and/or deodorizing information produced;
• capturing second information or obtaining captured second information indicative of an ingress of light and/or a temperature in the interior of the cleaning appliance, wherein the second information is captured by at least one light sensor and/or at least one temperature sensor;
• and
• adapting the predefined threshold by a zero point calibration when the temperature has dropped below a predefined temperature threshold and the ingress of light has signaled emptying of the cleaning appliance.
