5. The apparatus (1) according to claim 4, characterized in that the projection (124) is arranged to come into direct contact with the coffee beans received in the chamber (10).

6. The apparatus (1) according to any one of claims 3 to 5, characterized in that the cavity (123) is formed by an engraving on the side wall (12).

7. The apparatus (1) according to any one of the preceding claims, characterized in that the temperature sensor (90) is arranged to transmit a first signal related to the detected temperature to display the detected temperature, such as to display the detected temperature on a user interface (31) or display unit and / or to display the detected temperature on the user device, which is wirelessly connected to the apparatus (1) or temperature sensor (90), and / or wherein the temperature sensor (90) is arranged to transmit a first signal related to the detected temperature to determine the presence of the camera (10) based on the detected temperature and / or the detected electrical resistance.

8. The apparatus (1) according to any one of the preceding claims, further comprising a control unit configured to control the device (80) for roasting coffee beans, preferably based on the first transmitted signal from the temperature sensor (90) and / or based on a second signal related to a roasting temperature detected by an additional temperature sensor of the apparatus (1), characterized in that the control unit is preferably configured to determine the presence of the chamber (10) based on the first received signal and to prevent the roasting of the coffee beans by the device (80) after not receiving a first signal or the first signal exceeding or falling below a defined threshold value or range.

9. The apparatus (1) according to any one of the preceding claims, characterized in that the apparatus (1), preferably the control unit, is configured to apply a correction factor to the temperature detected by the temperature sensor (90), wherein the correction factor preferably depends on the geometry and / or characteristics of the side wall material (12).

10. The apparatus (1) according to any one of the preceding claims, characterized in that the apparatus (1) further comprises a user interface (31) or a display unit preferably configured to display the detected temperature based on the first and / or second transmitted or received signal, and / or wherein the apparatus (1) further comprises a communication interface for wireless communication with a user device such as a smartphone.

11. The apparatus (1) according to any one of the preceding claims, further comprising a receptacle (14), characterized in that the receptacle (14) comprises the chamber (10), wherein the receptacle (14) is preferably detachably attached to the apparatus (1).

12. The apparatus (1) according to claim 11, characterized in that the receptacle (14) comprises a handle (16), wherein the handle (16) is arranged in such a way that at least in a plan view of the receptacle (14) the handle (16) covers the temperature sensor (90).

13. The apparatus (1) according to any one of the preceding claims, characterized in that the temperature sensor (90) is fixedly arranged with respect to the chamber (10) such that the temperature sensor (90) moves together with the chamber (10) when the chamber (10) moves, such as when the receptacle (14) is separated, or wherein the temperature sensor (90) is arranged to remain fixed when the chamber (10) moves, such as when the receptacle (14) is separated.

14. The apparatus (1) according to any one of the preceding claims, characterized in that the device (80) is arranged to generate an air current to agitate the coffee beans received in the chamber (10), and / or wherein the device (80) is arranged to generate a heated air current to roast the coffee beans received in the chamber (10), wherein the device (80) preferably comprises a heating unit for heating the air current.

15. The apparatus (1) according to any one of the preceding claims, characterized in that the apparatus is a household appliance.
