Abstract: A domestic appliance, which may be a cooling device, such as a refrigerator, includes: a treatment chamber that can be closed by a pivotable door; at least one camera arranged in the door for recording images from the treatment chamber when the door is open; and a door movement sensor for detecting values of at least one parameter of a door movement. The door movement sensor has at least one inertial sensor. At least one camera and the at least one inertial sensor are integrated in a camera/sensor module which is arranged in the door. The camera/sensor module has a communication device, at least for outputting image data from the camera of the camera/sensor module. The domestic appliance is configured to trigger at least one device function upon the detection of at least one trigger value.
