Question about Xiaomi Smartmi Fan Heater

Cable firmly connected to the device, no adapter included. Why are crappy foreign devices actually sold here and not even an adapter supplied with them? I pay Swiss prices here at a Swiss shop and get real ones for abroad. Insolence!!!! I'll complain about it tomorrow.

Not at all. You need a plug-on adapter for the Schuko, the cable supplied by Galaxis is useless here. On the device side, the cable is a fixed connection; in addition to the four visible screws, there are two more under the warranty seal.

Unplug it and then plug in the new one...

Unplug and plug in something else.
