Oops, that's not quite right. I just clicked on the motion sensor in the app and it showed me that you also need a control hub for the motion sensor (which I don't have myself). I can't find the product on Galaxus, but there is a set at: https://mi-store.ch/produkt... and the motion sensor would be included.

Should work, yes (but I don't have a motion sensor yet - hence "should").

You need:
- a Xiaomi motion sensor, e.g. Xiaomi Motion Sensor
- WLAN range where you want to install the devices
- A smartphone with Xiaomi Home A
