Thought you were Greek like me all this time (or a Greek living at Czech republic maybe?)
For our subject, a wifi (and IFTTT enabled) switch would be great (as long as a bridge is no needed).
Even if Xiaomi switch worked in Singapore server, we are talking about a very simple switch without many functions. The wall switch has 2 buttons that you can assign a single click and a double click function to each one and the small round remote switch has only one button that you can assign single/double/long press. Not bad but not ideal for a smart light. I would like something with dedicated buttons for dimming, temp etc.
Anyway probably there are agreements between Xiaomi and Yeelight for this so i dont think it can be done.
What we are all have been waiting for and yeelight must press Xiaomi on this, is for Xiaomi to have its products (Gateway, sensors etc) in Singapore server.
