OK, your best bet is probably going to be to get an in wall micro and then you can use it with any dumb switch that you want. 
Because you need to 220 V, though, The US Z wave frequency options are very limited, and they aren’t going to be inexpensive.
So if I were in your situation I would look at a Sonoff Wi-Fi micro. Most of their models can handle 220 V, but verify that.
Talk to the people in the following thread, and they should be able to help you figure out a configuration.
