Light switch france

I have a house with already light switches, I was wondering what are you guys using in France as a zigbee or zwave switch (or any other).
I don’t think I have a lot of space inside the socket to fit a sonoff mini (plus I need to fit 2 sonoff mini inside on a double switch).
I need either a smaller than sonoff mini, or a switch that already has zigbee.
It seems that it’s something hard to find.
Thank you.
