WiFi switch surface mounting

Hi all,

i am new in this forum. I am trying to setup my smart/automation system but i need some suggestion to find some device.

What i am looking for is a smart wifi switch, the switch should be surface monted (i need to add a new switch without breaking the wall) and i can put the receiver to turn on the ceiling lamp directly in the lamp ( where i already have power).

Can you suggest something?

Thanks a lot
Regards
Giovanni
