Xiaomi Aqara Wall Switch universal wall socket (single)

hello all , i made this universal wall socket box for the Xiaomi Aqara Wall Switch.

i bought the xiaomi smart switch and i found out that they use square junktion boxes in china and i live in europe and we have small round junktion boxes , i didnt want to cut out the wall so i maked this design!

So if you dont want to cut out your wall use this box! you only need to drill 2 holes and the existing junkion boxes keeps existing!
