Hello (sorry for my english , i'm French)
I want to share with you some small finds.
a touch-sensitive 3-button wall button that can send 7 different actions.
in more simple:
button 1 = 1 code
button 2 = another code
button 3 = another code
"But it's not over !!!"
button 1 and 2 at the same time = still another code sent (different from the button code 1 and different from the code button 2)
same principle for button 1 and 3, or button 2 and 3 or button 1 and 2 and 3.

for info
after many purchase, testing (and even disassembly) wall button battery in 433,92Mhz.
It can be seen that most works with an ev1517 chip (which with 4 input can generate 15 different code).

and that many are identical seen from outside
But unfortunately most do not fully utilize the potential of the ev1517 chip and therefore can not detect when multiple keys are pressed

model managing the "multitouch":

and an example of another which seems identical that I bought but which unfortunately does not manage the "multitouche":

following the comments, if you wish I will send you the pictures of the interior to be able to make the difference visible on the electronic level

Good night
