Help with wiring the smart curtain controller

Hi all,

I need your help to correctly install a smart curtain controller to my traditional wall switch.

smart curtain controller

Long short story: I've bought two from aliexpress and one blew it up when I connected it to my wall switch. The wall switch It's powered (as you can see in the images).

The other one worked but without the wall switch.

Two gang Wall switch (M stands for motor) for electric roller shutter

I don't understand how I can use the wall switch buttons with these devices.

Thanks in advance.

Great day for all of you.

PS: With Shelly 2.5 I didn't get this problem, which makes me doubt this kind of device.
