Hello
When I plug my Shelly Dimmer into my electrical system according to the instructions, it blows up the system.
Initially, I had a simple connection (a simple plug and a lamp) represented by diagram 1
I inserted the Shelly between the socket and the lamp but it does not work. This is a dimmable LED system (see diagram 2)
Do you know why ?
Hi and welcome to the forum. 
Two dimmer don't work together, sorry.
I don't understand your feedback. There is only one dimmer in my case ... What would you say ?
The LED is not dimmable itself but it's compatible.
If I understand your pictures correctly, you have installed a dimmer (the rotary switch) and a Shelly dimmer.
And that's exactly what doesn't work.
