just take a break and leave my desk to go out for a walk.
While i was walking in just notice that the solution is very simple i think.
There's a joint box in my wall where all the live line's come together.
I can go from there to my L in of my sonoff. is this correct thinking?

Isn't the Shelly not a solution for you?

You know, the scheme is really great! But are you sure that it will suit you? Or someone else? The most important element of the system is the driver, which is located in the base of the device. It is a combination of transformer, capacitors and microchips. The cost of LED lighting sources depends on the quality of this part. The driver is used to convert AC to DC and stabilize the incoming voltage. Another function is the power supply of LEDs. Based on this, we can conclude that this is very individual. Each LED lamp is different in many ways.
