Hello,
Can anyone suggest if there is such a relay that would work as in the attached clumsy drawing.
.
In a nutshell, the idea is to switch on the lighting, in this case two LED strips using a light switch.
The first strip would be connected to the existing lighting installation + 12V transformer, in front of which a relay would be connected, which would switch on the LEDs and give a radio signal to the second relay (radio?) connected at the 230V line socket de facto switching on and off the current in the socket (transformer and second LED strip connected to the socket). With the light switch we switch both strips on and off at the same time.
