I want to switch 230 Volt. However, I do not want to touch anything but low voltage devices.
This is for safety reasons and because the insurance won’t pay me nothing if I fiddle with my 230V installation.
What I want to do is the following:
RPI (5V) or mysensors switch (5V) -> 5V or 12V relais ->230V relais (which need 12V or 24V)
I want to us a switching power supply 230V to 12V supply and a 12V to 5V supply to provide the voltages.
I am now wondering, what would be the best solution, using standard 5V relais or SSRs.
I found these on ebay:

For switching the 230V I would use something like this:
As I said, I don’t want to touch any of the 230V (even if I have experience with it). A professional would install the 230V side and I could then play with the low voltage side.
What do you think about this setup?
