I just found this diagram on the web, have to check it but a first look looks prommising.

@Tigroenot this is a picture of the EU dubble switch version.

But what I am looking for is how to connect the arduino to this PCB
The picture of DJONvI is a good start, but I want to know if the SMD components which where added are resistors or a before I blow up the PCB

Well, somehow I got over it

Here is a working sketch for livolo two button switch:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

I am also playing around with the livolo dubble switch, but I am still figuring out how to control the switch via the header on the Switch board (thus without the base unit).
Can you share also your hardware setup, this will be very helpfull for me.
Thanks in advance.
