New to RFLink - want to connect Smartwares SH5-RPS-36A

[HGFBoris]

Hello!
I attached a Arduino Mega and RFLink Board (from Nodo Shop) to my Raspi and Domoticz yesterday. I Already added successfully a PIR - running well. Today I bought a Smartwares SH5-RPS-36A Plug - but what now? How can I connect this to Domoticz?

I have read a lot of stuff... but doesn't have any better clue...

Could somebody please help!

Thanks

Boris
