Domoticz

I have recently bought 3 switches from Conrad.

I am trying to add them to my Domoticz system but nothing i try works.
I don't have a working Remote so that's no help.

I there anybody how knows how to connect to these switches?

First question, what are you using, RFLink or RFXcom transceiver?
Second question, are they on the supported device list of your transceiver?

I am using a RFXcom, and as far as the compatibility , in the user manual i states is i use the ext2 firmware it supports Conrad-RSL.
