Please help with klik aan klik uit devices and RFXCOM - can't get my lights switched on

I switched from Domoticz to HA. My Raspberry Pi3 has a RFXCOM devices connected and it works fine. It automatically detects new devices and adds them to my devices and entities.

But, the biggest problem are my current dimmer lights. I don’t know how to get them added and working. I already viewed a lot of Youtube videos and read a lot of posts but a little help to get these lights working should be very appreciated.
