First you have to pair the devices with the CCU2.
Then you have to config the connection between the CCU2 and Homey in the Homey Homematic App. After a successful connection process you can add the Homematic devices with Homey, if they are supported by the app.
Actually I‘m not at home, so I can’t have a look into the settings of the CCU, so it could be that there have to make some settings to. Tomorrow I will habe a look into and let you know.
BTW, there is no need to do some settings in the CCU-Jack interface.
