Find the deviceid of a KlikAanKlikUit device

I’m using HA for a while now. One thing I failed to figure out is finding the complete deviceid. The only way is connecting the RFXCOM to my laptop. Is there an other way I don’t know?

Set the parameter to add new devices received temporarily ON.
Enable the AC protocol in the RFXtrx.
Switch the KAKU devices with the KAKU remote.
Disable the parameter to add new devices received.

Sorry, but this is no news to me. After added the device I want the full ID. Something like this: 0B11000F022EFF9601040F70.
