Question about Marmitek Invisible Control 6 Xtra

I have unfortunately had the same experience with the Marmitek Invisible Control 6 XTRA in connection with my Dreambox. It simply does not work. I have therefore (of necessity) invested again and decided on the Marmitek Invisible Control 6 (https://www.digitec.ch/de/s1/product/marmitek-invisible-control-6-fernbedienungserweiterung-437850). The "small" difference is not only the missing "XTRA", but also the fact that on the device without "XTRA" the IR forwarding lines are glued directly to the IR receiver on the device. This definitely works better with my units than the "XTRA" system. Here, the IR forwarding must be placed somewhere in the reception range of the units.
