Hello and thank you very much for the help! :) I have now done the following: My Macro Group now only contains one page. From this page I can then jump to a "Macro" with one Button. However, this macro is not a macro, but a normal device. Thats how it works! Thanks again :) I bought the Pronto RU940 (TSU-2000) back in 2001. In the meantime, I use one in the bedroom and one in the living room. I also bought 4 or 5 pieces as a reserve;) cheaply used.
Together with the "Light Manager Air" the possibilities are practically unlimited.[Link: jbmedia.eu]
The Light Manager Air can send and receive commands via LAN, WIFI, TCP, radio, infrared, Alexa etc. etc. There is practically nothing that does not work with the Pronto, because it can also generate a suitable Pronto command for each command, which it then understands again later.
I don't even know the Marantz parts. I thought the functionality would be the same as with Philips? Best regards Surfy
