All solved now. Thank you so much for your feedback!
My first end second try was only one way (all ML > BLC > NL) or the other way (only BS9000 ML > BLC > NL). This step is the both ways and that did the trick.
Now all works as I like it to be and as it should be for regular users like my family members. I could even source the BS9000 Radio source to N.RADIO (just for fun).
I was aware of the N.RADIO/N.MUSIC sw problem. But if the BS9000 is out of the ML chaink as Audiomaster, like it is now, all BV’s are new enough to work around that. Also the chips with later sw is only for sale for the BS9000 MKIII as far as I am aware of.
Also interesting to know, the IR mapping of each BLC is only for the BLC itself. As I am not using the IR eye, those settings are obsolute untill you attach an IR eye.
Those BLC’s are pretty nice devices once you get them to know. Will try find some extra ones. Especially for linking a future BLI to the BLGW, but maybe also to make all current sources visible as networklink sources in the ML devices in the BeoLiving app.
Thank you again.
Kind regards, Peter
