How can I get a response from my device via the Mozart API?
Use curl along these lines:
curl --request GET \
--url http://192.168.*.*:80/api/v1/setup/remotes \
--header 'Accept: application/json'
You could also try the BeoNetRemote platform, that works with devices such as "Contour" and "Beosound 2": https://documenter.getpostman.com/view/1053298/T1LTe4Lt#0ea7e41f-9b15-4be7-8560-5fdae05754ee
