Hi! Hm… Looks like the SiriusMX information is not coming out in JSON format correctly from the SonosAPI.
I think you may have to contact Jimmi about this. Open an issue here: https://github.com/jishi/node-sonos-http-api/issues and describe your problem. As soon as the “output” is in correct JSON format, it should be working. Usually hes quick in fixing things. :)
