Play my music from deezer on musiccast

I have a family account 

Hi ​@Raviv To connect Deezer to Yamaha MusicCast, open the MusicCast Controller app, select your device, choose "Deezer" from the service list, and log in with your credentials. Alternatively, connect your phone to the MusicCast device via Bluetooth or Airplay (iOS) to play audio. 
Thanks
