Split sound

[maverik80]

hi guys, i'm creating an automation for a web radio that splits the sound from one Echo to another. in the following automation the sound starts on one or the other but then I would like to have it excluded and play respectively on the other but this does not happen, it starts playing my Echo show and then splits it on the other Echo dot but instead they start playing together ... thanks to those who help me
