Hi @Automated_House, Sorry I dont understand your question, do you want to use the fire tv like ST speaker? the answer : maybe is possible, Fire TV have the DLNA app, but I dont known if is compatible , the software mediarenderer change the id each time is turned on, or maybe do not send all information, if the app have all DLNA settings it must work, but no one has confirmed it works
sorry if I misunderstand your question
